 character will reveal the problems.

 I'm in favour of this policy. [http://www.python.org/dev/peps/pep-0008/
 "PEP 8"] states:


 Code lay-out


     Use 4 spaces per indentation level.

     For really old code that you don't want to mess up, you can continue
     use 8-space tabs.

   Tabs or Spaces?

     Never mix tabs and spaces.

     The most popular way of indenting Python is with spaces only.  The
     second-most popular way is with tabs only.  Code indented with a
     of tabs and spaces should be converted to using spaces exclusively.
     invoking the Python command line interpreter with the -t option, it
 issues warnings about code that illegally mixes tabs and spaces.  When
 using -tt these warnings become errors.  These options are highly

     For new projects, spaces-only are strongly recommended over tabs.
 Most editors have features that make this easy to do.
