How to check whether the special characters are present in a string?

Question

I have to check the given special characters (#,@,$,*,%,!,&) in a string. String also includes letters and digits.

Answer 1

I personally like Oma Falk's code. It is very pythonic, very clear and straight forward, and it has a good readability.

I have made some extra additions for:
- using pre-defined string for special characters
- giving a list with all special characters found (with duplicates)
- giving a list with all special characters found (without duplicates)
- giving the total count of special characters found

Answer 11

I don't know why people think regex is hard, but I think it becomes ridiculously simple once you get the concept.

By the way, here's the code:

import re

string = "jhgr#66£"

ptrn = re.compile(r"[@#$!%&*]")

print(bool(ptrn.search(string)))
