when debugging or trying to understand someone else’s python code, it can be helpful to know what variables and methods are associated with an object. ┬áto get that information, use the dir() method:

(Pdb) dir(pylab.cm.RdBu)

['N', '__call__', '__doc__', '__init__', '__module__', '_gamma', '_i_bad', '_i_over', '_i_under', '_init', '_isinit', '_lut', '_rgba_bad', '_rgba_over', '_rgba_under', '_segmentdata', '_set_extremes', 'from_list', 'is_gray', 'monochrome', 'name', 'set_bad', 'set_gamma', 'set_over', 'set_under']
