I am new in python and I was wondering the following. I have two matrices g1 and g2 and I would like to run a for loop for all the values of g1 and then g2.
I initially thought I could do:
for A in g1:
.....
for A in g2:
.....
But I was wondering if there is a way to run both at the same for loop. Eg. I tried this but it didn't work
for A in g1,g2:
You can use zip to iterate both iterables at the same time:
l = [1, 2, 3]
l2 = [4, 5, 6]
for x, y in zip(l, l2):
print x, y
1 4
2 5
3 6
zip() function returns a list of tuples, where the i-th tuple contains the i-th element from each of the argument sequences or iterables. The returned list is truncated in length to the length of the shortest argument sequence.
You can use zip() to iterate on two lists at once.
one = [1,2,3,4]
two = [5,6,7,8]
for elem1, elem2 in zip(one, two):
print(elem1, elem2)
Prints out this:
(1, 5)
(2, 6)
(3, 7)
(4, 8)
First, you should check the two data in the two loop is independent. Then you could merge the two loop in one.
