Check if a value exists in pandas dataframe index

Question

I am sure there is an obvious way to do this but cant think of anything slick right now.

Basically instead of raising exception I would like to get True

Answer 1

with DataFrame: df_data

>>> df_data
  id   name  value
0  a  ampha      1
1  b   beta      2
2  c     ce      3

I tried:

>>> getattr(df_data, 'value').isin([1]).any()
True
>>> getattr(df_data, 'value').isin(['1']).any()
True

but:

>>> 1 in getattr(df_data, 'value')
True
>>> '1' in getattr(df_data, 'value')
False

So fun :D
