Find String Pattern Match In Pandas Dataframe And Return Matched Strin

I have a dataframe column with variable comma separated text and just trying to extract the values that are found based on another list. So my dataframe looks like this: col1 | col

Solution 1:

You might like to use extract, or one of the other vectorised string methods:

In [11]: s = pd.Series(['a', 'a,b'])

In [12]: s.str.extract('([cdfb])')
Out[12]:
0    NaN
1      b
dtype: object
