[GitHub] [beam] damccorm opened a new issue, #20573: Series.str.repeat zipping operation produces incorrect proxy

[GitBox <gi...@apache.org>]

damccorm opened a new issue, #20573:
URL: https://github.com/apache/beam/issues/20573

   https://github.com/apache/beam/pull/13139#discussion_r513684704
   
   This proxy is incorrectly inferred as bool.
   
   ```
   
   In [10]: proxy.dtypes
   Out[10]: 
   str        object
   repeats     int64
   dtype: object
   
   In [11]: proxy.str.str.repeat(proxy.repeats)
   Out[11]:
   Series([], Name: str, dtype: bool)
   
   ```
   
   
   The actual operation does produce object though:
   
   ```
   
   In [13]: df.str.str.repeat(df.repeats)
   Out[13]: 
   0      AAA
   1        B
   2     CCCC
   3    DDDDD
   4
         EE
   Name: str, dtype: object
   
   ```
   
   
   Currently we work around this by specifying the proxy manually, maybe it can be fixed upstream?
