python reverse int code example

Example 1: how to reverse a list in python

mylist
[1, 2, 3, 4, 5]

mylist[::-1]
[5, 4, 3, 2, 1]

Example 2: python range reverse

When you call range() with three arguments, you can choose not only 
where the series of numbers will start and stop but also how big the 
difference will be between one number and the next.

range(start, stop, step)

If your 'step' is negative and 'start' is bigger than 'stop', then 
you move through a series of decreasing numbers.

for i in range(10,0,-1):
    print(i, end=' ')
# Output: 10 9 8 7 6 5 4 3 2 1

Example 3: reverse a number in python

# Python string/number reverser
example_number = 12143
example_string = "Hello there"

def reverse(thing): 
    thing = str(thing) # convert it to a string, just in case it was a number
    list_of_chars = [char for char in thing]
    reversed_list_of_chars = []
    x = -1
    
    for char in list_of_chars:
      reversed_list_of_chars.append(list_of_chars[x])
      x += -1
    
    reversed_thing = ''.join(reversed_list_of_chars)
    
    return reversed_thing
    # Or alternatively do:
    print(reversed_thing)

# Run it by doing this
reverse(example_number)
reverse(example_string)

Example 4: reverse intergers in python

# Get the number from user manually 
num = int(input("Enter your favourite number: "))
 
# Initiate value to null
test_num = 0
 
# Check using while loop
 
while(num>0):
  #Logic
  remainder = num % 10
  test_num = (test_num * 10) + remainder
  num = num//10
 
# Display the result
print("The reverse number is : {}".format(test_num))
