I'm just starting out with python. I'm trying to find the index of char present more than once
This is the sample string
08:28:57,990 DEBUG [http-0.0.0.0-18080-33] [tester] [1522412937602-580613] [TestManager] ABCD: loaded 35 test accounts
How should get the index of '[' and ']' present around 'TestManager' .
