Python program to reverse a string

text = "Python"

# 1. slicing
print(text[::-1])

# 2. reversed() and join()
print("".join(reversed(text)))

# 3. loop
result = ""
for ch in text:
    result = ch + result
print(result)

Output:

How it works

• Slicing with step -1 goes through the string from the end.
• reversed() gives the characters in reverse order, and join() makes a string again.
• In the loop, every new character is added to the front of result.
