You can try this:

for line in f:
    sub = re.sub('cell', 'module cell ', line)

re.sub takes three obligatory arguments:

re.sub(pattern, repl, string)

Where the pattern is what you're looking for, the replacement of the string, and string that remains when the found pattern is removed.

module cell abc
A1
A2
Z
module cell bpc
A1
A2
A3
Z
