First Python Program
So I started learning python some weeks ago and I created a program based on what I’ve learnt so far. So it’s a program that does age verification. What do you think about this??

Cool. You just need to do something with order inputs of 0 or less, as others have already mentioned. Great job.

Data is in real life never stored in the program memory. It must be persistant, if that is the correct word. A way, is to create a light SQL database, connect with python to it, create a receipt, that stores and prints it. That is a real life scenario. Useful.
A possible next step.

Yeah I’ll improve the program as time goes on. A gui with more features and connects to a DB

I bet this wont be anybody's first program 😅

Okay let me say first proper program.. I created ones just using print statements and if clauses but no good logic.

Awesome! I just started and just using print and inserting comments. What course, book, site, are you using?

I think the try,except block in your while loop would exit the program if the user enters an invalid number.. that means you’d have to restart from the beginning (input user into, re-select drink, then input value).. is that how you’d like to handle that situation?

I would do a list with the bars menu, so they can choose instead of having to sanitize user input!

u/jaybee_4real Sep 15 '25
Yeah that’s good so the user sees the drinks available and selects them.. I’ll be making a gui for the program so the drinks will be displayed for the user to click

Very cool, packaging it as part of a mobile app or in a Tkinter gui for self checkout style touch screen at a bar?

u/jaybee_4real Sep 14 '25
I would like to make a gui for it but I’m yet to learn Tkinter

u/Anti-Hero25 Sep 14 '25
I mean, not to be THAT guy… but could drop your .py file in GPT5 and ask it to slap on a tkinter gui…. Run it , and dissect it , learn it that way. 🤷🏻♂️ That’s been my main method of learning how python works

This quite looks good and organized. However it seems that it can only make an order of the same drink.
You can further expand your program with more functionalities:
request different drinks in the same order.
make modifications to the current order.
read the menu from a json file (or a text file) instead of being hardcoded.
Also, depending on the target user (client or waiter), you can add the possibility of adding orders for a specific tables, and submit those orders to the "kitchen". Perhaps add the ability to view the total value of a given table.

I would put item check before quantity, or make it a singular input statement (like "5 beer" or "beer, 5"), which would need some parsing.

Very interesting. As a first program it is all good. But don't stop there, try to enhance it even more. For example you can handle the case when a user enters 0 or below beers.
Make the purchased items in lower case using .lower(), better for readability.
Capitalize the first letter of the first name and last name.
Handle empty input fields as well where a user must enter a string of size >=1
Maybe implement GUI, it is also a good addition.
But of course, step by step. And through each step try to understand example what the feature does. Keep practicing and enjoy!

Somehow I'm sure this isn't your first Python program 😏 Usually beginners start with programs without functions or methods, just basic prints and inputs. But here you already have def, dictionaries, try/except - definitely not your first step.

something I didn't see anyone mentioning above: I think I'd be good practice to test the age at the input, I'll save some teen a good 10 seconds of filings lol

u/Diamanthau Sep 20 '25
I see using def that’s not necessary because it’s only used one place. Did u do it for practice?

Create functions for everything and have a single main() function call the whole logic. Like:
def main(): ....
if name == "main": main()

Or put .lower() on the input
2
u/unsettlingideologies Sep 16 '25
Couldn't you use .title to capitalize the first letter only? So it would match the menu?
3
u/Leading-Concept- Sep 16 '25
Right yeah, if you use .lower() you would have to put the menu all in lowercase, if you use .title you can keep the menu as it is now!
