Run your program with  python -t script py   This will warn you if you have mixed tabs and spaces   On  nix systems  you can see where the tabs are by running  cat -A script py   and you can automatically convert tabs to 4 spaces with the command  expand -t 4 script py  gt  fixed script py   PS  Be sure to use a programming editor  e g  emacs  vim   not a word processor  when programming  You won t get this problem with a programming editor   PPS  For emacs users  M-x whitespace-mode will show the same info as cat -A from within an emacs buffer

Check if you mixed tabs and spaces  that is a frequent source of indentation errors

You can t mix tab and spaces for identation  Best practice is to convert all tabs to spaces   How to fix this  Well just delete all the spaces tabs before each line and convert them uniformly either to tabs OR spaces  but don t mix  Best solution  enable in your Editor the option to convert automagically any tabs to spaces   Also be aware that your actual problem may lie in the lines before this block  and python throws the error here  because of a leading invalid indentation which doesn t match the following identations
