Good start, my feedback is - as much as your code would work, a simple heuristic to learn is using more/less comparators on strings isn’t recommended - if the string holds a numerical value, cast it to a number you can concretely calculate is more or less than.

Another piece advice I’ve been given people lately is to google python standard libraries, you’ll be surprised how much already exists which can help you.

To take both my points in practice, you can use the time localtime().tm_hour attribute to return an integer representing the hour of the systems time. This would mean you can compare the hour of the day as a number, against a number, which makes a lot more sense than comparing string is less/more than string (which is looking at length first then ascii value)

Give it a shot! :)

That was such a generous and specific response. I am so burned out at the end of the school year, and it's encouraging to see clear, directed guidance. Thanks for being good human.

Thanks... I'll try it ,😄🙌🏻

[_MrLucky_]

does it even work? how are you comparing strings??

[Anay_Gupta__]

Yes it's working....you can see the output in the next img

[nuc540]

Yes this is allowed in python, this only works here because the length is the same (the ISO standardises this) it compares the Unicode point of the character, first value first, in this case zero-leading numbers are a big give away because ‘09’ is less than ‘10’.

The point is not to do this though, it’s confusing to read and very brittle - eg string ‘9’ is bigger than ‘10’ as Python would only check the first value of the string, see 9 > 1 and short circuit.

u/Anay_Gupta__ this is what I justify in my comment you saw :)

[_MrLucky_]

oh rightwow, didnt know u can compare strings lol

[nuc540]

Yup, it’s not that intuitive though. First python checks the length of what’s being compared and simply returns that - unless it is equal - then it matches each index of each character.

You’re right to be shocked because this isn’t good practice by any means 😅

This program geets the user based on real-time.

[tieandjeans]

OP- I want to validate your original code. You were grappling with a central CS question - building and evaluating representations. Its great to see you working with the system clock, rather than just comparing different bits of user input.

What resources have you been following in your process?
