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

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
