[hearty shoal]

I got this but its not what i wanted

[meager berry]

what do you want?

can you show an example

[hearty shoal]

example:
Name: "GTA5"
Exception: ".exe"

something like that

@meager berry

[solar flame]

That's called the extension, not the exception, btw

[ruby wigeon]

!os.splitext

uh sorry

sigh

[meager berry]

you can assign each part to a variable and print them separately

[hearty shoal]

oh

[ruby wigeon]

!d os.path.splitext

[hearty shoal]

thx

[wanton remnant]

os.path.splitext

os.path.splitext(path)```
Split the pathname *path* into a pair `(root, ext)` such that `root + ext == path`, and the extension, *ext*, is empty or begins with a period and contains at most one period.

If the path contains no extension, *ext* will be `''`:

```py
>>> splitext('bar')
('bar', '')
```  If the path contains an extension, then *ext* will be set to this extension, including the leading period. Note that previous periods will be ignored...

[ruby wigeon]

^ calling this function will help you get the file name separated from the ext

🤦‍♂️ which i see you're already doing

[solar flame]

What do you mean by "make them separated"?

[hearty shoal]

im already did that i think

[meager berry]

name, extension = os.path.splittext()

[ruby wigeon]

Yeah, i didn't actually look at your code first. My bad

[hearty shoal]

oh alr

so wait what do I need to do here

to make it work

[solar flame]

What exactly are you trying to do? What do you mean by "make them separate"?

[meager berry]

.

[hearty shoal]

so i got this

but i want to make it like that:
Name: "GTA5"
Extension: ".exe"

[ruby wigeon]

do this

[solar flame]

right, so you can use tuple unpacking to store them in separate variables, like this.

And then you can do separate prints with the name and extension variables

[hearty shoal]

where do i need to put that

[ruby wigeon]

What does your intuition tell you?

[hearty shoal]

umm

letme think

to the print?

guys im sorry if i look stupid, im kinda new in python

[solar flame]

Can you explain what a for-loop does? Okay if you can't

[hearty shoal]

not really

[solar flame]

Okay. The for-loop will execute all the code inside of it (in the case of the program you currently have, print(os.path.splittext(file_name))) over and over again, but each time it will change what file_name refers to, going thru the list_of_files.

[hearty shoal]

ohhh

[solar flame]

So like, the first time it'll be "GTA5.exe", then it'll be "GTA6.exe", then it'll be "Screenshot1.png", etc.

[hearty shoal]

yeah i understand now

[solar flame]

Right now what you're doing is using the splittext function each time, and you're just printing the output of the splittext function. It seems you want to be processing it a bit more.

Using name, extension = os.path.splittext(file_name) will create 2 variables (name and extension) which contain the name and the extension of the filename, respectively.

You can use those variables in separate print statements to get the output you're looking for

[hearty shoal]

mhm

now i understand

[solar flame]

Awesome!

[hearty shoal]

so the splittext does separate the name and the extension of the file right?

[solar flame]

What splittext really does is it returns a tuple with 2 items, one of which is the name, and the other is the extension. That's what's being printed in the version of the program in the screenshot.

[solar flame]

the syntax here unpacks that tuple into 2 separate variables that you can process separately

[hearty shoal]

so i need to put that in print()?

like that print(name, extension = os.path.splittext(file_name))?

[solar flame]

no, print just writes text to the console.

[hearty shoal]

right

so i dont understand how can i use this: name, extension = os.path.splittext(file_name)

[solar flame]

Can you explain what a variable is?

[hearty shoal]

yeah

example:
x = car

i dont really know how to explain that

[solar flame]

What do you expect this code to do?

x = "car"
print(x)

[hearty shoal]

car

[solar flame]

what do you expect this code to do?

x,y = "cat", "dog"
print(y)
print(x)

[hearty shoal]

cat, dog

[solar flame]

Not quite

Each print statement will print on a separate line

[hearty shoal]

oh

[solar flame]

And it prints y before x

[hearty shoal]

ohh right

so it will be :
dog
cat

[solar flame]

Exactly

name, extension = os.path.splittext(file_name) is doing the same thing, except it's a bit obscured.

The parts of print(os.path.splittext(file_name)), include

• print, which will write whatever is in-between the parentheses to the screen,
• os.path.splittext(file_name), which will evaluate (the first time) as ('GTA5','.exe')

If you use os.path.splittext(file_name) without the print, then you can do something else with ('GTA5','.exe').

[hearty shoal]

yeah

[solar flame]

And what we want to do is assign it to 2 separate variables

[hearty shoal]

right

[solar flame]

Do you know what to do once you have the 2 separate variables?

[hearty shoal]

not really

[solar flame]

Are you familiar with fstrings, which look like f"your number is {5}"?

[hearty shoal]

i did learn them but i cant really understand how they work

[solar flame]

Basically, python will try to parse whatever is inside the brackets, rather than just leave it raw like in an unprefixed string or a raw string.

So like,

x = "cat"
print(f"My favorite animal is a {x}")
``` will print "My favorite animal is a cat"

[hearty shoal]

ohhh

i undersstand now

[solar flame]

Cool, is that enough for you to solve your problem?

[hearty shoal]

yeah, thanks a lot

[solar flame]

My pleasure!
