反馈Bug和增加新功能

Bug reports are an important part of making pandas more stable. Having a complete bug report will allow others to reproduce the bug and provide insight into fixing. See this stackoverflow article and this blogpost for tips on writing a good bug report.

Trying the bug-producing code out on the master branch is often a worthwhile exercise to confirm the bug still exists. It is also worth searching existing bug reports and pull requests to see if the issue has already been reported and/or fixed.

Bug reports must:

  1. Include a short, self-contained Python snippet reproducing the problem. You can format the code nicely by using GitHub Flavored Markdown:

    1. >>> from pandas import DataFrame
    2. >>> df = DataFrame(...)
    3. ...

  2. Include the full version string of pandas and its dependencies. You can use the built in function:

    1. >>> import pandas as pd
    2. >>> pd.show_versions()

  3. Explain why the current behavior is wrong/not desired and what you expect instead.

The issue will then show up to the pandas community and be open to comments/ideas from others.
