>>> some_string = '[PERSON] Len Strousand'
>>> some_string.removeprefix('PERSON') # Strict substring matching
'[PERSON] Len Strousand'
>>> some_string.removeprefix('[PERSON] ') # Note the whitspace
'Len Strousand'
>>> some_string.removeprefix('[PERSON]').split() # Chaining
['Len', 'Strousand']

Python Tip: PEP 616

lstrip() versus removeprefix()

>>> 'Arthur: three!'.lstrip('Arthur: ') # Character set recursively applied
'ee!'
>>> 'Arthur: three!'.removeprefix('Arthur: ') # Substring applied once
'three!'

str.removeprefix() and str.removesuffix()

are standard starting in Python 3.9!
