Python Python Basics (Retired) Things That Count Exceptions

The difference between Try/Except and If/Else

Does If/Else serve a similar function to Try/Except ? For example, in the video, we use Try/Except to determine if the input number can be turned into int if not turn it into a float. Can we use if and else like if the number can't be turned into an integer then else turn it into a float?

If/Else, expects two possible scenarios which both work, Try/Except expects one scenario but if it doesn't happen it doesn't crash, instead it does something else. It is like an If/Else for errors which would crash an If/Else.

Goodluck! --Ricky

Thank you Ricky !

So its safe to say: use try/except if the code in the try block might crash the program (based on user input). And if/else for other regular logic and program flow?
