Print function not printing anything

Question

Hi guys I'm trying to reverse my list here using a function. I don't know why my code isn't working. See the code below:
L=[1, 2,3,4]
def rev() :
L.reverse()
print(L)
#The code is running but not printing the reversed list. Please help.

Answer 1

you need to call the function at the end
L = [1, 2, 3, 4]
def rev():
L = L.reverse()
print(L)
rev()

Thanks much. It is working now. Have a blessed day
