Python iterate over two lists simultaneously

foreach, iteration, list, python, python-2.7

Solution

You can use the `zip()` function to pair up lists:

for x, y in zip(a, b):

Demo:

>>> a = [1,2,3]
>>> b = [4,5,6]
>>> for x, y in zip(a, b):
...     print x, y
... 
1 4
2 5
3 6

Problem

Is there a way in python to forloop over two or more lists simultaneously? Something like ``` a = [1,2,3] b = [4,5,6] for x,y in a,b: print x,y ``` to output ``` 1 4 2 5 3 6 ``` I know that I can do it with tuples like ``` l = [(1,4), (2,5), (3,6)] for x,y in l: print x,y ```
