Question

Is there a way to make this pythonic.

the_list = [1,2,3,4,5]
for x in the_list
   y= get_handler(x)
   #do something with x and y

Basically is there a simpler way to put the get_handler in the for deceleration?

ideally something readable like:

for x, get_handler(x) in the_list:
    #do whatever

A working, but non readable solution:

the_list = [1,2,3,4,5]
for x, y in [(item, get_handler(item) for item in the_list )]:   
   # do something

No, “pythonic” means how normal python code would look like (see gnibbler’s answer: that is what “pythonic” is about).

If you want something that will do exactly what you want, you can do:

def zipMap(func, iterable):
    for x in iterable:
        yield x,func(x)

Then:

for x,y in zipMap(get_handler, the_list):
    ...

Do note that this doesn’t save you any typing at all. The only way it would save you typing is if you were using it for currying:

def withHandler(iterable):
    for x in iterable:
        yield x,get_handler(x)

In which case it does save you typing:

for x,y in withHandler(the_list):
    ...

Thus it might be reasonable if you happened to use it a lot. It would not be considered “pythonic” though.
