I'm trying to write a simple program, but I meet a problem that the program does not output the given variable "tax" in the end.
def main():
# define and initialize constants and variables
menu1 = 6
menu2 = 2.5
menu3 = 1.25
menu4 = 3.75
choose = total = 0
tax = total*0.06
# display welcome
print("Welcome to Yum Yum Snack Bar!")
try:
while choose != 5:
print("\nPlease choose from the following menu:")
print("1) Personal Pizza $6.00")
print("2) Pretzel $2.50")
print("3) Chips $1.25")
print("4) Hot Dog $3.75")
print("5) Exit ")
choose = int(input("\nEnter your choice here: "))
if choose == 1:
total += menu1
elif choose == 2:
total += menu2
elif choose == 3:
total += menu3
elif choose == 4:
total += menu4
elif choose == 5:
continue
else:
print("Invalid choice. Must choose 1 – 5. Try again.")
print("Current total: $",total)
except:
print("Invalid choice. Must choose 1 – 5. Try again.")
main()
print("Current total: $",total)
print("Sales tax: $",tax)
print("Total Bill: $",total+tax)
print("Have a nice day!")
main()
when you initialized tax, you gave it a value of 0 because total*0.06 at that point equaled zero.
python goes line by line so the variable "tax" didn't change its value for the whole code, you only changed "total".
so to get the tax, you should calculate it again.
print("Current total: $",total)
tax=0.06*total
print("Sales tax: $",tax)
print("Total Bill: $",total+tax)
print("Have a nice day!")
Here the value of total gets updated but the tax is calculated before the check as given below, hence tax will output tax = total*0.06 where initially total=0
Please try this:
def main():
# define and initialize constants and variables
menu1 = 6
menu2 = 2.5
menu3 = 1.25
menu4 = 3.75
choose = total = tax = 0
# display welcome
print("Welcome to Yum Yum Snack Bar!")
try:
while choose != 5:
print("\nPlease choose from the following menu:")
print("1) Personal Pizza $6.00")
print("2) Pretzel $2.50")
print("3) Chips $1.25")
print("4) Hot Dog $3.75")
print("5) Exit ")
choose = int(input("\nEnter your choice here: "))
if choose == 1:
total += menu1
elif choose == 2:
total += menu2
elif choose == 3:
total += menu3
elif choose == 4:
total += menu4
elif choose == 5:
continue
else:
print("Invalid choice. Must choose 1 – 5. Try again.")
print("Current total: $",total)
except:
print("Invalid choice. Must choose 1 – 5. Try again.")
tax = total*0.06
print("Current total: $",total)
print("Sales tax: $",tax)
print("Total Bill: $",total+tax)
print("Have a nice day!")
main()
I guess your problem is solved.Also start using python dictionary instead of using lots of if else statements
def main():
# define and initialize constants and variables
menu1 = 6
menu2 = 2.5
menu3 = 1.25
menu4 = 3.75
choose = total = 0
tax = total*0.06
# display welcome
print("Welcome to Yum Yum Snack Bar!")
try:
while choose != 5:
print("\nPlease choose from the following menu:")
print("1) Personal Pizza $6.00")
print("2) Pretzel $2.50")
print("3) Chips $1.25")
print("4) Hot Dog $3.75")
print("5) Exit ")
choose = int(input("\nEnter your choice here: "))
price_dict = {
1: menu1,
2: menu2,
3: menu3,
4: menu4
}
if 0 < choose < 5:
total += price_dict[choose]
else:
if choose == 5:
continue
else:
print("Invalid choice. Must choose 1 – 5. Try again.")
print("Current total: $",total)
except:
print("Invalid choice. Must choose 1 – 5. Try again.")
main()
tax = total*0.06
print("Current total: $",total)
print("Sales tax: $",tax)
print("Total Bill: $",total+tax)
print("Have a nice day!")
main()
Now your tax is always 0. You have to calculate the tax at the end. Like this:
def main():
# define and initialize constants and variables
menu1 = 6
menu2 = 2.5
menu3 = 1.25
menu4 = 3.75
choose = total = 0
# display welcome
print("Welcome to Yum Yum Snack Bar!")
try:
while choose != 5:
print("\nPlease choose from the following menu:")
print("1) Personal Pizza $6.00")
print("2) Pretzel $2.50")
print("3) Chips $1.25")
print("4) Hot Dog $3.75")
print("5) Exit ")
choose = int(input("\nEnter your choice here: "))
if choose == 1:
total += menu1
elif choose == 2:
total += menu2
elif choose == 3:
total += menu3
elif choose == 4:
total += menu4
elif choose == 5:
continue
else:
print("Invalid choice. Must choose 1 – 5. Try again.")
print("Current total: $", total)
except:
print("Invalid choice. Must choose 1 – 5. Try again.")
main()
print("Current total: $", total)
tax = total * 0.06
print("Sales tax: $", tax)
print("Total Bill: $", total + tax)
print("Have a nice day!")
main()

I was following along with a youtube video to a ATM using python and I got expected expression. I dont know how to fix it. line 32, 37 and 40.

You can't have an elif after an else. This is because else will capture all the remaining cases. Indentation, meaning spaces or tabs before the line is very important in Python.
Here is what I think you meant to write:
balance = 1000
print("""

1) BALANCE
2) WITHDRAW
3) DEPOSIT
4) EXIT
""")
while True:
option = int(input("Enter Transaction"))
if option == 1:
print ("Your Balance is", balance)
anothertrans = input("Do You Want to make another Transaction? Yes/No: ")
if anothertrans == "YES":
continue
else:
break
elif option == 2:
withdraw = float(input("Enter Amount To Withdraw"))
if (balance > withdraw):
total = balance - withdraw
print("Success")
print("Your New Balance is: ",total)
else:
print("Insufficient Balance")
elif option == 3:
deposit = float(input("Enter Amount To Deposit"))
totalbalance = balance + deposit
print("Sucess")
print("Total Balance Now is: ", totalbalance)
elif option == 4:
print("Thank You ForBanking With Dutch Bank")
exit()
else:
print ("No selected Transaction")

elif airline == 2:

# Here is where how many tickets are needed based on how many people are going on the flight.
passengers = int(input("How many people are joining for this flight? "))
if passengers == 1:
print("You have selected one passenger.")
elif passengers == 2:
print("You have selected two passengers.")
elif passengers == 3:
print("You have selected three passengers.")
else:
print("Maximum number of passengers for a single order is 3.")
# Here is the chance that you or someone is your group is under the age of 18, and can qualify for a 25% discount.
discount = str(input("Are you or any passengers under the age of 18? "))
if discount == "Yes":
print("Congrats you qualify for a 25% discount!")
elif discount == "yes":
print("If so how many?")
int(input(""))
print("Congrats you qualify for a 25% discount!")
else:
print("Confirmed, no one is under the age of 18")
ticket_cost = (ticket_price*discount* 0.25)
After getting all the information, you may compute the total price
ticket_cost = passengers * ticket_price
Taking into acount the under 18 part :
discount = input("Are you or any passengers under the age of 18? ")
passengers_under_18 = 0
if discount.lower() == "yes":
print("Congrats you qualify for a 25% discount!")
passengers_under_18 = int(input("If so how many?"))
else:
print("Confirmed, no one is under the age of 18")
ticket_cost = (passengers - passengers_under_18) * ticket_price + passengers_under_18 * ticket_price * 0.25
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
Name:Jack
Telephone:47347842
ORDER:
['2. Hawaiian pizza', 8.5]
['1. Pepperoni pizza', 8.5]
['3. Garlic cheese pizza (with choice of sauce)', 8.5]
Total Price: 8.50
Here's the price list that they have to choose from
['1. Pepperoni pizza', 8.5]
['2. Hawaiian pizza', 8.5]
['3. Garlic cheese pizza (with choice of sauce)', 8.5]
['4. Cheese pizza (with choice of sauce)', 8.5]
['5. Ham and cheese pizza', 8.5]
['6. Beef & onion pizza', 8.5]
['7. Vegetarian pizza', 8.5]
['8. BBQ chicken & bacon aioli pizza', 13.5]
['9. Boneless pizza (italian style anchovy with no bones)', 13.5]
['10. Pizza margherita', 13.5]
['11. Meat-lover’s pizza', 13.5]
['12. Tandoori pizza', 13.5]
I don't know if the problems lies in this code but it seem like it is. I originally I tried using 'cost.append' but it only came up with an error like this
unsupported operand type(s) for +: 'int' and 'str'
def Choice_of_pizza():
for i in range(1,pizza_no

while True:

pizza_kind = int(input("Choice of pizza(s):"))
if pizza_kind < 1:
print("Refer to PIZZA MENU for number order")
continue
if pizza_kind > 12:
print("Refer to PIZZA MENU for number order")
continue
else:
pizza = pizza_kind - 1 #Makes the list start at 1
cost.append(MENU[pizza_kind-1][0][pizza])

else: #Price stays the same if pick up
Combined_Total = total_cost
break
except ValueError:#Validating inputs - accepts only numbers and can't be left blank
print("Please use numbers only")

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.
def Choice_of_pizza():

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.

So I am trying to write a code that uses functions to create a menu for user input. It's basically just inputting the amount of dollars you wish and picking which currency to convert it to. I am absolutely lost because every time I attempt to run this code I have so far (Just to make sure I'm on the correct path), I input "1" and say 20 dollars just for example, it tells me that "dollars" is not defined when I clearly have it as a user input.
def DisplayMenu():
print("Choose a menu option:")
print("1. European Euro")
print("2. British Pound")
print("3. Mexican Peso")
print("4. Chinese Yuan")
print("5. Japanese Yen")
print("6. Quit")
selection = int(input("Enter your selection: "))
dollars = eval(input("Enter the dollar amount to convert: "))
def DollarConvert(selection, dollars):
if selection == "1":
conversion = dollars * 0.921
elif selection == "2":
conversion = dollars * 0.807
elif selection == "3":
conversion = dollars * 24.246
elif selection == "4":
conversion = dollars * 7.085
elif selection == "5":
conversion = dollars * 108.03
elif selection == "6":
quit
elif selection > 6:
print("Invalid input.")
DisplayMenu()
print("$ ",dollars," = ",chr(8364),conversion)
Hopefully someone can help me with this because I am out of ideas
You never run or from DollarConvert(), or receive outputs from either function. Change the functions to return values, like this:
def DisplayMenu():
print("Choose a menu option:")
print("1. European Euro")
print("2. British Pound")
print("3. Mexican Peso")
print("4. Chinese Yuan")
print("5. Japanese Yen")
print("6. Quit")
selection = int(input("Enter your selection: "))
dollars = eval(input("Enter the dollar amount to convert: "))
return selection, dollars
def DollarConvert(selection, dollars):
if selection == "1":
return = dollars * 0.921
elif selection == "2":
return = dollars * 0.807
elif selection == "3":
return dollars * 24.246
elif selection == "4":
return dollars * 7.085
elif selection == "5":
return dollars * 108.03
elif selection == "6":
quit
elif selection > 6:
print("Invalid input.")
return None
selection, dollars = DisplayMenu()
conversion = DollarConvert(selection, dollars)
print("$ ",dollars," = ",chr(8364),conversion)
There we go.
In your code, the dollars variable's scope is limited to inside that function. You have to return dollars from the function to make it accessible. Also your dollar convert function is never called, so you need to call it. You also need to add a return statement for the conversion variable. Returning is essential for most all functions, otherwise data is lost.
You could also do it using the global keyword
dollars = None
conversion = None
def DisplayMenu():
global dollars
print("Choose a menu option:")
print("1. European Euro")
print("2. British Pound")
print("3. Mexican Peso")
print("4. Chinese Yuan")
print("5. Japanese Yen")
print("6. Quit")
selection = input("Enter your selection: ")
dollars = int(input("Enter the dollar amount to convert: "))
DollarConvert(selection, dollars)
def DollarConvert(selection, dollars):
global conversion
if selection == "1":
conversion = dollars * 0.921
elif selection == "2":
conversion = dollars * 0.807
elif selection == "3":
conversion = dollars * 24.246
elif selection == "4":
conversion = dollars * 7.085
elif selection == "5":
conversion = dollars * 108.03
elif selection == "6":
quit
elif selection > 6:
print("Invalid input.")
DisplayMenu()
print("$ ",dollars," = ",chr(8364),conversion)
Also, one more mistake on line 12 & 13, i.e
selection = int(input("Enter your selection: "))
changed to
selection = input("Enter your selection: ")
and

Pretty much the title. Wrote some code but I don't know whats wrong with it as it won't run. I don't know if its even close to right. This program is a mac and cheese program, the user chooses between small, medium, and large and can add toppings. It has to spit out the toppings cost, base cost, and total cost with tax. I think I'm close, but I'm pretty fresh to this whole programming thing, so help a guy out. :)

You might find it helpful to start with a trimmed down version of your program and get that to work. Just maybe "small." Also, the "def menu()" function appears to be repeated for each size. You might find it easier to work with/debug if you just have one "def menu()" that works more generally. Lastly, you might want to watch out for "ints vs. strings" in your processing. Hope that helps troubleshoot.
