Write a Python program for the following task:

Take a string entered by the user and check if it begins with the letter "a" or not. If it begins with "a", the user is prompted that it is the first name on the list. If it does not begin with "a", the user is prompted that the string does not begin with the letter "a".

string1 = input("Enter a string: ")
if string1.startswith("a"):
    print("It is the first name on the list")
else:
    print("The string does not begin with the letter a")

Enter a string: apple
It is the first name on the list

Enter a string: mango
The string does not begin with the letter a
