[issue45334] String Strip not working

[Vigneshwar Elangovan]

New submission from Vigneshwar Elangovan <vigneshwar.e14 at gmail.com>:

string = "monitorScript_cpu.py"
a = string.strip("monitorScript_")
print(a)
  ----> getting output => u.py
Should stip only "monitorScript_" but stripping additional 2 charaters "monitorScript_cp" 

Below code working fine:
string = "monitorScript_send_user.py"
a = string.strip("monitorScript_")
print(a)
