Several functions using DataFrame.ix which has been removed from Pandas 1.0.0

See original GitHub issue

Pandas 1.0.0 has removed the DataFrame.ix indexer. This indexer was being used in several core functions including rebase() and calc_cagr(). In all, there are 11 instances of this indexer being used in the core module. Pandas also seems to have become aggressive in their policy of requiring users to update. It would be good to update the indexer to the suggested .iloc or .loc, as appropriate.

Hey folks,

❯ python
Python 3.8.2 (default, Mar 11 2020, 00:29:50)
[Clang 11.0.0 (clang-1100.0.33.17)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import ffn
>>> ffn.__version__
(0, 3, 4)

But if I look in my python3.8/site-packages/ffn/core.py

      def display_monthly_returns(self):
          """
          Display a table containing monthly returns and ytd returns
          for every year in range.
          """
          data = [['Year', 'Jan', 'Feb', 'Mar', 'Apr', 'May',
                   'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec', 'YTD']]
          for k in self.return_table.index:
              r = self.return_table.ix[k].values.             <<<<<<< uses "ix"
              data.append([k] + [fmtpn(x) for x in r])
          print(tabulate(data, headers='firstrow'))

But in master

I see

    def display_monthly_returns(self):
        """
        Display a table containing monthly returns and ytd returns
        for every year in range.
        """
        data = [['Year', 'Jan', 'Feb', 'Mar', 'Apr', 'May',
                 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec', 'YTD']]
        for k in self.return_table.index:
            r = self.return_table.loc[k].values             <<< uses loc: OK
            data.append([k] + [fmtpn(x) for x in r])
        print(tabulate(data, headers='firstrow'))

This code changed happened in August 4 2018 with this commit

But the Pypi package never got updated: https://pypi.org/project/ffn/#history

@JordanPlatts or @pmorissette or any maintainer, can you guys please bump up the version and upload latest ffn to Pypi?

Thanks a lot!

I am busy with work and can’t spend time of bt or ffn. Feel free to fix the issues and I can merge them.
