Trying to pass in the list of name and number from my contact python code but only save the very last input

I have tried but only get to save the last input and not all of the contact list. Any ideas on how to save them all. I have been trying different code as I have comment some out to try a different way but it only print the last input. I would like it to save a output file with the first save to save all the contact then if they add or update a contact to save it as a updated saved file like choice 7. But I only get it to save the last input. I still learning how python works and this is over my head.

You're looking for serialization, which is (usually) best left to libraries. The json library easily handles reading and writing dictionaries to a file.
To write a dictionary, take a look at json.dump():
with open("Saved_Contact_List.txt", "w") as f:
json.dump(contact, f)

If a user checks out 5 copies of book1 and returns 3 returns 2 and then returns 1 more it allows it even if it exceeds the original amount of copies

if you choose to return a book at the start of the program, without checking out any books,
then it won't allow the return (intended). So say the user wants to check out 5/10 copies of
book1. It checks them out and subtracts them from the copies on shelf. They choose to return
3 one day, and 2 another day. (For testing purposes) the day after that, they return another
copy of book1, which is more than they checked out. It appends it to the book1.borrow aka
num of copies. It should not allow the user to return more copies than the original numbr of copies. So this is what I have in my main module. I can add the class LibraryBook if
needed.
from LibraryBook import *

How to loop same variable with different result

Hi I've got a school project which requires me to code a program that asks a user for their details it will then ask what them what size pizza they want and how many ingredients. It will then ask if they want another pizza. It will repeat this until they say no or they have six pizzas.
I don't really know how to explain my issues but I don't know how to loop the code so it asks for another pizza and each one has a different size and amount of toppings. I also don't know how I would print it.
Sorry if this is asking a lot or its confusing to understand or if the code is just painful to look at ahaha.
Thanks in advance.
CustomerName = input("Please input the customers name: ")
CustomerAddress = input("Please input the customers address: ")
CustomerNumber = input("Please input the customers number: ")
while True:
PizzaSize = input("Please input pizza size, Small/Medium/Large: ")
try:
PizzaSize = str(PizzaSize)
if PizzaSize == "Small" or "Medium" or "Large":
break
else:
print("Size not recognized")
except:
print("Invalid input")
if PizzaSize == "Small":
SizeCost = 3.25
elif PizzaSize == "Medium":
SizeCost = 5.50
elif PizzaSize == "Large":
SizeCost = 7.15
print(SizeCost)
while True:
ExtraToppings = input("Any extra toppings, 0/1/2/3/4+ ? ")
try:
ExtraToppings = float(ExtraToppings)
if ExtraToppings >= 0 and ExtraToppings <= 4:
break
else:
print("Please insert a number over 0")

print("Input not recognised")

ToppingCost = 2.00
elif ExtraToppings >= 4:
ToppingCost = 2.50

First of all, you should put the code from the second while loop in the first. There is no need for two while true loops. Then instead of
while True:
just put
pizza_count = 0 # how many pizzas they have
wantsAnotherPizza = True
while pizza_count < 6 and wantsAnotherPizza: # while they have less than 6 pizzas and they want another one
pizza_count += 1 # increase pizza_count as they order another pizza
# ... your code here from both of the while loops
x = input("Do you want another pizza? (Y/N)")
if x == "N" or x == "n":
global wantsAnotherPizza
wantsAnotherPizza = False:

You can modify your code like this. I thing you can simply your conditionals by using dictionaries. Try this
from collections import defaultdict
customer_order = defaultdict(list)
customer_order['CustomerName'] = input("Please input the customers name: ")
customer_order['CustomerAddress'] = input("Please input the customers address: ")
customer_order['CustomerNumber'] = input("Please input the customers number: ")
pizza_size ={
'small':3.25,
'medium': 5.50,
'large': 7.15
}
toppins= {'1': 0.75,
'2':1.35,
'3':2.00,
'4':2.50,
}
order = int(input("How many orders would you like to make: "))
while order:
PizzaSize = input("Please input pizza size, Small/Medium/Large: ").lower()
ExtraToppings = input("Any extra toppings, 0/1/2/3/4+ ? ")
try:
if PizzaSize in pizza_size:
size_cost= pizza_size[PizzaSize]
if ExtraToppings:
ToppingCost= toppins[ExtraToppings]
else:
print("Number not recognized")
continue
customer_order['order'].extend([{'size':PizzaSize,'toppings': ToppingCost}])
order -= 1
else:
print("Size not recognized")
continue
except Exception as msg:
print("Invalid input", msg)
continue
else:
print('Your order is complete')
print(customer_order)

When I print my list instead of using the names in the list the output shows the index numbers. Python 2D-Lists

Here is my code the lists are where Im having issues. Im new to python and I do not understand how 2D-lists work but I need to add then in to the program for a grade. Any help will be appreciated.

Your Order Contains 7 items for total of 10.5
Under name there should be a name of a girl Scout Cookie and not the index number, how do i fix this?
Many Thanks.

When you print the order in disp_order() you should print from cookie_list[c] in the second column. And print the whole item instead off just the first letter.
print("{}.\t{}\t{}\t{}".format(c+1, cookie_list[c], order_list[c][1], price))
The cookie names are not of equal length, so you'll have to adjust for that.

Storing Every Single Inputs and Then Displays In Order

Is there actually a way to store every different input for n number of inputs and then displays all of them all together in correct order for example:
The User Inputs Record Number, Name, Employee Type, Number Of Days Worked For n number of users
After n number of users, it displays the following all at once:
Record Number: 1
Employee Name: Alexander
Employee Type: C
Days Worked:5
Pay(RM):2500.00
Record Number: 2
Employee Name: Bella
Employee Type: V
Days Worked:10
Pay(RM):1000.00
Record Number: 3
Employee Name: Tom
Employee Type: S
Days Worked:20
Pay(RM):5000.00
Or is it only possible to display one by one? Here is my current code
print("{0:^15s}{1:^25s}".format("Employee Type", "Employee Rate (per day)"))
print("{0:^15s}{1:>15s}".format("C", "RM 500.00"))
print("{0:^15s}{1:>15s}".format("S", "RM 250.00"))
print("{0:^15s}{1:>15s}".format("V", "RM 100.00"))

You need to store the data somewhere, as you are receiving it. I would suggest a list (https://docs.python.org/2/tutorial/datastructures.html#more-on-lists) of dicts (https://docs.python.org/2/tutorial/datastructures.html#dictionaries) might be appropriate for your case. Then you can iterate over the list after you're done (in order to print).
