Symbolic debugging is useful for checking out the interface to hardware - single stepping through each line of code, and looking at the registers/variables. Symbolic debugging often relies on a toolchain that can be difficult to get right - so often its more pain to setup and debug the debugger than it is to use other methods.
Retrofitting symbolic debugging to a large project often doesn't work - so it may not work for the main python code but can be very useful for some integration testing. Your mileage may vary.
ST has developed and made widely available low cost ST-Link. (This is fantastic as its reasonably simply hardware but complex software to access the internals of the processor - other manufacturers let 3rd party's supply commercial debugging hardware)

ST is also supporting an freely downloadable symbolic debugger tool chain at OpenSTM32.org.

If you've used another symbolic debugger with the pyboard please list it here.

###OpenSTM32.org
This is an Eclipse Lunar based toolchain for both Linux and Windows.
I've used it to take a STM32cubeMX example and customize it for the pyboard. As of writing (2015Nov) it doesn't accept the stmhal/build-PYBV10/firmware.ELF.
Download/install the " [System Workbench for STM32](http://www.openstm32.org/System+Workbench+for+STM32)" -
###ST-Link Upload
The ST-Link can also be used to upload to the board - [Building ST-Flash](https://github.com/micropython/micropython/wiki/Building-st-flash)
The ST-Link can be used to upload to the board, see [Building ST-Flash](https://github.com/micropython/micropython/wiki/Building-st-flash).
There is also an STM "STM32 ST-Link Utility" (Windows?)that can be used to verify the ST-Link works and to program to memory
