Replace a string located between

Question

Here is my problem: in a variable that is text and contains commas, I try to delete only the commas located between two strings (in fact [ and ]).

Answer 1

Here is a non-regex method. You can replace your [] delimiters with say [/ and /], and then split on the / delimiter. Then every odd string in the split list needs to be processed for comma removal, which can be done while rebuilding the string in a list comprehension:

>>> Variable = "The sun shines, that's fine [not, for, everyone] and if it rains,
                it Will Be better."
>>> chunks = Variable.replace('[','[/').replace(']','/]').split('/')
>>> ''.join(sen.replace(',','') if i%2 else sen for i, sen in enumerate(chunks))
"The sun shines, that's fine [not for everyone] and if it rains, it Will Be 
 better."
