Program to Reverse a String in Python

Here we have defined a function and in the function we are reversing a string using for loop. The steps are as follows:
Step 1: Create a loop to read each character of the String one by one.
Step 2: Declare an empty String.
Step 3: Concatenate the read character at the beginning of the string.

# Program published on https://beginnersbook.com
# Python program to reverse a given String
# Using a user-defined function
def reverse(str):
    s = ""
    for ch in str:
        s = ch + s
    return s


# given string
mystr = "BeginnersBook"
print("Given String: ", mystr)

# reversed string
print("Reversed String: ", reverse(mystr))
