Last update on April 19 2025 13:05:23 (UTC/GMT +8 hours)

Reverse a string.

Write a Python program to reverse a string.

Sample Solution:

Python Code:

# Define a function 'reverse_string' that takes a string 'str1' as input.
# The function returns the reversed version of the input string.
def reverse_string(str1):
    return ''.join(reversed(str1))

# Print an empty line for spacing.
print()

# Call the 'reverse_string' function with the input "abcdef", reverse the string, and print the result.
print(reverse_string("abcdef"))

# Call the 'reverse_string' function with the input "Python Exercises.", reverse the string, and print the result.
print(reverse_string("Python Exercises."))

# Print an empty line for spacing.
print()
