python regular expression regex

Question

I want to remove all the vowels from the string. but the following code doesn't work. Instead I need to put escape character before ^
i.e obj=re.compile(r'[\^aeiouAEIOU]')

import re

def disemvowel(string):
    obj=re.compile(r'[^aeiouAEIOU]')   
    k=obj.sub('',string)
    return k

s='This website is for losers LOL!'  
print( disemvowel(s) )

You actually want to remove vowels, so obj=re.compile(r'[aeiou]', re.I) — Nick

Actually your current character class [^aeiouAEIOU] will match everything except for vowels. Try this version:

s = "This website is for losers LOL!"
out = re.sub(r'[aeiou]', '', s, flags=re.IGNORECASE)
print(s + "\n" + out)

This prints:

This website is for losers LOL!
Ths wbst s fr lsrs LL!

An easy way to do this is :

import re

string = "This website is for losers LOL!"
print(re.sub("[aeiouAEIOU]","",string))

To remove vowels, you match all the vowels from your string and replace it by '', so, there is no need to add ^ inside []:

import re

def disemvowel(string):
    obj=re.compile(r'[aeiou]', re.I)   
    k=obj.sub('',string)
    return k

s='This website is for losers LOL!'  
print(disemvowel(s))
# Ths wbst s fr lsrs LL!

Try this :

def rem_vowel(string):
    vowels = ('a', 'e', 'i', 'o', 'u')
    for x in string.lower():
        if x in vowels:
            string = string.replace(x, "")

    print(string)

string = "This website is for losers LOL!"
rem_vowel(string)
