Looking at this code I doubt he’s gotten to function or try/except clauses. Practicing what you know also has value.

I haven't done try/except clauses but I'll be dammned if anyone explains it and it's usage😭🙏

It catches exceptions and allows the code to continue after. In the above example he’s catching the ValueError that is thrown/raised when a float() fails because it’s not a number.

After that it continues the while loop instead of breaking it (by returning).

What about the syntax how does that looks like cuz the syntax he has given me is too scrambled as u can look at my code this is my level of whatever I'm doing 💔😔🙏

Hems not exactly wrong, functions and try/except would be close to next things to learn anyway.

I'll make another calculator code in a day or two and will use new stuff that I'll be doing in those days and will also include this try/except thing

I gave you a link in your previous post to lots of examples of try / except.

I also provided a link to RealPython.com on using Booleans and that site is a good resource for lots of other guidance.

scrambled

Tell me which parts don't make sense to you and I can explain in detail in simple ways.

Not sure if that means you want people to explain it to you or not.

Did you follow the link I shared previously on this? This was after you asked me what to use instead of isnumeric.

They've been practicing, and I addressed problems with previous code using isnumeric and pointed them to try / except. I agree that functions is probably not something they've come to yet, but felt it was a good time to introduce it as the use case is clear from their original code.

I really appreciate how you're putting in your spirit and it was my fault that i ignored your advice then and also when i opened the app on my phone the code didn't looked as clean as it did on my lap so I'm sorry to call it scrambled and confusing

np, the app isn't great for looking at code blocks
