Check if string is in a pandas dataframe

Question

I would like to see if a particular string exists in a particular column within my dataframe.

I\'m getting the error

ValueError: The truth v

Answer 1

Pandas seem to be recommending df.to_numpy since the other methods still raise a FutureWarning: https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.to_numpy.html#pandas.DataFrame.to_numpy

So, an alternative that would work int this case is:

b=a['Names']
c = b.to_numpy().tolist()
if 'Mel' in c:
     print("Mel is in the dataframe column Names")
