Question

write a Python program to read a string and display it in reverse order​

Answer 1

Answer:

Strings can be reversed using slicing. To reverse a string, we simply create a slice that starts with the length of the string, and ends at index 0. The slice statement means start at string length, end at position 0, move with the step -1 (or one step backward).

Answer 2

Required Answer:-

Question:

• Write a Python program to read a string and display it in reverse order.

Solution:

There are different approaches of solving this problem.

1. Using loops.

s=input("Enter a string: ")

for i in range(len(s)-1,-1,-1):

print(s[i],end="")

2. Using string slicing.

s=input("Enter a string: ")

print(s[::-1])

3. In one line.

print(input("Enter a string: ")[::-1])

If you know slicing, you can use second or third approach and if you don't know slicing, follow the first approach.

Explanation of First Approach: Ask the user to enter the string. Iterate 'i' in the range (length_of_string - 1) to 0. Display all the characters in ith index.
