Because [] defines a character class in a regex, if you want literal
[ and ] you need to escape them with backslash.
[prev 0 , now 1] -> match any single character from the set "prev0,now1 "
\[prev 0 , now 1\] -> match the actual text [prev 0 , now 1]
Try these:
re.search('[prev 0 , now 1]','p') # matches (p in "prev0,now1 ")
re.search('[prev 0 , now 1]','x') # doesn't match (x not in "prev0,now1 ")
re.search('\[prev 0 , now 1\]','p') # doesn't match
re.search('\[prev 0 , now 1\]','[prev 0 , now 1]') # matches
