What is Reverse a String?
Python slicing provides a concise way to read a sequence from the end to the beginning.
Reverse a Python string with slicing and run the example online.
When should you use it?
- Learn Python syntax through a practical example.
- Build a foundation for larger programming problems.
- Test an idea quickly without a local setup.
Example code
main.py
message = "CodeUtility"
reversed_message = message[::-1]
print(reversed_message)Expected output
ytilitUedoCHow it works
The slice [::-1] uses the complete string with a negative step, so the characters are returned in reverse order.
Change the values and run the program in the CodeUtility online Python compiler without installing Python locally.
Practice exercises
