Trailing whitespace is any spaces or tabs after the last non-whitespace character on the line until the newline   In your posted question  there is one extra space after try   and there are 12 extra spaces after pass    gt  gt  gt  post text                        if self tagname and self tagname2 in list1                      try                           question   soup find  div    post-text                           title   soup find  a    question-hyperlink                           self list2 append str title  str question  url                          current    1                     except AttributeError                          pass                             logging info   s questions passed   s questions                       collected     count  current                   count    1             return self list2          gt  gt  gt  for line in post text splitlines            if line rstrip      line              print repr line                         try                         pass                See where the strings end  There are spaces before the lines  indentation   but also spaces after   Use your editor to find the end of the line and backspace  Many modern text editors can also automatically remove trailing whitespace from the end of the line  for example every time you save a file

This is just a warning and it doesn t make problem for your project to run  you can just ignore it and continue coding  But if you re obsessed about clean coding  same as me  you have two options    Hover the mouse on warning in VS Code or any IDE and use quick fix to remove white spaces  Press f1 then type trim trailing whitespace
