Exact match of string in pandas python

  A
0 Good to 1. Good communication EI : tathagata.kar@ae.com
1 SAP ECC Project System  EI: ram.vaddadi@ae.com
2          


        

Answer 1

Thanks for the help. But seems like I found a solution that is working as of now.

Must use str.contains(r'(?:\s|^|Ei:|EI:|EI-)'+ls[i]) This seems to solve the problem.

Although thanks to @IsaacDj for his help.
