The following function named get_first_name that asks the user to enter his or her first name, and returns it as follows:

def get_first_name():
    firstName = input("Enter your first name: ")
    return firstName

Explanation:

• Create a function without any arguments called get_first_name.
• Inside the capability, we utilize the information capability to incite the client to enter their most memorable name.
• The firstName variable holds the input. In the end, the value of firstName is returned.
• The user will be prompted to enter their first name when the get_first_name function is called, and the value they provide will be returned as the function's output.
