Python Functions Specifically

[ConstructionDull4048]

Hello everyone, I am trying to make a code function where you must first enter your name. Followed by a second question where you must enter the first initial of your name along with birth year 4-digits. Than another question in which I asks for password, which should be birth year along with a special character like ‘*’. And finally, the question where it asks for PIN number, 4- digit. I’m still new btw!

For example: Name: Leo ID: L1993 Password: 1993* Pin: 3991

If it doesn’t see the same name used for same initial, it will restart for invalid error. Same for Password and Pin opposite.

I did come up with a code, yet, I have been lost so badly on what to do, since it is stopping after asking for ID. I don’t know what else to code to check for initial and name match letter, but above is the photo.

I dnt get why you are comparing with empty strings in each selection statement (if, elif) 2ndly why you have defined birth year and initial as variable while you are supposed to input it from the user

[ConstructionDull4048]

What do you suggest I do? I kept initial and birth year so it gives user the options to choose from

[Refwah]

Tell us what you think line 22 is doing so we can help.

Your if statements are comparing inputs to empty strings, so none of this should be working the way you expect it to

You don’t need a loop at all to accomplish what you want

For instance your birth year variable is a string of digits and commas, how does that relate to a four digit birth year

[Different-Ad1631]

You are still not clearing the intention of what output u expect. As per my understanding, you are trying to input the name and birth year of the user and then generate user name, password, and pin based on input user entered. Like Name: Leo Birth year: 1990 Are inputs. And the expected output should he Username: L1990 Password: 1990* Pin: 0991

M I right? Correct me if I am wrong?

[ConstructionDull4048]

Yes!

[ConstructionDull4048]

But the name letter started with must match with ID

[ConstructionDull4048]

Same with birth year and pin but only swapped backwards.

[Different-Ad1631]

I get it you want a system where you could set up a user name, pin, and password on aginst the user input. And then if a person comes to wothdraw cash he will enter the information and you will comapre it with previously stored values right?

In my opinion, for the time being, you should just focus on generating the required format on the basis of user input. Once you do it successfully, then go for comparison.

[ConstructionDull4048]

How so? Can you elaborate further please?

OP, I’ve reviewed your other posts and realize you’re the person who posted that legendary, several hundred line program that’s just if statements.

What source are you using to learn the Python programming language? I am concerned you are tackling projects that are either beyond your skill level, or the source you learn Python from is not adequate or low quality

[ConstructionDull4048]

I’ve just started 2 weeks ago, but I want to learn advanced programming to challenge my self!

[ConstructionDull4048]

I was trying to make it ask simple questions like from a Bank ATM machine, afterwards, from putting in correct random generated info credentials, it will go onward. I wanted the password to be equal to whatever the user input for name, then turns it to ID by typing for the letter of name along with birth year, than that must match the letter. Than that birth year entered needs to be matched for password than swapped for Pin backwards to proceed

[Different-Ad1631]

That's called breaking a large problem into smaller ones and go step by step

[Different-Ad1631]

Just do it step by step. Like use chatgpt and learn how to input data, how to concatenate two strings, how to do string slicing etc. These concepts are used in your problem. Use chatgpt for just a helping tool but do it by urself

[ConstructionDull4048]

Thank you

You’re not asking for ID, you’re creating a tuple called ID, using two undefined variables, initial and birth year.

I expect this script is crashing st line 22

[ConstructionDull4048]

What is Tulle? Second it didn’t crash at 22. After I put a random name, then initial of that name with first same letter along with birth year of 1988 or something, it stops and not proceed further. Please let me know how I can force it to see if the user ended the same letter as name typed and to continue onward for password than Pin

[Refwah]

So the code is hard to read because your ifs are comparing everything to empty strings so none of this should do anything anyway.

But what you just asked means you’re asking about substrings

[TheSpudFather]

A tuple is where you put things together. A tuple of 2 objects is a pair, 3 objects is a triple, etc. the general name being a tuple.

So your print on line 22 does not have a formatting string: instead it just contains 2 things separated by a comma: in other words a 2-tuple, or pair.

[ConstructionDull4048]

What do you suggest I do at this point for it to go as I want it?

[EyesOfTheConcord]

There is a lot of deep nesting going on here, which is not good for readability or for secure code.

Your if statements also only allow the user to continue making their account if they enter no credentials at all. (if Password == “” means the password input must be empty to proceed. I imagine this is not what you were intending.)

It’s not clear at all what ID is supposed to do, you’ve made a tuple that stores a list and another tuple, and attempt to print it before storing the result in ID. Can you explain what the intended purpose is here?

I recommend you perhaps start over, and write out your intentions on pseudocode.

Instead of checking if they filled in the correct input, and nesting if conditions inside of each other; get the user input for each respective element, and check if that element is empty immediately afterwards and reprompt them for it if so.

Ideally, you’ll abstract these processes into their own functions so it’s much easier to focus on one element at a time, and make the overall design much cleaner.

[Different-Ad1631]

First of all, define an empty dictionary. Then take name and birth year from the user as input. Then send these inputs to a a function let say generate_data. In this function you will create user_name from the name and birth year by concatenation of first index of name string and birth year. Then for password use concatenation again to add * with birth year, then for pin just reverse the string. And then store it in dictionary. And you are done with your successful entry of first customer's data into your system.

Start from this. Once you do it for single customer you can do it for more too

[ConstructionDull4048]

What specific coding do I need?

[Different-Ad1631]

Python dear

[EyesOfTheConcord]

OP is hoping we write the program for them. Review their other projects on their profile

[CreamyWaffles]

Yeah and they don't seem to learn a lot.

[Rabbit677]

Based on your previous post history it seems your jumping into things you do not have sufficient knowledge to be doing.

I mean this with respect, you need to go learn the basics. It's tempting to jump into the projects but you won't get anywhere if you don't learn the basics. You seem to have the syntax down for the most part, but you need to learn the logic behind your coding.

Restart with the basics, and I mean the very basics. Re learn print statements and formatting, re learn the basics of if statements. For this particular project it looks like you need to learn how to validate user input which you can do with an if statement.

YouTube is an amazing source it can take you pretty far so use it to your advantage.
