In [12]: df.pat
Out[12]:
0 foo
1 bar
Name: pat, dtype: object
In [14]: 'bar' in df.pat
Out[14]: False
Why is the result False? How can I check that 'cronus' is in the column?

33 ways -- `'bar' in df.pat.values` or `df.pat.isin(['bar']).any()` or `(df.pat == 'bar').any()` – Zero Aug 06 '17 at 12:51
