Question 31) Write a Python Program to reverse a String.
Solution 1: Using Slicing
input_string = "Environment"
reversed_string = input_string[::-1]
print(reversed_string)
Output:
tnemnorivnE
Solution 2: Using for loop
input_string = "Python"
reversed_string = ""
for char in input_string:
reversed_string = char + reversed_string
print(reversed_string)
Output:
nohtyP
Solution 3: Using recurssion function
def recursion_reverse_string(input_str):
if len(input_str) == 0:
return input_str
else:
return reverse_string(input_str[1:]) + input_str[0]
reversed_string = recursion_reverse_string("Hello")
print(reversed_string)
Output:
