Python re.sub use non-greedy mode (.*?) with end of string ($) it comes greedy!

Question

Code:

str = \'

A
B\'
print(re.sub(r\'\\w$\', \'\', str))

It is expected to return


Answer 1

The non-greediness won't start later on like that. It matches the first and will non-greedily match the rest, which actually need to go to the end of the string because you specify the $.

To make it work the way you wanted, use

/\w$/

but usually, it is not recommended to use regex to parse HTML, as some attribute's value can have < or > in it.
