Here's the debugging process:

1. Reproduce the problem.
2. Describe the bug. Try to get as much input from the user to get the exact reason.
3. Capture the program snapshot when the bug appears. ...
4. Analyse the snapshot based on the state and action. ...
5. Fix the existing bug, but also check that any new bug does not occur.

What are the types of debug?

There are two types of debugging techniques: reactive debugging and preemptive debugging. Most debugging is reactive — a defect is reported in the application or an error occurs, and the developer tries to find the root cause of the error to fix it.

Is debugging easy?

Debugging Is Hard

“Debugging is twice as hard as writing the code in the first place. Therefore, if you write the code as cleverly as possible, you are, by definition, not smart enough to debug it.”

How do you debug a python code?

Starting Python Debugger

To start debugging within the program just insert import pdb, pdb. set_trace() commands. Run your script normally and execution will stop where we have introduced a breakpoint. So basically we are hard coding a breakpoint on a line below where we call set_trace().

What are debugging techniques?

Definition: The important technique to find and remove the number of errors or bugs or defects in a program is called Debugging. It is a multistep process in software development. It involves identifying the bug, finding the source of the bug and correcting the problem to make the program error-free.
