Python remove all apostrophes from a string

Question

I wanted to remove all occurrences of single and double apostrophes in lots of strings.

I tried this-

mystring = "this string shouldn't have any apostrophe - \' or \" at all"
print(mystring)
mystring.replace("'","")
mystring.replace("\"","")
print(mystring)

It doesn't work though! Am I missing something?

`mystring.replace("'", "")` will print the edited string. – Ben Morris Mar 12 '15 at 14:51 — Ben Morris, Mar 12 '15 at 14:51

Replace is not an in-place method, meaning it returns a value that you must reassign.

mystring = mystring.replace("'", "")
mystring = mystring.replace('"', "")

In addition, you can avoid escape sequences by using single and double quotes like so.

worth mentioning why replace is not in-place - Python strings are immutable. – user3012759 Mar 12 '15 at 15:33

Strings are immutable in python. So can't do an in-place replace.

f = mystring.replace("'","").replace('"', '')
print(f)

This is what finally worked for my situation.

#Python 2.7
import string

companyName = string.replace(companyName, "'", "")

Using regular expression is the best solution

import re
REPLACE_APS = re.compile(r"[\']")

text = " 'm going"
text = REPLACE_APS .sub("", text)

input = " 'm going" output = " m going"
