Column contains column 3

Question

I have a dataframe. I would like to test whether, (C), on each row, the number in column (B) is in the string, column (A).

df = pd.DataFrame({\'A\': [\"me 12         


        

Answer 1

Values NaNs are floats, so you can convert output to floats:

df['C'] = df.A.str.extract('(\d+)', expand=False).astype(float).eq(df.B,0).astype(int)
