Hi, I'm working on this question:

Write a program to generate at random a ticket for Lotto 6-49. This should be six numbers between 1 and 49 (remember, no duplicate numbers!). Store the numbers in a list. The program should also include an option to generate a ticket in which the user can specify some of the six numbers and the program generates the rest. The program should also include an option to generate a ticket in which the user can forbid some of the six numbers.

I'm almost done and my problem is i'm having trouble in limiting the lotto_add and lotto_forbidden functions so that they only run a maximum of 6 times so that my lottery number list will at most contain 6 numbers as the question suggests. Thank you for your time

Code:

import random
def lotto_add():
picks=[]
user_add=str(input('Would you like to specify some of the six numbers? Enter "Y" for yes and "N" for no: ' ).strip())
while user_add=='Y' or user_add=='y':
user_num=int(input('Enter a number: ').strip())
while user_num in picks:
print('You cannot pick the same number twice. Please enter a different number: ')
user_num=int(input('Enter a number').strip())
user_add=str(input('Would you like to enter another number? Enter "Y" for yes and "N" for no: '))
picks.append(user_num)
return picks
def lotto_forbidden():
forbidden=[]
user_forbid=str(input('Would you like to forbid some of the six numbers? Enter "Y" for yes and "N" for no: ' ).strip())
while user_forbid=='Y' or user_forbid=='y':
user_num=int(input('Enter a number: ').strip())
while user_num in forbidden:
print('You cannot pick the same number twice. Please enter a different number: ')
user_num=int(input('Enter a number').strip())
user_forbid=str(input('Would you like to enter another number? Enter "Y" for yes and "N" for no: '))
forbidden.append(user_num)
return forbidden
def lotto(picks,forbidden):
a=6-len(picks)
for i in range (0,a):
num=random.randint(1,49)
while num in picks and num in forbidden:
num=random.randint(1,49)
picks.append(num)
return picks
