The above solutions suggesting the use of regex aren't ideal because this is such a small task and regex requires more resource overhead than the simplicity of the task justifies.

Here's what I do:

myString = myString.replace(' ', '').replace('\t', '').replace('\n', '')

or if you had a bunch of things to remove such that a single line solution would be gratuitously long:

removal_list = [' ', '\t', '\n']
for s in removal_list:
  myString = myString.replace(s, '')

If you want to remove multiple whitespace items and replace them with single spaces  the easiest way is with a regexp like this    gt  gt  gt  import re  gt  gt  gt  myString  I want to Remove all white  t spaces  new lines  n and tabs  t   gt  gt  gt  re sub   s       myString   I want to Remove all white spaces  new lines and tabs     You can then remove the trailing space with  strip   if you want to

Use str split  sep   maxsplit    with no sep or sep None   From docs      If sep is not specified or is None  a different splitting algorithm is   applied  runs of consecutive whitespace are regarded as a single   separator  and the result will contain no empty strings at the start   or end if the string has leading or trailing whitespace    Demo    gt  gt  gt  myString split     I    want    to    Remove    all    white    spaces     new    lines    and    tabs     Use str join on the returned list to get this output    gt  gt  gt      join myString split     I want to Remove all white spaces  new lines and tabs
