I disagree it is very easy.

1) make sure you editor is set to inset 4 spaces rather than tab when 
pressing the tab key. consistency in your own code is now not an issue.

2) when importing code from someone else a simple search & replace of tab 
with 4 spaces will instantly correct the formatting on code using tab 
without breaking code that doesn't.

that is fixed by setting your environment consistantly but step 2 above 
will fix it if you forget.

Read pep 11 & always use 4 spaces for indentation not tab.

no more than failing to close a brace in a C like language
indentation is the syntax of python you will grow to love it, like most 
people I found it distracting at first even though i tended to indent 
other code (inconsistently)to make it readable.
