# 16. Multiple Lists

#1

Oops, try again. "19" was printed instead of "30".

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

#2

you only need one loop? then `a` will contain the values from list_a and `b` will contain the values of list_b, then you can just check if a is greater then a, if so, print a, else print b

#3

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 a < b in zip(list_a, list_b):
print b
else:
print a

``O/p -``

19
None

Error message:
Oops, try again. "19" was printed instead of "30".

I am not sure how 19 is getting printed instead of 30. Can you please explain.

#4

well, first you need a loop which uses zip to get values from both list. Then you need an if/else to determine which number is bigger, and print the right number

#5

still didn't work ,

Oops, try again.
"2" was printed instead of "3".

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

#6

`a` and `b` now contain values from the list, you can compare those.

no need for in list_a, list_b in your if condition
