hi,

I am trying to learn python... I can't explain the difference beetween these
two programms, Fibonacci suites :


>>> a,b,c = 1,1,1
>>> while c<12:
...     print b,
...     a,b,c = b,a+b,c+1
...
1 2 3 5 8 13 21 34 55 89 144

and

>>> a,b,c = 1,1,1
>>> while c<12:
...     print b,
...     a=b
...     b=a+b
...     c=c+1
...
1 2 4 8 16 32 64 128 256 512 1024


how about the instructions on the same block ? I thought they could be on
the other lines... perhaps I don't understand a=b and b=a+b ?


thanks in advance.
