Replace multiple characters in a string at once

Question

Please advise if the following code works. Mine seems not working at all

string = str(input('Enter something to change'))
replacing_words = 'aeiou'

for i in replacing_words:
    s = string.replace('replacing_words', ' ')

print(s)

My intension here is to replace all vowels in the string with a space. If this is a wrong code, could someone assist with right codes and explanation, why it didn't work?

Thank you

You could define a translation table. Here's a Python2 code:

>>> import string
>>> vowels = 'aeiou'
>>> remove_vowels = string.maketrans(vowels, ' ' * len(vowels))
>>> 'test translation'.translate(remove_vowels)
't st tr nsl t  n'

It's fast, concise and doesn't need any loop.

For Python3, you'd write:

'test translation'.translate({ord(ch):' ' for ch in 'aeiou'}) # Thanks @JonClements.
