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:

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.

It's my RPG assignment for our school. I made an RPG program about an encounter with a Pirate and conversing with him with a guessing game. When I didn't use Colorama, the program runs normal but when using it, it slows down the program when running. I submitted the got 18 or 20 which is not bad, and I suspected it's how my program runs that's why I didn't get the perfect score.
I'm wondering if you guys can help me how to run the program faster when using Colorama? I just really wanted to learn how to solve this kind of issue.

I am writing a program (for no specific purpose), where I take orders from users, which run the program. At some point, I ask them if they are happy with their decision. They have the option to "say" Yes or No. If their answer is no, I need the program to loop back to a specific point in the code. How can I do that?

I am new relatively new to the coding scene.
Thank you in advance for any answers.
You can wrap your code inside a while loop:
while True:
// your code
// at some point in the code:
happiness = input("Are you happy?")
if happiness == "yes":
break
To go to a specific point in the code, you will have to use this pattern (or something similar) several times.
You can use break statement to stop the(infinite)loop while continue is used to skip something that is what you're looking for here.
So, your code needs to be like this
# User deciding if she/he is happy with her/his decision
while True:
decision = input("\nYou chose "+". Are you happy with your decision? ").lower()
if decision == 'yes':
additional = input("Great! Would you like to order anything else? ").lower()
if additional == "yes":
what = input("What else would you like to order (menu, drink or both)? ").lower()
if what == "menu":
print("I understand. The program will return you to the menus.")
elif what == "drink":
print("I understand. The program will return you to the drinks.")
elif what == "both":
print("I understand. The program will return you back to the menus (no orders until now will be lost).")
break
elif additional == "no":
print("Awesome! The program will now summ up your price. Please wait a moment...")
time.sleep(2)
break
elif decision == "no":
continue
I'm kinda stuck on something. Well, alot of things but one step at a time right. I'm not sure how to get the program to add the choices that the user input together. The assignment asks me to make a vending machine that gets a users input, return the total to them when they input 0 to quit, then it will ask them to enter the money to pay, if it is a valid amount, it will dispense change, if not, it will ask for more money. Right now though, I'm stuck on it returning the user choices and adding the total together. I will paste my code below. thanks
def main():
userchoice = ()
while userchoice != 0:
# First, the vending machine will display a message on its "screen"
print("Welcome to the Vending Machine!")
# Now, the vending machine will display the available items
Options()
# Now, the first input will ask the user to enter their choice
userchoice = float(input("Please enter the number corresponding to your preferred item or 0 to quit: "))
# Now, the program will print the choice and re-run it until the user selects 0
choices = []
choices.append(userchoice)
if userchoice == 1:
print("You selected one can of Dr.Pepper for $1.50")
elif userchoice == 2:
print("You selected one can of Mtn.Dew for $1.50")
elif userchoice == 3:
print("You selected one bottle of Water for $1.00")
elif userchoice == 4:
print("You selected one bag of Doritos for $1.75")
elif userchoice == 5:
print("You selected one Snickers bar for $1.50")
elif userchoice == 6:
print("You selected one pack of Gum for $0.50")
elif userchoice == 0:
print(choices)
else:
print("Invalid Choice, Please Try Again")
def Options():
print("\t1. Dr.Pepper - $1.50\n"
"\t2. Mtn.Dew - $1.50\n"
"\t3. Water - $1.00\n"
"\t4. Doritos - $1.75\n"
"\t5. Snickers - $1.50\n"
"\t6. Gum - $0.50")
def Sum(userchoice):
return userchoice + userchoice
main()
I have discovered one problem which is that when you declare choices you declare it inside the loop, meaning it becomes [] each time the user picks something.
Try this:
def main():
choices = []
userchoice = ()
while userchoice != 0:
# First, the vending machine will display a message on its "screen"
print("Welcome to the Vending Machine!")
# Now, the vending machine will display the available items
Options()
# Now, the first input will ask the user to enter their choice
userchoice = int(input("Please enter the number corresponding to your preferred item or 0 to quit: "))
# Now, the program will print the choice and re-run it until the user selects 0
choices.append(userchoice)
if userchoice == 1:
print("You selected one can of Dr.Pepper for $1.50")
elif userchoice == 2:
print("You selected one can of Mtn.Dew for $1.50")
elif userchoice == 3:
print("You selected one bottle of Water for $1.00")
elif userchoice == 4:
print("You selected one bag of Doritos for $1.75")
elif userchoice == 5:
print("You selected one Snickers bar for $1.50")
elif userchoice == 6:
print("You selected one pack of Gum for $0.50")
elif userchoice == 0:
print(choices)
else:
print("Invalid Choice, Please Try Again")
def Options():
print("\t1. Dr.Pepper - $1.50\n"
"\t2. Mtn.Dew - $1.50\n"
"\t3. Water - $1.00\n"
"\t4. Doritos - $1.75\n"
"\t5. Snickers - $1.50\n"
"\t6. Gum - $0.50")
def Sum(userchoice):
return userchoice + userchoice
main()
This means that the choices variable now has something useful in it.
Here is a more refined approach, it always helps to see different design concepts:
options = {
'1': {'title':'Dr.Pepper','price':1.50},
'2': {'title':'Mtn.Dew','price':1.50},
'3': {'title':'Water','price':1.00},
'4': {'title':'Doritos','price':1.75},
'5': {'title':'Snickers','price':1.50},
'6': {'title':'Gum','price':0.50}
}

else:
print('Invalid Choice, Please Try Again')
print('Your Cart Contains:')
for each in sorted(choices):
print(each)

return choices, amount

creating a pizza ordering program for IT class, almost finished with it but I'm currently stuck with a problem that I can't seem to fix or don't know how to. As the user is finished choosing their pizza it was suppose to add up the total cost of the pizza they have chosen but the problems is they don't add up the instead the price stays the same

So I went and replace it with 'cost=+customerOrder[i][1]' but even then it somewhat works with the names of the pizza being added but not the prices unto the customer details.

The intended goal was, as the user input there choice one by one it takes out the name and places the price into the cost list but it doesn't seem to do that.

Also why I only have one list? it is because I was required to only use one
Code Issues:
For addition assignment the syntax is:
x += y # this assigns x to (x + y)
Not:
x = +y # this assign x to y
Glbols are not causing a problem in your code, but are usually frowned upon and negatively reflect on programming skills i.e. Why are Global Variables Evil?.
