You can reverse a string in Python in multiple ways:

1. Using slicing (shortest and fastest)
s = "hello"
print(s[::-1])

2. Using reversed() with join
s = "hello"
print("".join(reversed(s)))

3. Using a loop
s = "hello"
res = ""
for ch in s:
    res = ch + res
print(res)

All of these output: "olleh"
