Remove spaces from user input string in Python

Question

how can I remove whitespaces from within a user input string? Can't I use .replace(" ","") ? it didn't work for me.
My code:

>>>p=raw_input ("Enter phrase:\n")    
>>>p.replace(" "."")

It still outputs user input phrase WITH spaces..what am I doing wrong?Please help.

Answer 1

由于字符串在 python 中是不可变的，因此str.replace返回一个新字符串，它不会修改现有字符串

p = p.replace(" ","")

Answer 2

You can use replace, but you have to assign its return to the variable

>>>p=raw_input ("Enter phrase:\n")

>>>p=p.replace(" ","")
