I cant pick a choice after looping

def print_menu():
print('1. American')
print('2. Asian')
print('3. Indian')
print('4. Mexican')
print('5. French')
print('6. Italian')
print('7. Seafood')
print('8. Pizza')
print_menu()
menu = input('\nChoose where you want to eat from-->')
if menu == "1":
def american_menu():
print('1. Dempsey Burger Pub')
print('2. Redrock Canyon Grill-Wichita')
print("3. Cheddar's Scratch Kitchen")
print("4. Neighbors| Restaurant & Bar")
print("5. The Kitchen")
print("6. Firebirds Wood Fired Grill")
print("7. Chicken and Pickle")
american_menu()
american = input("\nChoose which American Restaurant--> ")
if american == "1":
print("\nCall Dempsey Burger Pub")
while True:
go_back = input("Will you like to try another menu option?: ")
if go_back == "Yes":
print_menu()
else:
print("We'll continue with your current choice")
break
so i tried looping it so it goes back to choose again from the Cuisines and moving on to where you want to eat but so far, it just asks the go_back, after i say yes...it keeps repeating the go_back again
any help will be appreciated. Thanks. i want it to loop back to the choices, pick the choice and sub-choice i selected rather than it just picking the choice and not do anything. Thanks again
NB:this is an assignment and i am stuck plus i had a list of the choices but couldnt post it due to the site.

Write a while loop for print_menu and change continue with break
def print_menu():
while True:
#Use 2 while loops if you want. But the loop you are using is not needed
while True:
go_back = input("Will you like to try another menu option?: ")
if go_back == "Yes":
print_menu()
break
else:
print("We'll continue with your current choice")
break
Second Option:
def print_menu():
while True:
#Just use "while" here instead of the second one
go_back = input("Will you like to try another menu option?: ")
if go_back == "Yes":
print_menu()
else:
print("We'll continue with your current choice")

You don't need to use a while True loop at all. It might cause problems with infinite looping. You can avoid it by calling a new function check_if_wants_to_order_again after a user has chosen his menu in print_menu().
def print_menu():
print('1. American')
print('2. Asian')
print('3. Indian')
print('4. Mexican')
print('5. French')
print('6. Italian')
print('7. Seafood')
print('8. Pizza')
menu = input('\nChoose where you want to eat from-->')
if menu == "1":
american_menu()
check_if_wants_to_order_again()
def american_menu():
print('1. Dempsey Burger Pub')
print('2. Redrock Canyon Grill-Wichita')
print("3. Cheddar's Scratch Kitchen")
print("4. Neighbors| Restaurant & Bar")
print("5. The Kitchen")
print("6. Firebirds Wood Fired Grill")
print("7. Chicken and Pickle")
american = input("\nChoose which American Restaurant--> ")
if american == "1":
print("\nCall Dempsey Burger Pub")
def check_if_wants_to_order_again():
go_back = input("Will you like to try another menu option? Enter \"Yes\" or \"No\":")
if go_back == "Yes":
print_menu()
else:
print("We'll continue with your current choice")
print_menu()

When you continue your loop, you're calling print_menu() again, but you aren't doing any of the other things that need to follow print_menu() in order to prompt the user to make another choice.
Give this a shot:
# Define the menus as dictionaries.
# The key is the number that the user will pick,
# the value is the selected item.
# Main menu -- pick a cuisine.
main_menu = {
"1": "American",
"2": "Asian",
"3": "Indian",
"4": "Mexican",
"5": "French",
"6": "Italian",
"7": "Seafood",
"8": "Pizza",
}
# American restaurant menu.
american_menu = {
"1": "Dempsey Burger Pub",
"2": "Redrock Canyon Grill-Wichita",
"3": "Cheddar's Scratch Kitchen",
"4": "Neighbors| Restaurant & Bar",
"5": "The Kitchen",
"6": "Firebirds Wood Fired Grill",
"7": "Chicken and Pickle",
}
# This dict maps each cuisine name to the appropriate submenu.
cuisine_menus = {
"American": american_menu,
# "Asian": asian_menu,
# "French": french_menu,
# ...
}
# This dict maps each restaurant name to its contact info.
contact_info = {
"Dempsey Burger Pub": (
"(316) 425-3831",
"https://www.dempseysburgerpub.com/"
),
"Redrock Canyon Grill-Wichita": (
"(316) 636-1844",
"https://www.redrockcanyongrill.com/"
),
# ...
}
def print_menu(menu):
"""Print a menu, e.g. '1. American'..."""
for k, v in menu.items():
print(f"{k}. {v}")
def contact_restaurant(restaurant):
"""Contact a restaurant. Raises KeyError if we don't have contact info."""
phone, website = contact_info[restaurant]
print(restaurant)
print(f"Phone: {phone}")
print(f"Website: {website}")
# maybe do something with website to open a browser? idk
# Interactive loop. Go through the menus in turn,
# and repeat when done or when they enter something invalid.
# Break the loop once they finish picking a restaurant.
while True:
# Main menu (pick a cuisine)
print_menu(main_menu)
pick = input('\nChoose where you want to eat from-->')
# Error checking for invalid picks.
if pick not in main_menu:
print("Please select one of the listed options.")
continue
cuisine = main_menu[pick]
if cuisine not in cuisine_menus:
# This happens if they picked something that was in main_menu
# but not in cuisine_menus yet because we haven't written that part.
print("Oops! Haven't implemented that one yet.")
print(f"Try {', '.join(cuisine_menus)}")
continue
# Now we have a valid main menu pick that we can continue with.
cuisine_menu = cuisine_menus[cuisine]
# Print the menu and ask them to pick an item from that.
print_menu(cuisine_menu)
pick = input(f"\nChoose which {cuisine} Restaurant--> ")
if pick not in cuisine_menu:
print("Sorry, not an option. Let's start over.")
continue
restaurant = cuisine_menu[pick]
if restaurant not in contact_info:
print(f"Oops, we don't have contact info for {restaurant}.")
print("Let's start over...")
continue
print(f"\nCall {restaurant}")
# Prompt them to start over. If they don't, break the loop.
pick = input("Will you like to try another menu option?: ")
if pick != "Yes":
print("We'll continue with your current choice")
break
# Now the user has picked a restaurant to contact,
# so go ahead and contact them.
contact_restaurant(restaurant)
Note that all of the interaction happens inside the while True loop. Any time there's a continue within that loop, it goes back to the print_menu(main_menu) at the start, and then continues from there.

How do you make sure that a while loop doesn't loop to a previous input?

My program is simple, even though it is long. It is just a shopping program that displays the user's budget after buying a food object. I am relatively new to Python so my code is pretty messy and needs a lot of work.
My problem is that my program keeps looping back to a previous input instead of the input just put in. An example is I go to a food section and buy a food object, then I leave the section in which the food product is. But when I try to leave my program by typing "Nothing," it goes back to the section which I last inputted. Here are some images for context.
Starting the program by inputting a budget
Going to a food section
Leaving the food section
The wrong loop (the main problem)
Here is the program. Its really messy so I am sorry if it is hard to read.
x = 50 #budget
y = 5 #small budget
#Item Prices
#desserts
candy_bar = 1
candy_bag = 2
ice_cream = 2
#Welcome to the store
print("Hello there, young laddie, young man, young boy! Welcome to the Normal Big Meal Grocery Store, where our store is your store! ;)")
#How much money do you want to spend today
budget = int(input("What is your budget today?")) # at the moment, i do not have a shopping cart
if budget <= y:
print("You literally can only buy like 5 candy bars. You don't have enough money! Go to the clearance store across the street!")
print("**You leave and go to the clearance store...")
exit() #you leave
elif budget <= x:
print("I guess you can buy something...But it's not enough for a big meal! You might need to go to the Normal Medium Meal Grocery Store!")
print("**You leave and go to the Normal Medium Meal Grocery Store...")
exit() #you leave
elif budget >= x:
print("Cool! We have lot of stuff for you to make into a big meal, perhaps even a giant one!!!")
print("**Takes you by the hand and leads you into the beautiful Normal Big Meal Grocery Store...")
#User input for food:
items = input("Do you want dairy, meat, vegetables, fruits, or desserts! Type ‘Nothing’ if you don’t want to buy anything...")
while True:
def all_items():
items = input("Do you want dairy, meat, vegetables, fruits, or desserts! Type ‘Nothing’ if you don’t want to buy anything...")
if items == ("Nothing"):
bye = input("Are you sure you don't want to buy anything? Yes or No?")

elif items == ("desserts"):
print("Here are our desserts!\n1. Candy Bar: $1.00\n2. $Candy Bag: $2.00\n3. $Ice Cream: 2.00")
dessert_items = input("What desserts do you want to buy? Type 'Nothing' if you don't want any...")
if dessert_items == ("Candy Bar"):
print("Are you sure you want to buy this?")
candybarQ = input("Yes or no?")
if candybarQ == ("Yes"):

else:
print("Umm. We don't have that...")
all_items()

items = input("Do you want dairy, meat, vegetables, fruits, or desserts! Type
‘Nothing’ if you don’t want to buy anything...")
while True:
Move the items = input() line below the while true: loop so that it asks it every time the loop iterates. Currently you're only asking once and then using that answer as the variable each time the loop starts which is why in this case it will always go back to desert.

How do you call on an attribute of a class, as if its a variable (in python)?

Im new to coding, and pretty confused by the concept of class 's and how to use them. Im making a zork game as a practice exercise and have the following as part of my code:
def buildCharacter():
return(Hero(input("What is your name, traveler? \n> ")))
class Hero(object): #creates class Hero, Hero has-a name and has-a health
def __init__(self, name, health=10):
self.name = name
self.health = health
Later in the code, if the player gets 'hurt' I want to be able to reduce health, until its 0 and they 'die'.
I tried doing:
self.health -= 5
if self.health <=0:
exit(0)
but that doesn't work, saying 'self' not defined. How do I call on self.health to change it?
Edit: Ive been told that the whole code should be posted, so here it is:
from sys import exit

have_sword = False
gate_unlocked = False

Define a method in your class named hurt and a getter for health, like this :
class Hero(object): #creates class Hero, Hero has-a name and has-a health
def __init__(self, name, health=10):
self.name = name
self.health = health
def hurt(self,damage):
self.health-= damage
def get_health(self):
return self.health
Then later in the code you can call these methods like this :
hero = Hero("mohsen")
hero.hurt(5)
if hero.get_health()<=0:
exit(0)

I believe this example gets at the question you asked.
class Hero:
def __init__(self):
self.health = 100
Jon = Hero()
Jon.health -= 20
print(Jon.health)
The print statement outputs: 80

What you tried would work in another method within your class Hero:
class Hero(object):
def __init__(self, name, health=10):
self.name = name
self.health = health
self.alive = True
def take_damage(self):
self.health -= 5
if self.health <= 0:
self.alive = False
def is_alive(self):
return self.alive == True
If you are trying to reduce the health of an object of type Hero, you need to do it via the object reference like this:
my_hero = Hero()
my_hero.take_damage()
print(my_hero.is_alive())
Or you can access self.health directly (but better to do it via a method like I showed above):
my_hero = Hero()
my_hero.health -= 5

I got this sample rpg text adventure game online and im trying to understand the codes so that i can use it as a reference to develop my own text adventure game in the future. However, i am currently facing the error "gold is not defined at line 121 and i suspect is cause by indentation error. Although this is the error im facing so far, i believed that are more mistakes in the codes which i am glad for anyone to point it out.Thanks!

From a quick glance at it. #gold = int(100) is commented out on line 1.
This causes a issue because it doesn't know what gold is. it isn't defined. remove the # before it.

Crude virtual shop project fails when selection item from dictionary

I am making a crude shop in a Python 3.x script as a small project ( I started coding two days ago ), and when my program attempts to subtract the value of the item selected by the user from the initial amount of money the user starts out with, the program crashes.
Note: balance(): function aims to display remaining amount of money yet, but is not finished yet.
How can I fix my code, and is there any other way to improve/optimize it? Also, if you give a solution, please assume I don't know what method you will be using, so please give context and explain what you are using and other applications it can be used in.

Shop catalog is defined as:
shopCatalog = { '1. MCM Backpack' : 790 , '2. Gucci Belt' : 450 , '3. Supreme Box Logo Tee' : 100 , '4. Louis Vuitton Trenchcoat' : 1600 , '5. OFF-WHITE windbreaker' : 1200 , '6. Balenciaga Sneakers' : 850 }
However, you are trying to access the key by number. Such as
shopCatalog[2] which doesn't exist as a valid key. A valid key would be
shopCatalog['2. Gucci Belt']
Instead, try a list of tuples. A list is better because the order is guaranteed. In a dict, even though you numbered your items, it may print out of order.
shopCatalog = [ ('MCM Backpack', 790), ('Gucci Belt' : 450) , ...]
If you want the first item, you can just access it by the index. If you want them numbered, again, just use the index (although for both, keep in mind it is zero-indexed so you may have to add on to print your numbering and subtract one to get the right item.
Also, there is a flaw in your logic here:
shopChoice == 1 or 2 or 3 or 4 or 5 or 6:
While people talk like that, coding doesn't work like that. Instead, you'd have to do:
shopChoice ==1 or shopChoice ==2 and so on. But skip all of that and just say:
elif 1 <= shopChoice <= 6:

The error is:
Traceback (most recent call last):

KeyError: 1
shopCatalog is a dictionary, so you can access its values using keys. The keys are '1. MCM Backpack', '2. Gucci Belt' etc. Not numbers.
If you want to access the first, second etc. values in a dictionary, you can use an OrderedDictionary in Python: https://docs.python.org/3/library/collections.html#collections.OrderedDict

Try the below code, now i think it will work:
import time
import sys
# Dictionary:
# Shop Catalog, with numbers for prices.
shopCatalog = { '1. MCM Backpack' : 790 , '2. Gucci Belt' : 450 , '3. Supreme Box Logo Tee' : 100 , '4. Louis Vuitton Trenchcoat' : 1600 , '5. OFF-WHITE windbreaker' : 1200 , '6. Balenciaga Sneakers' : 850 }
# Money Values/Variables:

initialMoney = 3000
# Functions:

def browse():
global initialMoney
print("Welcome to the Virtual Shop Catalog")
time.sleep(1)
print("Here is what is currently on sale (item:price): ")
time.sleep(1)
print(shopCatalog)
time.sleep(1)
print("Enter '4' to quit")
time.sleep(1)
# This loop is where you choose to either return to the main menu, or order items.
while True:
try:
shopChoice = input("Enter item of choice: ")
if shopChoice == 4:
print("Returning back to main menu...")
time.sleep(0.5)
mainMenu()
break
# This is supposed to reduce the value/price of the item from your inital amount of money (initalmoney) or balance
elif shopChoice in ('1','2','3','4','5','6'):
print(" Purchased 1 " + str(shopCatalog[[i for i in shopCatalog.keys() if str(shopChoice) in i][0]]) + " .")
initialMoney = initialMoney - shopCatalog[[i for i in shopCatalog.keys() if str(shopChoice) in i][0]]
break
elif shopChoice == 3:
print("You want to leave already...? Ok, have a good day!")
time.sleep(1)
break
else:
print("Invalid option. Please pick a choice from 1-6")
browse()
except ValueError:
print("Invalid option. Please input an integer.")
exit
# Balance and money in account:
# This loop allows you to check the money in your account:
def balance():
print("hi")
# Menu selection function:
# It gives the user a number of three options, and will only accept the three integers provided.
def mainMenu ():
time.sleep(0.5)
print("1. Browse shop catalog")
time.sleep(0.5)
print("2. Check remaining balance")
time.sleep(0.5)
print("3. Quit program")
while True:
try:
choice = int(input("Enter number of choice: "))
if choice == 1:
browse()
break
elif choice == 2:
balance()
break
elif choice == 3:
print("You want to leave already...? Ok, have a good day!")
time.sleep(1)
break
else:
print("Invalid option. Please pick a choice from 1-3")
mainMenu()
except ValueError:
print("Invalid option. Please input an integer.")
exit
# On startup:
# This is the startup code and messages
print("Welcome to my virtual shop!")
time.sleep(0.5)
print("What would you like to do?")
time.sleep(0.5)
mainMenu()
Your code didn't work because there are no such a key i.e 1 or 2 etc so i simply just check each key if shopChoice is in it, if it is, get the value of it, if it isn't, check the next one.
