Reverse a Number in Python: 2 Easy Methods

In Python, you can reverse a number using the following methods:

Option one: Utilize string reversal.

  1. Convert the numbers into strings.
  2. Reverse the string using slicing functionality with strings.
  3. Convert the reversed string into an integer.

Example code:

num = 12345
reversed_num = int(str(num)[::-1])
print(reversed_num)

Option 2: Utilize loops and modulo operations.

  1. opposite_num
  2. opposite number
  3. Divide the original number by 10 to remove the last digit.
  4. Repeat steps 2 and 3 until the original number becomes 0.
  5. num reversed

Example code:

num = 12345
reversed_num = 0

while num > 0:
    reversed_num = reversed_num * 10 + num % 10
    num = num // 10

print(reversed_num)

The reversal of numbers can be achieved through methods such as string reversal or looping with modulo. The choice of method depends on personal preference and needs.
