What are the best practices for debugging Python with GDB?

When debugging Python with GDB, it's essential to use the right commands and techniques. Start by ensuring you have the Python debugging symbols installed. Use the run command to start your script, and set breakpoints with break to pause execution at critical points.

How can I inspect variables while debugging?

You can inspect variables using the print command in GDB. For example, print variable_name will show you the current value of that variable. You can also use info locals to see all local variables in the current stack frame.

What should I do if my program crashes?

If your program crashes, GDB will typically show you a backtrace. Use the backtrace command to see the call stack and identify where the crash occurred. This can help you pinpoint the issue.

Are there any specific GDB commands for Python?

Yes, GDB has specific commands for Python, such as py-list to list Python source code and py-bt for a Python backtrace. These commands provide more context for debugging Python applications.
