How can I restart my python 3 script?

Question

I am making a program on python 3. I have a place that I need the script to restart. How can I do this.

 #where i want to restart it
name= input("What do you want the main character to be called?")
gender = input("Are they a boy or girl?")

if gender == "boy":
    print("Lets get on with the story.")
elif gender == "girl":
    print("lets get on with the story.")
else:
    print("Sorry. You cant have that. Type boy or girl.")
    #restart the code from start

print("Press any key to exit")
input()

It's a general question about programming an not specific to Python ... by the way you can shorten your code with the two conditions on boy and girl...

while True:
    name= input("What do you want the main character to be called?")
    gender = input("Are they a boy or girl?")

    if gender == "boy" or gender == "girl":
        print("Lets get on with the story.")
        break

    print("Sorry. You cant have that. Type boy or girl.")

print("Press any key to exit")
input()

Simple but bad solution but you get the idea. I am sure, you can do better.

while True:
    name= input("What do you want the main character to be called?")
    gender = input("Are they a boy or girl?")

    if gender == "boy":
        print("Lets get on with the story.")
    elif gender == "girl":
        print("lets get on with the story.")
    else:
        print("Sorry. You cant have that. Type boy or girl.")
        #restart the code from start

    restart = input("Would you like to restart the application?")
    if restart != "Y":
        print("Press any key to exit")
        input()
        break

Don't have the program exit after evaluating input from the user; instead, do this in a loop. For example, a simple example that doesn't even use a function:

phrase = "hello, world"

while (input("Guess the phrase: ") != phrase):
    print("Incorrect.") //Evaluate the input here
print("Correct") // If the user is successful

This outputs the following, with my user input shown as well:

Guess the phrase: a guess
Incorrect.
Guess the phrase: another guess
Incorrect.
Guess the phrase: hello, world
Correct

or you can have two separate function written over, It's same as above(only it's written as two separate function ) :

def game(phrase_to_guess):
return input("Guess the phrase: ") == phrase_to_guess

def main():
    phrase = "hello, world"
    while (not(game(phrase))):
        print("Incorrect.")
    print("Correct")

main()

Hope this is what you are looking for .
