我在哪里可以找到ExcelWriter文档

Question

I want to work with the ExcelWriter class. Though the ExcelWriter can be called with pd.ExcelWriter like in this post, I can't find any information about it in the Pandas API . So where can I find a documentation?

Answer 1

You may want to read "Working with Python Pandas and XlsxWriter" documentation and Pandas Cookbook IO (Excel) .

Another useful option is to use interactive Python shells like ipython or Jupyter Notebook - just type function/method/constructor name followed by ? (question mark) and press Enter - it'll show you a docstring .

Demo in ipython :

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.
