Python Python Basics (Retired) Things That Count Exceptions

When will the except clause get executed ? Because if we give a float , it will get converted to int in the try clause

When I give a float in the first place , wouldn't it always get converted to an int so that the except clause never gets executed ?? Need a little help here .

Thanks in advance

Hi there,

It won't be converted to an int - if there's a decimal place, the conversion to an int will fail; "blows up", I think the teachers called it, meaning that execution will move to the except:

Hi Steve,

Thanks for the reply.. But if we pass a decimal to an int function , say int(2.3) , wouldn't it return 2?? In that case try statement will always get executed , whether we provide an integer or a decimal number as an input .. Please help .. Thanks in advance

I think you're passing a string into a method which will try to convert it to an int. I think that's a step too far. Yes, you can change floats to ints by casting them, but this is startng with a string - I think the first try will fail (try it!) so the except: will be used.

i got the same question. the try catch block was very confusing. Kenneth missed explaining two important things when explaining this video.

  1. The number input is a string and
  2. In the shell he didn't walk through how the compiler would interpret the code when it is executed.

I am little disappointed in this video as kenneth left those two points
