How do I loop through 2 arrays?

Question

I have 2 different arrays and I need help printing both of them

Route = ["Bus A","Bus B","Bus C","Bus D","Bus E","Bus F"]
DaysLate = [ [1],[2],[3],[4],[5],[6] ]

is there a way I can get this output?

Bus A 1
Bus B 2
Bus C 3
Bus D 4
Bus E 5
Bus F 6

Try this:

Route = ["Bus A","Bus B","Bus C","Bus D","Bus E","Bus F"]
DaysLate = [ [1],[2],[3],[4],[5],[6] ]

for i,j in zip(Route,DaysLate):
    print(i, j[0])

Try this:

for i in range(6):
    print(Route[i], DaysLate[i][0])

Will this work perfectly if the length of the list is greater than 6?

oh ok sorry it was because I forgot the indent, works

You can also use the function chain.from_iterable() from itertools module to chain all sublists into a single sequence:

for i, j in zip(Route, itertools.chain.from_iterable(DaysLate)):
    print(i, j)

Alternatively you can use a star * to unpack sublists:

for i, j in zip(Route, DaysLate):
    print(i, *j)
