Python iterate over two lists simultaneously
提问by user80551
Is there a way in python to forloop over two or more lists simultaneously?
python中有没有办法同时对两个或更多列表进行forloop？
Something like
就像是
a = [1,2,3]
b = [4,5,6]
for x,y in a,b:
print x,y
to output
输出
1 4
2 5
3 6
I know that I can do it with tuples like
我知道我可以用元组来做到这一点
l = [(1,4), (2,5), (3,6)]
for x,y in l:
print x,y

You can use the zip()functionto pair up lists:
您可以使用该zip()函数来配对列表：
for x, y in zip(a, b):
Demo:
演示：
>>> a = [1,2,3]
>>> b = [4,5,6]
>>> for x, y in zip(a, b):
... print x, y
...
1 4
2 5
3 6
