As other pointed out, iterating through a list or range is often a far
more elegant way to do a loop than a C-style loop. But the C-style for
loop is just syntactic sugar for a while loop. In some cases, C-style
for loops can have an initializer, a set of conditions, and incrementer
parts that are all based on different variables. For example:
for (a=begin_func() ; x < 3 and sometest(b) ; i=somefunc() )
This highly illogical and contrived function could not be represented in
python with a simple "for x in blah" statement. Rather you have to
represent it in its true form, which is a while loop:
a=begin_func()
while x < 3 and sometest(b):
#do stuff
#loop body
i=somefunc()
In fact, the perl/c for loop of the form:
for (<initializer>;<condition>;<incrementer>)
always translates directly to:
<initializer>
while <condition>:
#loop body
<incrementer>
