Answer 1

您可能需要阅读“使用Python Pandas和XlsxWriter”文档和Pandas Cookbook IO（Excel） 。

另一个有用的选择是使用像ipython或Jupyter Notebook这样的交互式Python shell - 只需键入function / method / constructor name，然后输入? （问号）然后按Enter - 它会显示一个docstring 。

ipython演示：

In [84]: pd.ExcelWriter?
Init signature: pd.ExcelWriter(path, engine=None, **kwargs)
Docstring:
Class for writing DataFrame objects into excel sheets, default is to use
xlwt for xls, openpyxl for xlsx.  See DataFrame.to_excel for typical usage.

Parameters
----------
path : string
    Path to xls or xlsx file.
engine : string (optional)
    Engine to use for writing. If None, defaults to
    ``io.excel.<extension>.writer``.  NOTE: can only be passed as a keyword
    argument.
date_format : string, default None
    Format string for dates written into Excel files (e.g. 'YYYY-MM-DD')
datetime_format : string, default None
    Format string for datetime objects written into Excel files
    (e.g. 'YYYY-MM-DD HH:MM:SS')

Notes
-----
For compatibility with CSV writers, ExcelWriter serializes lists
and dicts to strings before writing.
