I am quite new with development. In some programming language such as python and PHP there is not a good debugger. How is the development going on without a debugger? just put the logs in the source code? Especially for the framework developers, how do they test their codes?
Thank you very much.

Python has a debugger: pdb. If you use Werkzeug, then you can also access each frame of a stack trace and debug there on an error
How a framework development works without a debugger?
