in java we can tell what's the exact error by using
catch(Exception e){
e.printStackTrace();
//or
System.out.println(e.getMessage());
// or just printing the exception class
}
is that possible in python in any way ?

Hi, I need assistance aka HELP!
I've done this calculation in various ways some of printed nothing but zeros non stop.
Using while loop calculate all numbers 1 to 1000 add numbers to sum = sum + i
int sum = 0;
// use a while loop to calculate the sum of 1 to 1000
While(int sum = 0; sum >= 1000; sum = sum + I){
System.out.println(sum);
}
