Explanation / Answer

Firstly we have to know what is a debug,

In software development, debugging involves locating and correcting code errors in a computer program. Debugging is part of the software testing process and is an integral part of the entire software development lifecycle.

Some tools, especially open source tools and scripting languages, do not run in an IDE and require a more manual approach to debugging. Such techniques include dropping values to a log, extensive "print" statements added during code execution or hard-coded "wait" commands that simulate a breakpoint by waiting for keyboard input at specific times.
