In ruby the debugger is invoked by adding the statement
wherever you want to debug your code. This is preceded, of course, by a reference in Gemfile that brings in the byebug gem.
The python equivalent of this is two fold:
- import the pdb (python debugger) gem
- add the line pdb.set_trace() call where you want it
Here’s the color coded example:
import pdb # lines of python code here pdb.set_trace()
That will launch the python debugger right before the line where the pdb.set_trace() call is inserted. Here are some useful commands:
- The s key steps thru the code.
- The n key goes to the next line.
- The q key quits.
