How to print list items which contain new line?

Question

Answer 1

A first attempt:

l = ["1\n2"]
print(repr(l).replace('\\n', '\n'))

The solution above doesn't work in tricky cases, for example if the string is "1\\n2" it replaces, but it shouldn't. Here is how to fix it:

import re
l = ["1\n2"]
print(re.sub(r'\\n|(\\.)', lambda match: match.group(1) or '\n', repr(l)))
