Question

Answer 1

What others said, plus if you read the error message and you couldn't figure out what to do to fix it, you can just Google the error message and look for more information and solutions.

Answer 2

the intrepreter will show the error message and line, you could use this.

Answer 3

I would read the error message from the program. Without any error message it is a little bit more difficult.

If you have a logical error, you should use a debugger. If it is not a complex program, I would try to understand the functioning of the program. You can print some variables output to check that you understood the functioning well.
