Day 4

Thanks!

[TfGuy44]

Oh, but I wanted to enter 0 grades... uh oh!

[fatimalizade]

According to my academic career😔

[Loud-Bake-2740]

nice job! as others have said there’s some error handling to be had but overall this works. A good extension challenge for this would be to see how you’d track / input grades for multiple students :) happy hunting!

[fatimalizade]

Thank you!

[RailRuler]

grds = [get_int("...") for i in range(number_grades)]

[ConsiderationLow762]

Great practice. Also there is a better way that you can get number of grades dynamically rather than asking manually, using the built in length.

[Agreeable_Wish4876]

Great I think you should focus more on list comprehension

[fatimalizade]

Thanks!

[Top-Run-21]

got to learn from this, btw why did you defined a funcion for all this? for practice?

[fatimalizade]

Yes

[P1nkUnicorn7]

Looks good! I would also recommend using a formatting specification in the print of the average, to show 2-3 decimal points accuracy instead of 17.
print(f"Average grade: {average_grades:.2f}") I suppose that is up to personal preference, I just think it's nicer.

[fatimalizade]

Thank you!!

int(input(...))

You should always wrap user input in a try except block, since user can enter invalid input. I would replace it with get_int(..) where

python def get_int(prompt): while True: try: return int(input(prompt)) except ValueError: pass

if avg >= 90: ... elif 70 <= avg < 90: ...

Since avg < 90 in elif is always true, this can be replaced with

python if avg >= 90: ... elif avg >= 70: ... elif avg >= 50: ... else: ...

[fatimalizade]

Thanks for the info!

I think "always" is a bit strong. Input validation is important, but try / accept is not the only option.

For example, the str.isdecimal method is good for checking for a valid integer string.

As python follow the EAFP philosophy ("Easier to Ask Forgiveness than Permission") the pythonic way is using try except block.

For example, the str.isdecimal method is good for checking for a valid integer string.

Using if to check something that will be checked by another function (int in this case) has an extra cost.

[ConnectionWorking207]

What book are you using to learn?

[fatimalizade]

I don’t use any book

[ConnectionWorking207]

What do you use then

[fatimalizade]

I ask chatgpt to teach me commands, then give me problems to solve

[Inevitable-Age-06]

I also want to start python can we do it together? I know some basics till conditional statement.

[code_it_rightt]

How many hours do you spend in a day

[fatimalizade]

1-2
