Hello I'm begganer
Isn't in this code the result should be (4)
Because it's (0.4) so why it's 1200
And how to solve this

1200 divided by 3000 is 0.4 you are right, but
As 1200 is less than 3000, it cannot divide even once, so the remainder is 1200

[maiden veldt]

a%b==c when a = b*(a//b)+c

1200//3000 is 0
So the remainder is 1200-0*3000 = 1200

I don't know why you think it should be 4 "because it's 0.4"
1200/3000 (normal division) is 0.4... But that doesn't have any *10 there?

Or were you thinking that a%b means "how many percent of b is a?" - but then you'd expect 40, not 4...

[neat glade]

in other words, what did you think the % operator does @little anchor ?

[little anchor]

It's the reminder?

[uneven root]

*remainder

But it's better known as the "modulus operator"

[neat glade]

yes, and if you divide 1200 by 3000, how many times does 3000 fit in 1200, and how much is left over after the division?

[little anchor]

I tried to do like how many hours and minutes in 5000 second but look at last line it says wrong

[neat glade]

can you please at least answer my question?

also, please learn how to use the screen capture tool rather than taking photos of your screen

[little anchor]

Yes I anderstund there is no reminder but what should I do instead

[little anchor]

What is this I'm new

what you probably want is divmod()

https://docs.python.org/3.14/library/functions.html#divmod

!e

hours, seconds = divmod(5000, 3600)
minutes, seconds = divmod(seconds, 60)
print(f"{hours} h, {minutes} m, {seconds} s")
print(hours * 3600 + minutes * 60 + seconds)

[remote needle]

:white_check_mark: Your 3.14 eval job has completed with return code 0.

001 | 1 h, 23 m, 20 s
002 | 5000

[little anchor]

Sorry I don't know much in laptop can you help with this picture

[little anchor]

🫨🫨

[neat glade]

!e

# an alternative way
minutes, seconds = divmod(5000, 60)
hours, minutes = divmod(minutes, 60)
print(f"{hours} h, {minutes} m, {seconds} s")
print(hours * 3600 + minutes * 60 + seconds)

[remote needle]

:white_check_mark: Your 3.14 eval job has completed with return code 0.

001 | 1 h, 23 m, 20 s
002 | 5000

[neat glade]

does this way make more sense to you?

[little anchor]

Do you know that I'm begganer?what is devmod ? Or should I wait and I will understand later in advance

[neat glade]

I gave you a direct link to its documentation – did you read it?

it makes a division and returns you the quotient and the remainder in one shot

quite convenient for operations like this

[little anchor]

Yes didn't understand the translate is bad

[little anchor]

Ok maybe over time in learning I will use this

Thank you

[neat glade]

it's not a complicated function

!e

print(divmod(10, 3))

!e

print(divmod(10, 3))

[remote needle]

:white_check_mark: Your 3.14 eval job has completed with return code 0.

(3, 1)

[neat glade]

so 10 // 3 == 3 and 10 - 10 // 3 == 1, easy enough?

let me know if there's something you don't understand

[cedar frost]

!e print((10 - 10 // 3) == 1)

[remote needle]

:white_check_mark: Your 3.14 eval job has completed with return code 0.

False

[neat glade]

woops

I suppose 10 - 10 // 3 * 3 == 1 would have been better, but that does get a bit complex looking

it was intended to show that the remainder from the integer division would be 1

[little anchor]

I understand this

[neat glade]

alright – if there's nothing else, you can do !close

[cedar frost]

divmod() is just a shortcut for // and % combined, eg:

minutes = seconds // 60
seconds = seconds % 60

# is equal to

minutes, seconds = divmod(seconds, 60)

[little anchor]

I don't know divmod yet i will wait until I learn it thank you

[cedar frost]

BTW, in your example:

hours = seconds // 3600
rest_hours = seconds % 3600

the rest_hours are still seconds and not minutes like you have printed.

[little anchor]

Yes I was going to ask that

Buy why

[cedar frost]

Because you used the seconds, a modulo operation will not convert them to minutes.

1 hour == 3600 seconds, 5000 - 3600 == 1400 but still seconds

[little anchor]

Sorry but how did that printed at result

I typed (+str (rest_hour ) which is the reminder of (5000/3600) that is should be (38)

Because 5000/3600 is 1.38

[cedar frost]

!e

print(5000 / 3600)
print((5000 / 3600 - 1) * 3600)

[remote needle]

:white_check_mark: Your 3.14 eval job has completed with return code 0.

001 | 1.3888888888888888
002 | 1399.9999999999998

[cedar frost]

So, no -> 5000 % 3600 is 1400

The remainder of a division is not the fraction part of the result. It is the whole number which does not get used by the division.

[little anchor]

Oh thank you I didn't know now I understand

Now it's done thank you🥳🥳

[cedar frost]

It would be more accurate to name them rest_secondes (and rest_minutes).

@little anchor

go to windows search

bottom left of your screen Type here to search

and then type snipping tool

then click the program that shows up
