[Python] eval 사용을 피하는 방법 1. getattr

https://stackoverflow.com/a/22156138

How can I replace `eval` in my function?

 

eval 기반 구현

from hashlib import * # added for clarification
def get_hash(self):
        if self.hash_type in ['md5', 'sha1', 'sha224', 'sha256', 'sha384', 'sha512']:
            data = eval(self.hash_type) # <--- how can I replace this?

 

getattr 기반 구현

import hashlib
if self.hash_type in ['md5', 'sha1', 'sha224', 'sha256', 'sha384', 'sha512']:
     func = getattr(hashlib, self.hash_type)
