We can often find the modulere in the standard library modules but it can be replaced (if it is possible). I don't suggest removing it everywhere, there are places where its use is appropriate, but there are also places where it is an unnecessary solution and leads to unpleasant consequences (they can be found below)

Cons of regular expressions and reasons to replace regular expressions with functions and methods:

1. We spend time to compile re pattern (one time, but anyway we spend it)
2. In most cases simple string methods are faster (according to my benchmarks about 2x)
3. We can removeimport re which will affect import time
4. Additionally: I think for those who don't know regular expressions, the code is more difficult to read and therefore difficult to maintain.
