loop through list backwards python

>>> a = ["foo", "bar", "baz"]
>>> for i in reversed(a):
...     print(i)
... 

or

>>> for i, e in reversed(list(enumerate(a))):
...     print(i, e)

a = ["foo","bar","baz"]
for i in range(len(a)-1,-1,-1):
  print(a[i])

for item in my_list[::-1]:
    print item
    

# Python3 code to demonstrate  
# backward iteration 
# using range(N, -1, -1) 
  
# Initializing number from which  
# iteration begins  
N = 6
  
# using reversed() to perform the back iteration 
print ("The reversed numbers are : ", end = "") 
for num in range(N, -1, -1) : 
    print (num, end = " ")
