Export local variables. Useful for debugging.

Debugging inside a function may be tedious because you can’t access the local variables. One of the option is to use the ipython magic:


Or the pdb equivalent:

import pdb

Another option is to insert this export() call in the troubled function, before the exception occurs.



Note: you can also use ‘globals().update(locals())’ directly in your function to debug


  • seems not to work for functions nested in functions

  • 01/05 : doesn’t seem to work at all.. @Erwan

printdbg(*args, **kwargs)[source]

Function that prints only in debug mode. change this at runtime with.

>>> radis.debug = True


Embed this print in a if __debug__ statement:

if __debug__: printdbg(...)

so that printdbg are removed by the Python preprocessor when running in optimize mode:

python -O *.py

See the "DEBUG_MODE" key in radis.config
