Code Coach Python Symbols

Is there a simpler way of removing all symbols from a string with regular expressions? import re input = input() output = "" pattern = re.compile(r"\w|\s") for i in input: if pattern.findall(i): output += i print(output)

yes, it can be done in one line if you dont count the import line. check out my code buts in my profile. import re #one liner is shorter print("".join(re.findall(r"[A-Za-z\d\s]+", input())))

Thanks! I didn’t quite get it working that way but it led me to this: import re input = input() output = re.sub(r"[^\w\s]", "", input) print(output)

Here without regex print(''.join(e for e in input() if e.isalnum() or e==' '))

Here's how I did mine. import re print(''.join(re.findall(r'\w|\s', input())))

def clean_string(string): new_string = "" for i in string: if i.isalpha() or i.isspace() or i.isdigit() == True: new_string += i return new_string string = input() print(clean_string(string))

My solution: y = "qwertzuiopasdfghjklyxcvbnm QWERTZUIOPASDFGHJKLYXCVBNM1234567890" x = input() output = "" for i in x: if i in y: output += i else: continue print(output)

Yes. You can change it to: pattern = re.compile(r"\W|\S") #anything that isn't a letter, underscore, or space Then, you should use re.sub: output = re.sub("", pattern) #removes anything that is a symbol

import string symbols = string.punctuation scrambled = input() table = str.maketrans("", "", symbols) stripped = scrambled.translate(table) print(stripped)

My solution with python mess = input() message ="" alphabet=" 1234567890abcdefghijklmnopqrstuvwxyz" for i in mess : for j in alphabet : if i == j or i == j.upper (): message += i print(message)
