🔒 my first progrom

[lapis flax]

i want to know what to do with python from here:

ABCD = input("what kind of conversion would you like: Farenheit to Celcius, KM to MI, USD to Euros, or KG to LBS (note it goes other way around to) (A)(B)(C)(D): ")

if ABCD.upper() == "A":
    F_OR_C = input("F or C: ")
    if F_OR_C.upper() == "F":
        TEMP = input("what temp: ")
        yes = float(TEMP) - 32
        conversion = yes / 1.8
        print("your anwser is: " + str(conversion))
        
    if F_OR_C.upper() == "C":
        TEMP = input("what temp: ")
        yes = float(TEMP) * 1.8
        conversion = yes + 32
        print("your anwser is: " + str(conversion))
        
if ABCD.upper() == "B":
    KM_OR_MI = input("KM or MI: ")
    if KM_OR_MI.upper() == "KM":
        DIST = input("what is the distance: ")
        conversion = float(DIST) * 0.62137
        print("your anwser is: " + str(conversion))
        
    if KM_OR_MI.upper() == "MI":
        DIST = input("what is the distance: ")
        conversion = float(DIST) / 0.62137
        print("your anwser is: " + str(conversion))
    
if ABCD.upper() == "C":
    U_E = input("USD or Euros: ")
    if U_E.upper() == "USD":
        amount = input("what is the amount: ")
        conversion = float(amount) / 1.20
        print("your anwser is: " + str(conversion))
        
    U_E = input("USD or Euros: ")
    if U_E.upper() == "EUROS":
        amount = input("what is the amount: ")
        conversion = float(amount) * 1.20
        print("your anwser is: " + str(conversion))
        
if ABCD.upper() == "D":
    KG_OR_LBS = input("KG or LBS: ")
    if KG_OR_LBS.upper() == "KG":
        weight = input("what is the weight: ")
        conversion = float(weight) * 2.2
        print("your anwser is: " + str(conversion))
    
    if KG_OR_LBS.upper() == "LBS":
        weight = input("what is the weight: ")
        conversion = float(weight) / 2.2
        print("your anwser is: " + str(conversion))

Here's how to format Python code on Discord:

```py
print('Hello world!')
```

These are backticks, not quotes. Check this out if you can't find the backtick key.

For long code samples, you can use our pastebin.

[feral latch]

which Python version are you working with?

[lapis flax]

3.0

[feral latch]

wow, that's like 15 years old?

[lapis flax]

oh uhm

[feral latch]

you should get 3.13

[lapis flax]

idk if its that or not

[feral latch]

well, run it and check?

[lapis flax]

how can i check

[feral latch]

like python, or if you're on Windows, py

[lapis flax]

yeah i have 3.13

[feral latch]

ok, you could improve the code with a match block

[lapis flax]

im using thonny ide

[lapis flax]

whats that?

[feral latch]

do fix your syntax highlighting in the first message btw

[lapis flax]

how 😭 im new to this

[feral latch]

do you know how to edit your messages?

[lapis flax]

yeh

[feral latch]

there's the info you need

[lapis flax]

ok got it

!code

@feral latch so where should i take my python knoledge from here?

[feral latch]

https://paste.pythondiscord.com/IAAQ

what do you want to do with it?

[lapis flax]

i want to master python

[feral latch]

and do what with it

[lapis flax]

than move to the next easiest language

[lapis flax]

uhm be able to make just about any text based program possible with python

[feral latch]

nobody can do that

[lapis flax]

also what does the match function do?

[feral latch]

it's a statement, not a function

[lapis flax]

oh whats it do?

[feral latch]

it basically picks the matching block and runs it

based on the "case" statements

[lapis flax]

what matching block?

just the one before it?

[feral latch]

here it chooses the appropriate "case" block based on the ABCD variable value

[lapis flax]

ooooohhhhh

ok

[feral latch]

it's a more elegant way to express your if...else blocks

and match does much, much more if you know how to use it

[lapis flax]

huh i may have research that

[feral latch]

learning the syntax of the programming language is important

[lapis flax]

what does the case block do?

[lapis flax]

i know some but idk wat tutorial to use

[feral latch]

[feral latch]

match...case go hand in hand

[lapis flax]

ok so case references match?

and how does it reference it?

[feral latch]

I don't understand your question

[lapis flax]

what does case do

[feral latch]

match picks the appropriate case block to continue execution of code in, based on the expression given to match

[lapis flax]

uhm i dont understand :/

in this context what is case doing

[feral latch]

the interpreter hits the line with match, ok?

then it looks at the value of ABCD

then it looks which case block match the value, and runs that block only

so if your input "B" when the script runs, where does the interpreter continue execution after line 3?

[lapis flax]

oh i understand it now so when abcd is defined if the case is (whatever the condition is) than it executes the code?

[feral latch]

🤦‍♂️

answer my question, maybe you did get it

[lapis flax]

yeah thats what i said

[feral latch]

which line does the execution continue in if the value of ABCD is B?

after line 3

[lapis flax]

line 18?

[feral latch]

correct

if none of the cases match, the execution continues after the match statement

[lapis flax]

ah so if i have a randomizer and none of my preset cases are met i can run other code?

[feral latch]

if you want a catch-all case block, it's customary to add a case _:

the _ is just a convention but it could be any named variable

this case block is only run if no others match

[lapis flax]

oh yeah i said that i think i get it now

so its a elif block?

[feral latch]

in its basic form, yes

but match...case can do so much more

[lapis flax]

like what

[feral latch]

well, it's still essentially an if...elif block, but you get some interesting syntactic sugar, like guards: case "A" if something == anything: ...

the guard (if) there only runs the block if the expression returns a truthy value

[lapis flax]

OH ok

[feral latch]

I can't claim to know all the ins and outs of match...case myself either, it's a relatively recent feature too

[lapis flax]

ok

[feral latch]

it took 3 full PEPs (Python Enhancement Proposals) to implement fully

most new features only require 1

[lapis flax]

oh

ok

[lapis flax]

@feral latch

can i dm u?

[feral latch]

please don't

[lapis flax]

ok

[feral latch]

I'm not inclined to give private advice

[lapis flax]

ok
