# Multiple Lists

#1

I'm stuck at "Multiple lists" in the loops section.

The Instructions say:
"Compare each pair of elements and print the larger of the two."
and they give me the code that is commented below.

So I wrote this.
But it doesn't work !

``````"""
list_a = [3, 9, 17, 15, 19]
list_b = [2, 4, 8, 10, 30, 40, 50, 60, 70, 80, 90]

for a, b in zip(list_a, list_b):
"""

list_a = [3, 9, 17, 15, 19]
list_b = [2, 4, 8, 10, 30, 40, 50, 60, 70, 80, 90]

for a, b in zip(list_a, list_b):
if(len(list_a)>len(list_b)):
print list_b
else:
print list_a``````

But it doesn't work !

#2

`elements` means elements in the list, so have to compare 3 and 2, 9 and 4, 17 and 8. (compare the actual values inside the list with each other)

#3

Now I've written this, but it still doesn't work

``````list_a = [3, 9, 17, 15, 19]
list_b = [2, 4, 8, 10, 30, 40, 50, 60, 70, 80, 90]

for a, b in zip(list_a, list_b):
if(list_a[a]>list_b[b]):
print list_a[a]
else:
print list_b[b]``````

It says "IndexError: list index out of range"
How can I fix that ?

#4

Okay, I have already fixed it.
But thanks anyway !
