Updated series documentation to close #35406

[TAJD]

• [x ] closes BUG: Creating a Series from a Series results in all NaN values #35406
• [x ] tests added / passed
• [ x] passes black pandas
• [ x] passes git diff upstream/master -u -- "*.py" | flake8 --diff
• whatsnew entry

Not sure how to do whatsnew entry for this - first contribution! Do let me know how to improve.

Output of scripts/validate_docstring.py:

################################################################################ ########################## Docstring (pandas.Series) ########################## ################################################################################ One-dimensional ndarray with axis labels (including time series). Labels need not be unique but must be a hashable type. The object supports both integer- and label-based indexing and provides a host of methods for performing operations involving the index. Statistical methods from ndarray have been overridden to automatically exclude missing data (currently represented as NaN). Operations between Series (+, -, /, *, **) align values based on their associated index values-- they need not be the same length. The result index will be the sorted union of the two indexes. Parameters ---------- data : array-like, Iterable, dict, or scalar value Contains data stored in Series. .. versionchanged:: 0.23.0 If data is a dict, argument order is maintained for Python 3.6 and later. index : array-like or Index (1d) Values must be hashable and have the same length as `data`. Non-unique index values are allowed. Will default to RangeIndex (0, 1, 2, ..., n) if not provided. If data is dict-like and index is None, then the values in the index are used to reindex the Series after it is created using the keys in the data. dtype : str, numpy.dtype, or ExtensionDtype, optional Data type for the output Series. If not specified, this will be inferred from `data`. See the :ref:`user guide <basics.dtypes>` for more usages. name : str, optional The name to give to the Series. copy : bool, default False Copy input data. ################################################################################ ################################## Validation ################################## ################################################################################ 3 Errors found: Parameters {'fastpath'} not documented See Also section not found No examples section found
