Please somebody tell me why the code is not working?

I was solving the 'The spy life' problem in the community section.Here's the code; def message(spy): char="@#

amp;&/?!*;:-+£¢€¥√1235467890|π÷׶∆©®%✓\~" for i in char: if i in msg: new=msg.replace(i,"") new2=new[::-1] return new2 msg=input() print(message(msg))

In if : new=msg.replace(i,"") # making new string in new new2=new[::-1] #reversing return new2 #returning so only first match is replaced , reversed, exit loop.. It will not continue.. instead complete loop by changing **original string.. **After loop, outside if, and loop => reverse it and return.

Snehil Pandey Pls don't give finished code as answer, because it makes the OP skip the most important part of learning process. Pls remember this is a learning app. Instead, prefer giving hints for the OP to find the solution.

import re text = str(input()) result = re.sub(r"[^\w\s]", "", text) res = re.sub(r"\d", "", result) def reverse(res): res = res[::-1] return res print (reverse(res)) #I've used regular expression

Jayakrishna🇮🇳 Thanks for the suggestion but how can I remove the unwanted letters without looping it.

Vaibhav Pandey If you don't want to use loop then try regex way as in @Snehil Panday code. re.sub(r"[^\w\s]", "", text) will return all replaced by empty "" char, except a word and space in text string.. re.sub(r"\d", "", text) will return all replaced by empty "" , except digits in the text string. Alternatively, re.findall(r"[a-zA-Z]", text ) will returns list of all characters from text string. Use join and reverse it just next.. one liner.
