for loop in reverse order python code example

Example 1: python for loop backwards

for i in range(len(item)-1, -1, -1):
        print(item[i])

Example 2: reverse for loop python

# 1.
for i in reversed(range(3)): # output: 	0
    print(i)				 #			1
    						 # 			2
# works with arrays as well , reversed(arr)

# 2.
# another alternative is
arr = [1,2,3]
# note: arr[start : end : step]
for i in arr[::-1]:			 # output:	0
  print(i)					 # 			1
  							 #			2

# 3.
# last alternative i don't recommened!
# note: range(start, end, step)
for i in range(len(arr) - 1, -1 , -1): 	# output: 	0
  print(i)								# 			1
  										# 			2
# read more on range() to understand even better how it works has the same rules as the arrays

Example 3: how to count backwards in for loop python

# for i in range(start, end, step)
for i in range(5, 0, -1):
    print(i)
5
4
3
2
1

Example 4: print string in reverse order uing for loop python

# reversing a sring using recursion
def reverse_recursion(s):
    if len(s) == 0:
        return s
    else:
        return reverse_recursion(s[1:]) + s[0]

Example 5: python reverse for loop

rop = input('Type a three or more word or code.')
t = len(rop)
j = ''
for i in range(t-1,-1,-1):
  j = j+rop[i]
print(j)
