Hey @graceful copper!

It looks like you pasted Python code without syntax highlighting.

Please use syntax highlighting to improve the legibility of your code and make it easier for us to help you.

To do this, use the following method:
```py
print('Hello, world!')
```

This will result in the following:

print('Hello, world!')```
You can **edit your original message** to correct your code block.

What part specifically are you having difficulties with?

[graceful copper]

the while loop

and the ending part

[worthy cave]

Which while loop?

[graceful copper]

while ((2p)*x)%1 != 0:
print(f'Remainder = {str((2p)*x - int((2**p)*x))}')
p += 1

    result = '0' + result
result = result[0:-p] + '.' + result[-p:]
print(f'The binary representation of the decimal {str(x)} is {str(result)}') ```

and this too

[worthy cave]

What's your understanding of each? The first is just looping and adding to p while the condition is true.

And the for loop just appears to be a verbose way of writing

result = ('0' * (p - len(result))) + result

[graceful copper]

(p - len(result))

y this

[worthy cave]

I'm assuming that's calculating how much padding to add. p would be the total amount of space to take up. So p - len(result) calculates how much shorter result is than the value p.

And then it adds 0 padding in front to make sure that result's length is p.

[graceful copper]

so they will always be equal ?

[worthy cave]

!e

total = 10
word = 'hello'
n_padding = total - len(word)

padded = ('0' * n_padding) + word
print(padded)

:white_check_mark: Your 3.12 eval job has completed with return code 0.

00000hello

[worthy cave]

Count the letters in the output/.

[graceful copper]

ohk i get it

result = result[0:-p] + '.' + result[-p:]

now what about this?

[worthy cave]

I would print result before and after that line and see what it does.

Inspecting this yourself will be the best way to learn. That's important for debugging anyway.

Do you know what slicing is?

[graceful copper]

also can we convert all decimal to binary?

[graceful copper]

i am doing basis

basic

[worthy cave]

Data is stored in binary, so yes.

Well, let me rephrase that. Not all decimal numbers can be stored in binary.

Some decimal numbers, like the result of 1/3 are infinite, so they can't be stored in a finite amount of space.

[graceful copper]

ohk

Btw

i was doing python from a book

should i do it from yt?

[worthy cave]

I've seen a lot of trash on YouTube. I have more faith in books.

Resources

The Resources page on our website contains a list of hand-selected learning resources that we regularly recommend to both beginners and experts.

[graceful copper]

i think book is a bit tough no?

for me?

[worthy cave]

Tough?

[stuck cradle]

is % 1 intended to check if a float is close to a whole number?

[worthy cave]

Python and programming are as hard as they are. Good material like good books will make it easier to learn. Bad matieral like YouTube videos that only give the illusion of learning seem easy, but don't actually teach.

[graceful copper]

which book will you suggest ?

[worthy cave]

No clue. Read over the Resources link I mentioned. I learned Python more than a decade ago. I can't remember what I used.

[graceful copper]

oh alr

thank you

[worthy cave]

You're welcome.
