To understand this example, you should have the knowledge of the following Python programming topics: ... num = 1234 reversed_num = 0 while num != 0: digit = num % 10 reversed_num = reversed_num * 10 + digit num //= 10 print("Reversed Number: " + str(reversed_num)) ... First, the remainder ...

There is no built-in function to reverse a String in Python. The fastest (and easiest?) way is to use a slice that steps backwards, -1. ... Create a slice that starts at the end of the string, and moves backwards.

country_capitals = { 'England': 'London', 'Canada': 'Ottawa', 'Germany': 'Berlin' } # access keys in reversed order # and convert it to a tuple country = tuple(reversed(country_capitals)) print(country)

November 18, 2025 - This method reverses the number by converting it to a string, slicing it in reverse order and converting it back to an integer. ... This method extracts digits from the end of the number using % 10 and builds the reversed number digit-by-digit.

July 31, 2023 - So far, you’ve learned about core Python tools and techniques to reverse strings quickly. Most of the time, they’ll be your way to go. However, you might need to reverse a string by hand at some point in your coding adventure. In this section, you’ll learn how to reverse strings using explicit loops and recursion. The final technique uses a functional programming approach with the help of Python’s reduce() function.
