Defaults to True for array input and False for Index/Series. Even when False for Index/Series, a shallow copy of the data is made. Set to False to avoid copying array input at your own risk (if you know the input data won't be modified elsewhere). Set to True to force copying Series/Index input up front. See Also -------- DataFrame : Two-dimensional, size-mutable, potentially heterogeneous tabular data. Index : Immutable sequence used for indexing and alignment. Notes ----- Please reference the :ref:`User Guide ` for more information. Examples -------- Constructing Series from a dictionary with an Index specified >>> d = {"a": 1, "b": 2, "c": 3} >>> ser = pd.Series(data=d, index=["a", "b", "c"]) >>> ser a 1 b 2 c 3 dtype: int64 The keys of the dictionary match with the Index values, hence the Index values have no effect. >>> d = {"a": 1, "b": 2, "c": 3} >>> ser = pd.Series(data=d, index=["x", "y", "z"]) >>> ser x NaN y NaN z NaN dtype: float64 Note that the Index is first built with the keys from the dictionary. After this the Series is reindexed with the given Index values, hence we get all NaN as a result. Constructing Series from a list with `copy=False`. >>> r = [1, 2] >>> ser = pd.Series(r, copy=False) >>> ser.iloc[0] = 999 >>> r [1, 2] >>> ser 0 999 1 2 dtype: int64 Due to input data type the Series has a `copy` of the original data even though `copy=False`, so the data is unchanged. Constructing Series from a 1d ndarray with `copy=False`. >>> r = np.array([1, 2]) >>> ser = pd.Series(r, copy=False) >>> ser.iloc[0] = 999 >>> r array([999, 2]) >>> ser 0 999 1 2 dtype: int64 Due to input data type the Series has a `view` on the original data, so the data is changed as well. seriesr_namez list[str] _metadatarname>dtcatstrsparsei )r!r]_mgrNc Sn[U[5(aUcUcUSLdUczU(dG[R"S[ U5R S[ U5R S3[ SS9 URSS9n[R"X5 X@l g[U[[R45(a>USLa9Ub$[UR[!U55(aUR5nSnUcSn[U[5(afU(d_URSS9nU(dI[R"S[ U5R S[ U5R S3[ SS9 Sn["R$"XA[ U55nUb ['U5nUbUR)U5nUc9UbUO [+S 5n[-U5(dUb[/[!U5SS 9nO/n[U[05(a [3S 5eSn[U[45(a)UbUR7U5nU(d UR8nGO[U[R5(a'[-UR5(a [;S 5eGO[U[<5(aaUc'UR>nUR@RSS9nGOwURCU5nUR@nURES 5(aSnGO@[U[F5(aURIXU5upSnSnGO[U[5(aUc UR>nO2UR>RKU5(aU(a [MS 5eU(dI[R"S[ U5R S[ U5R S3[ SS9 SnOi[U[5(aOS[NRP"U5n[SU5(a-[-U5(dUc[R"[T5nUc([SU5(dU/n[+[-U55nO&[SU5(a[NRV"X5 [U[5(aOUb5[UR[!U55(dSnUR7US9nU(aURSS9nO![YXX55n[RZ"XUS9n[R"X5 X@l UR]S U5 g)NFz Passing a z to zK is deprecated and will raise in a future version.

This are the values as stored in the Block (ndarray or ExtensionArray depending on the Block class), with datetime64[ns] and timedelta64[ns] wrapped in ExtensionArrays to match Index._values behavior. Differs from the public ``.values`` for certain data types, because of historical backwards compatibility of the public attribute (e.g. period returns object ndarray and datetimetz a datetime64[ns] ndarray for ``.values`` while it returns an ExtensionArray for ``._values`` in those cases). Differs from ``.array`` in that this still returns the numpy array if the Block is backed by a numpy array (except for datetime64 and timedelta64 dtypes), while ``.array`` ensures to always return an ExtensionArray.

Find the indices into a sorted Series `self` such that, if the corresponding elements in `value` were inserted before the indices, the order of `self` would be preserved. .. note:: The Series *must* be monotonically sorted, otherwise wrong locations will likely be returned. Pandas does *not* check this for you. Parameters ---------- value : array-like or scalar Values to insert into `self`. side : {'left', 'right'}, optional If 'left', the index of the first suitable location found is given. If 'right', return the last such index. If there is no suitable index, return either 0 or N (where N is the length of `self`). sorter : 1-D array-like, optional Optional array of integer indices that sort `self` into ascending order. They are typically the result of ``np.argsort``. Returns ------- int or array of int A scalar or array of insertion points with the same shape as `value`. See Also -------- sort_values : Sort by the values along either axis. numpy.searchsorted : Similar method from NumPy. Notes ----- Binary search is used to find the required insertion points.

Otherwise, only the ones with different values are kept. keep_equal : bool, default False If true, the result keeps values that are equal. Otherwise, equal values are shown as NaNs. result_names : tuple, default ('self', 'other') Set the dataframes names in the comparison. Returns ------- Series or DataFrame If axis is 0 or 'index' the result will be a Series. The resulting index will be a MultiIndex with 'self' and 'other' stacked alternately at the inner level. If axis is 1 or 'columns' the result will be a DataFrame. It will have two columns namely 'self' and 'other'.

Only used for functions. If ``map`` is called with a mapping or ``Series``, an exception will be raised. If ``engine`` is not provided the function will be executed by the regular Python interpreter. Options include JIT compilers such as Numba, Bodo or Blosc2, which in some cases can speed up the execution. To use an executor you can provide the decorators ``numba.jit``, ``numba.njit``, ``bodo.jit`` or ``blosc2.jit``. You can also provide the decorator with parameters, like ``numba.jit(nogit=True)``. Not all functions can be executed with all execution engines. In general, JIT compilers will require type stability in the function (no variable should change data type during the execution). And not all pandas and NumPy APIs are supported. Check the engine documentation for limitations. .. versionadded:: 3.0.0 **kwargs Additional keyword arguments to pass as keywords arguments to `arg`. .. versionadded:: 3.0.0 Returns ------- Series Same index as caller. See Also -------- Series.apply : For applying more complex functions on a Series. Series.replace: Replace values given in `to_replace` with `value`. DataFrame.apply : Apply a function row-/column-wise. DataFrame.map : Apply a function elementwise on a whole DataFrame. Notes ----- When ``arg`` is a dictionary, values in Series that are not in the dictionary (as keys) are converted to ``NaN``. However, if the dictionary is a ``dict`` subclass that defines ``__missing__`` (i.e. provides a method for default values), then this default is used rather than ``NaN``. Examples -------- >>> s = pd.Series(["cat", "dog", np.nan, "rabbit"]) >>> s 0 cat 1 dog 2 NaN 3 rabbit dtype: str ``map`` accepts a ``dict`` or a ``Series``. Values that are not found in the ``dict`` are converted to ``NaN``, unless the dict has a default value (e.g. ``defaultdict``): >>> s.map({"cat": "kitten", "dog": "puppy"}) 0 kitten 1 puppy 2 NaN 3 NaN dtype: str It also accepts a function: >>> s.map("I am a {}".format) 0 I am a cat 1 I am a dog 2 I am a nan 3 I am a rabbit dtype: str To avoid applying the function to missing values (and keep them as ``NaN``) ``na_action='ignore'`` can be used: >>> s.map("I am a {}".format, na_action="ignore") 0 I am a cat 1 I am a dog 2 NaN 3 I am a rabbit dtype: str For categorical data, the function is only applied to the categories: >>> s = pd.Series(list("cabaa")) >>> s.map(print) c a b a a 0 None 1 None 2 None 3 None 4 None dtype: object >>> s_cat = s.astype("category") >>> s_cat.map(print) # function called once per unique category a b c 0 None 1 None 2 None 3 None 4 None dtype: object argzoThe parameter `arg` has been renamed to `func`, and it will stop being supported in a future version of pandas.rz The `func` parameter is requiredzAThe engine argument can only be specified when func is a function__pandas_udf__zNot a valid engine: rr)rrrr decoratorskip_nar6mapr) na_actionFrF)poprrrr#rrHrrrrrrrr) functoolspartial _map_valuesr)rrrenginerr>r[s rr Series.mapsXL <zz%( O"/1 !!CDD  D>> W6#344 #7z!BCC**.. !X- /Fff--jjtyyI&&tE&: : D>>$$T4V4D%%d%@   ::E JWW X  rcU$)z Sub-classes to define.

Parameters ---------- func : function, str, list or dict Function to use for aggregating the data. If a function, must either work when passed a Series or when passed to Series.apply. Accepted combinations are: - function - string function name - list of functions and/or function names, e.g. ``[np.sum, 'mean']`` - dict of axis labels -> functions, function names or list of such. axis : {0 or 'index'} Unused. Parameter needed for compatibility with DataFrame. *args Positional arguments to pass to `func`. **kwargs Keyword arguments to pass to `func`. Returns ------- scalar, Series or DataFrame The return can be: * scalar : when Series.agg is called with single function * Series : when DataFrame.agg is called with a single function * DataFrame : when DataFrame.agg is called with several functions See Also -------- Series.apply : Invoke function on a Series. Series.transform : Transform function producing a Series with like indexes. Notes ----- The aggregation operations are always performed over an axis, either the index (default) or the column axis. This behavior is different from `numpy` aggregation functions (`mean`, `median`, `prod`, `sum`, `std`, `var`), where the default is to compute the aggregation of the flattened array, e.g., ``numpy.mean(arr_2d)`` as opposed to ``numpy.mean(arr_2d, axis=0)``. `agg` is an alias for `aggregate`. Use the alias. Functions that mutate the passed object can produce unexpected behavior or errors and are not supported. See :ref:`gotchas.udf-mutation` for more details. A passed user-defined-function will be passed a Series for evaluation. If ``func`` defines an index relabeling, ``axis`` must be ``0`` or ``index``.

List-like includes list, tuple, array, Series, and must be the same size as the index and its dtype must exactly match the index's type. Returns ------- Series Series with changed index. See Also -------- DataFrame.set_index : Set row labels. DataFrame.reset_index : Remove row labels or move them to new columns. DataFrame.reindex_like : Change to same indices as other DataFrame. Examples -------- ``DataFrame.reindex`` supports two calling conventions * ``(index=index_labels, columns=column_labels, ...)`` * ``(labels, axis={{'index', 'columns'}}, ...)`` We *highly* recommend using keyword arguments to clarify your intent. Create a DataFrame with some fictional data. >>> index = ["Firefox", "Chrome", "Safari", "IE10", "Konqueror"] >>> columns = ["http_status", "response_time"] >>> df = pd.DataFrame( ... [[200, 0.04], [200, 0.02], [404, 0.07], [404, 0.08], [301, 1.0]], ... columns=columns, ... index=index, ... ) >>> df http_status response_time Firefox 200 0.04 Chrome 200 0.02 Safari 404 0.07 IE10 404 0.08 Konqueror 301 1.00 Create a new index and reindex the DataFrame. By default values in the new index that do not have corresponding records in the DataFrame are assigned ``NaN``. >>> new_index = ["Safari", "Iceweasel", "Comodo Dragon", "IE10", "Chrome"] >>> df.reindex(new_index) http_status response_time Safari 404.0 0.07 Iceweasel NaN NaN Comodo Dragon NaN NaN IE10 404.0 0.08 Chrome 200.0 0.02 We can fill in the missing values by passing a value to the keyword ``fill_value``. Because the index is not monotonically increasing or decreasing, we cannot use arguments to the keyword ``method`` to fill the ``NaN`` values. >>> df.reindex(new_index, fill_value=0) http_status response_time Safari 404 0.07 Iceweasel 0 0.00 Comodo Dragon 0 0.00 IE10 404 0.08 Chrome 200 0.02 >>> df.reindex(new_index, fill_value="missing") http_status response_time Safari 404 0.07 Iceweasel missing missing Comodo Dragon missing missing IE10 404 0.08 Chrome 200 0.02 We can also reindex the columns. >>> df.reindex(columns=["http_status", "user_agent"]) http_status user_agent Firefox 200 NaN Chrome 200 NaN Safari 404 NaN IE10 404 NaN Konqueror 301 NaN Or we can use "axis-style" keyword arguments >>> df.reindex(["http_status", "user_agent"], axis="columns") http_status user_agent Firefox 200 NaN Chrome 200 NaN Safari 404 NaN IE10 404 NaN Konqueror 301 NaN To further illustrate the filling functionality in ``reindex``, we will create a DataFrame with a monotonically increasing index (for example, a sequence of dates). >>> date_index = pd.date_range("1/1/2010", periods=6, freq="D") >>> df2 = pd.DataFrame( ... {"prices": [100, 101, np.nan, 100, 89, 88]}, index=date_index ... ) >>> df2 prices 2010-01-01 100.0 2010-01-02 101.0 2010-01-03 NaN 2010-01-04 100.0 2010-01-05 89.0 2010-01-06 88.0 Suppose we decide to expand the DataFrame to cover a wider date range. >>> date_index2 = pd.date_range("12/29/2009", periods=10, freq="D") >>> df2.reindex(date_index2) prices 2009-12-29 NaN 2009-12-30 NaN 2009-12-31 NaN 2010-01-01 100.0 2010-01-02 101.0 2010-01-03 NaN 2010-01-04 100.0 2010-01-05 89.0 2010-01-06 88.0 2010-01-07 NaN The index entries that did not have a value in the original data frame (for example, '2009-12-29') are by default filled with ``NaN``. If desired, we can fill in the missing values using one of several options. For example, to back-propagate the last valid value to fill the ``NaN`` values, pass ``bfill`` as an argument to the ``method`` keyword. >>> df2.reindex(date_index2, method="bfill") prices 2009-12-29 100.0 2009-12-30 100.0 2009-12-31 100.0 2010-01-01 100.0 2010-01-02 101.0 2010-01-03 NaN 2010-01-04 100.0 2010-01-05 89.0 2010-01-06 88.0 2010-01-07 NaN Please note that the ``NaN`` value present in the original DataFrame (at index value 2010-01-03) will not be filled by any of the value propagation schemes. This is because filling while reindexing does not look at DataFrame values, but only compares the original and desired indexes. If you do want to fill in the ``NaN`` values present in the original DataFrame, use the ``fillna()`` method.

This method prints information about a Series including the index dtype, non-NA values and memory usage. Parameters ---------- verbose : bool, optional Whether to print the full summary. By default, the setting in ``pandas.options.display.max_info_columns`` is followed. buf : writable buffer, defaults to sys.stdout Where to send the output. By default, the output is printed to sys.stdout. Pass a writable buffer if you need to further process the output. max_cols : int, optional Unused, exists only for compatibility with DataFrame.info. memory_usage : bool, str, optional Specifies whether total memory usage of the Series elements (including the index) should be displayed. By default, this follows the ``pandas.options.display.memory_usage`` setting. True always show memory usage. False never shows memory usage. A value of 'deep' is equivalent to "True with deep introspection". Memory usage is shown in human-readable units (base-2 representation). Without deep introspection a memory estimation is made based in column dtype and number of rows assuming values consume the same memory amount for corresponding dtypes. With deep memory introspection, a real memory usage calculation is performed at the cost of computational resources. See the :ref:`Frequently Asked Questions ` for more details. show_counts : bool, optional Whether to show the non-null counts. By default, this is shown only if the DataFrame is smaller than ``pandas.options.display.max_info_rows`` and ``pandas.options.display.max_info_columns``. A value of True always shows the counts, and False never shows the counts. Returns ------- None This method prints a summary of a Series and returns None.
