'Reverse list using for loop

my_list=[1,2,3,4,5]
new_list=[]
for i in range(len(my_list)):
    new_list.insert(i,my_list[-1])
    my_list.pop(-1)

I used the above code to reverse a list but I was wondering why is the range(len(my_list)) necessary, more specifically, why doesn't it work if I simply put "for i in my_list:"?

Solution 1:[1]

List can be reversed using for loop as follows:

>>> def reverse_list(nums):
...     # Traverse [n-1, -1) , in the opposite direction.
...     for i in range(len(nums)-1, -1, -1):
...         yield nums[i]
...
>>>
>>> print list(reverse_list([1,2,3,4,5,6,7]))
[7, 6, 5, 4, 3, 2, 1]
>>>

Solution 2:[2]

#use list slicing 
a = [123,122,56,754,56]
print(a[::-1])

Solution 3:[3]

like this? 

new_list=[]

for item in my_list:
    new_list.insert(0, item)
    # or:
    # new_list = [item] + new_list

Solution 4:[4]

def rev_lst(lst1, lst2):

    new_lst = [n for n in range(len(lst1)) if lst1[::-1]==lst2]
    return True

Could this be correct solution?

Solution 5:[5]

The simplest way would be:

list1 = [10, 20, 30, 40, 50]


for i in range(len(list1)-1,-1,-1):

    print(list1[i])

Solution 6:[6]

lst = [1,2,3,400]
res = []

for i in lst:
    # Entering elements using backward index (pos, element)
    res.insert(-i, i)

print(res)
# Outputs [400, 3, 2, 1]
