Hi All,

This is the case. To split "string2" from "string1_string2" I am using 
re.split('_', "string1_string2", 1)[1].

It is working fine for string "string1_string2" and output as "string2". But actually the problem is that if a sting is "__string1_string2" and the output is "_string1_string2". It is wrong.

How to fix this issue?
