No it doesn't. Here is the definition of a block, it clearly mentions
indentation:

block:
     |  NEWLINE INDENTstatements  DEDENT
     |  simple_stmts But you are correct that python in not a context-free 
language. But so is any programming language. Yet a lot of those non 
context-free language designers thought it helpful to have a 
modified/extended BNF description of a superset of the intended language 
and used other means to further check whether the code in question was 
valid or not. -- Antoon Pardon
