[petsc-dev] breakage with python2.2

[Barry Smith]

Previous: 6 PEP 278: Universal Up: What's New in Python Next: 8 PEP  
282: The
7 PEP 279: enumerate()
A new built-in function, enumerate(), will make certain loops a bit  
clearer. enumerate(thing), where thing is either an iterator or a  
sequence, returns a iterator that will return (0, thing[0]), (1,  
thing[1]), (2, thing[2]), and so forth.

A common idiom to change every element of a list looks like this:


for i in range(len(L)): item = L[i] # ... compute some result based on  
item ... L[i] = result
This can be rewritten using enumerate() as:


for i, item in enumerate(L): # ... compute some result based on  
item ... L[i] = result
