The list of commands with which you can interact with in rpdb can be displayed by typing the help command from the Pdb prompt:

-> def my_func(thread_number):

Among the most useful commands, this is how we insert the breakpoints in the code:

1. Type b and the line number to set a breakpoint. Here, a breakpoint is set in lines 5 and 10:

 (Pdb) b 5
Breakpoint 1 at c:usersgiancarlodesktoppython parallel programming cookbook 2nd editionpython parallel programming new bookchapter_x- code debugging
pdb_code_example.py:5
(Pdb) b 10
Breakpoint 2 at c:usersgiancarlodesktoppython parallel programming cookbook 2nd editionpython parallel programming new bookchapter_x- code debugging
pdb_code_example.py:10

2. It is sufficient to type the b command to display the list of breakpoints implemented:

 (Pdb) b
Num Type Disp Enb Where
1 breakpoint keep yes at c:usersgiancarlodesktoppython parallel programming cookbook 2nd editionpython parallel programming new bookchapter_x- code debugging
pdb_code_example.py:5
2 breakpoint keep yes at c:usersgiancarlodesktoppython parallel programming cookbook 2nd editionpython parallel programming new bookchapter_x- code debugging
pdb_code_example.py:10
(Pdb)

At each new breakpoint added, a numeric identifier is assigned. These identifiers are used to enable, disable, and interactively remove breakpoints. To disable a breakpoint, use the disable command, which tells the debugger not to stop when that line is reached. The breakpoint is not forgotten but is ignored.
