What is bug life cycle with example?
A Defect life cycle, also known as a Bug life cycle, is a cycle of a defect from which it goes through covering the different states in its entire life. This starts as soon as any new defect is found by a tester and comes to an end when a tester closes that defect assuring that it won't get reproduced again.

- Isolate. Isolate is a step to separate the buggy code with other healthy code; I usually make an Unit Test referencing that part of code and then reproduce the bug using that unit test; ...
- Fix. ...
- Review. ...

What is Python debugging?
Python has a built-in debugger called pdb . It's a simple utility with a command line interface that does the main job. It has all the debugger features you'll need, but if you're looking to pimp it up a little, you can extend it using ipdb, which will provide the debugger with features from IPython.
What is difference between testing and debugging?
Main objective of Testing is to find bugs and errors in an application which get missed during the unit testing by the developer. On other hand the main objective of Debugging is to find the exact root cause at code level to fix the errors and bugs found during the testing.
