How can I send back the player to the first question when the answer is wrong? (python)

Question

print("Welcome")
begin = input ("Would you like to begin (yes or no) ? : ")
if begin == "yes":

print("")

print("Awesome, enjoy the quiz! Lets begin, Question 1 : ")

-----------------------------------------------
If the person says : "no", how can I make it so that it sends him back to begin without going onto the next question?

Answer 1

You could probably make something like:

def start():
print("This is the start of the quiz.")

start()
print("Question 1")
...

if question == wrong:
start()

This is all psuedo code as I don't really know any Python but you get the point.
