Question

I want to my code block execution for every line so that i can simulate and find if any semantic errors in PYTHON.

For this wt do i need to do?

Answer 1

To find semantic errors I use print statements (to look at variables values at the particular place in my code) as professor recommends. It is usually enough - you can put as many of them as practically reasonable for debugging.

Answer 2

@Ashoka try using the Wing101 IDE, it's free and you can download it from here:
http://wingware.com/downloads/wingide-101/

It has a decent debugger, will let you set breakpoints, watch variables, and step through code.

Answer 3

Using print statements definitely works,and I assume that the Wing IDE works, mentioned above, but you can also step through a program with this one below and it's online. It lists variables, etc.
