If you are really asking whether assignment was deliberately designed as 
a statement rather than an operator, the answer is "yes".

http://www.python.org/doc/faq/general.html#why-can-t-i-use-an-assignment-in-an-expression

Note also that the Python alternative is now rather out of date: rather 
than writing

while True:
     line = f.readline()
     if not line:
         break
     ...do something with line...

We would nowadays write

for line in f:
     ...do something with line...

which seems to feel quite natural to most Python programmers.
