PEP 616 – String methods to remove prefixes and suffixes | peps.python.org
March 19, 2020 - Within the tuple, only the first matching affix would be removed. This was rejected on the following grounds: This behavior can be surprising or visually confusing, especially when one prefix is empty or is a substring of another prefix, as in 'FooBar'.removeprefix(('', 'Foo')) == 'FooBar' or 'FooBar text'.removeprefix(('Foo', 'FooBar ')) == 'Bar text'.

Finally a remove prefix, sufix string method in Python 3.9
This strikes me as bloat since replace() and rfind() can be used already. related to user confusion about the existing str.lstrip and str.rstrip methods This is a user issue, not a language issue. It is stated quite clearly in documentation what those functions do. Why add in a crutch because people can't read? https://docs.python.org/3/library/stdtypes.html#str.lstrip LITERALLY STATES: "The chars argument is not a prefix; rather, all combinations of its values are stripped" https://docs.python.org/3/library/stdtypes.html#str.rstrip Again, LITERALLY STATES: "The chars argument is not a suffix; rather, all combinations of its values are stripped" several users on Python-Ideas [2] reported frequently including similar functions in their code for productivity. The implementation often contained subtle mistakes regarding the handling of the empty string, so a well-tested built-in method would be useful. Again, that's a user issue and not a language issue in my opinion. or to use regular expressions as in the expression re.sub('' + re.escape(prefix), '', s) Really ?! More on reddit.com

how to remove part of a file name recursively in python?
What you want to do is remove the prefix. Your prefix is 31 chars >>> len("The.Simpsons.The.Simpsons.clear") 31 >>> t="The.Simpsons.The.Simpsons.clearThe.SimpsonsSeason 1 EP7 The Call of the Simpsons.mkv" >>> t[31:] 'The.SimpsonsSeason 1 EP7 The Call of the Simpsons.mkv' A bit of advice: before you do something permanent like renaming files, print out new names just to make sure they look ok.

Here's one approach using re.sub:
import re
l = ['[ 1.1 ] 1. a electronic bill presentment system.','[ 1.2 ] a network.']
[re.sub(r'\[\s*\d+\.*\d*\s*\]\s+(?:\d+\.\s*)?', '', s) for s in l]
# ['a electronic bill presentment system.', 'a network.']
See demo
Testing with a larger list of strings:
l = ['[ 1.1 ] 1. a electronic bill presentment system.',\
'[ 1.2 ] a network.',\
'[ 1.3 ] a plurality of first stations, each associated with a respective one of a plurality of users and operable to transmit first requests for bills of its associated user via the network.',\
'[ 1.5 ] a plurality of second network stations, each associated with a respective one of a plurality of billers, configured to receive the transmitted second requests for bills and to transmit, responsive thereto, the requested bills of the associated user via the network.',\
'[ 1.6 ] wherein the bill availability information for the associated user identifies those of the plurality of billers having a bill available for that user without identifying an amount of the bill of each of the identified billers for the associated user.',\
'[ 2.1 ] 2. a method for presenting electronic bills.']
[re.sub(r'\[\s*\d+\.*\d*\s*\]\s+(?:\d+\.\s*)?', '', s) for s in l]
['a electronic bill presentment system.',
'a network.',
'a plurality of first stations, each associated with a respective one of a plurality of users and operable to transmit first requests for bills of its associated user via the network.',
'a plurality of second network stations, each associated with a respective one of a plurality of billers, configured to receive the transmitted second requests for bills and to transmit, responsive thereto, the requested bills of the associated user via the network.',
'wherein the bill availability information for the associated user identifies those of the plurality of billers having a bill available for that user without identifying an amount of the bill of each of the identified billers for the associated user.',

You should regular expression to substitute the pattern with an empty string
>>> re.sub(r'\[\s?\d\.\d\s?]\s?(\d(\.\s)?)?', '', '[ 1.1 ] 1. a electronic bill presentment system.')
'a electronic bill presentment system.'

'ING. AGR. ROBERTO DANIEL RODRÍGUEZ',
'C.P.N. JULIO DOMINGO BURAK',
'INGENIERO HIDRÁULICO VÍCTOR AGUSTÍN PORRINO'
]
new_names = [re.sub("^\s+", "", i.split(".")[-1]) for i in names]
print new_names # [SEBASTIÁN LASTIRI', ROBERTO DANIEL RODRÍGUEZ', JULIO DOMINGO BURAK', 'INGENIERO HIDRÁULICO VÍCTOR AGUSTÍN PORRINO']

'LIC. SEBASTIAN LASTIRI',
'ING. AGR. ROBERTO DANIEL RODRIGUEZ',
'C.P.N. JULIO DOMINGO BURAK',
'INGENIERO HIDRAULICO VICTOR AGUSTIN PORRINO'
]
for i in names:
res = re.split(r'\.\s*(?=[^.]+$)', i)
if len(res) > 1:
print res[1]
else:
print res[0]
Output:
