To get a new reversed list, apply the reversed function and collect the items into a list:
>>> xs = [0, 10, 20, 40]
>>> list(reversed(xs))
[40, 20, 10, 0]
To iterate backwards through a list:
>>> xs = [0, 10, 20, 40]
>>> for x in reversed(xs):
... print(x)
40

February 11, 2022 -
Hey, I'm learning lists in Python. When I try to use the reverse method to reverse my list it returns 'None'. I've read online that apparently this is because it doesn't actually change the list but I'm not sure what that means tbh. Even if it was a temporary modification, wouldn't it print that temporarily modified version of the list instead of printing 'None'? I found another solution (assuming the list is stored in my_list variable), print(my_list[::-1]). I understand that the -1 is referring to the end of the list (and maybe telling it to count back from there), but I have no idea what the '::' means. Would appreciate some help, thanks.

The way lists go in python is list[start_index:end_index:step]. By skipping the any of them they default to start_of_list:end_of_list:1. By doing ::-1, you're telling to go from the start of the list till the end by increasing the index by -1.

listVar = ['a','b','c','d']
def listReverse(list,start,end):
while(start<end):
temp = list[start]
list[start] = list[end] #Swaping
list[end]=temp
start+=1
end-=1
print(list)
listReverse(listVar,1,3)
Output : - ['a', 'd', 'c', 'b']
