GDB Python

GDB Python:

To use GDB (GNU Debugger) with Python, you can follow these steps:

1. Install GDB: If you don’t have GDB installed on your system, you can install it using the package manager specific to your operating system. For example, on Ubuntu, you can use the following command:

   arduinoCopy code

   sudo apt-get install gdb

2. Launch GDB: Open a terminal window and start GDB by typing the following command:

   Copy code

   gdb python

3. Set breakpoints: Once GDB is running, you can set breakpoints at specific locations in your Python code. For example, to set a breakpoint at line 10 of your Python script, use the following command in the GDB prompt:

   kotlinCopy code

   break filename.py:10

4. Run your script: To execute your Python script within GDB, use the run command:

   arduinoCopy code

   run

5. Debugging: When your script hits a breakpoint, GDB will pause the execution and give you control. You can use various GDB commands to inspect variables, step through the code, and analyze the program state. Some commonly used commands include:

   • next: Execute the next line of code.
   • step: Step into the next function call.
   • print variable_name: Print the value of a specific variable.
   • continue: Continue the execution until the next breakpoint or the end of the program.
   • backtrace: Show the current call stack.

6. Exiting GDB: To exit GDB, you can use the quit command or press Ctrl + D.

Please note that GDB is primarily a C/C++ debugger and may not provide all the features and capabilities specific to Python debugging. Alternatively, you can use Python-specific debuggers like pdb (Python Debugger) or IDEs with built-in debugging support, such as PyCharm or Visual Studio Code, which offer more advanced debugging features for Python.
