They get logged in StringIO objects which are available as .out and .err. The class also offers summary methods which format this data a bit. A word of caution: because it blocks messages, using this class can make debugging very tricky. If you are having bizarre problems silently, try turning your output traps off for a while. You can call the constructor with the parameter debug=1 for these cases. This turns actual trapping off, but you can keep the rest of your code unchanged (this has already been a life saver). Example: # config: trapper with a line of dots as log separator (final '\n' needed) config = OutputTrap('Config','Out ','Err ','.'*80+'\n') # start trapping output config.trap_all() # now all output is logged ... # do stuff... # output back to normal: config.release_all() # print all that got logged: print config.summary() # print individual raw data: print config.out.getvalue() print config.err.getvalue() sGeneric Output TrapsStandard Output. sStandard Error. s ic Cs—||_||_||_||_tƒ|_tƒ|_t|_ t|_ ||_ ||_ | |_ |o|iƒn|o|iƒndS(N(snamesselfsout_headserr_headssum_sepsStringIOsoutserrsNonesout_saveserr_savesdebugs quiet_outs quiet_errstrap_outstrap_err( sselfsnamesout_headserr_headssum_sepsdebugstrap_outstrap_errs quiet_outs quiet_err((sB/nyx/web/d/b/dbachman/work/src/ipython-0.8.4/IPython/OutputTrap.pys__init__@s           cCsKti|ijo td‚n|i oti|_|it_ndS(sTrap and log stdout.s You are already trapping stdout.N(ssyssstdoutsselfsoutsOutputTrapErrorsdebugs _out_save(sself((sB/nyx/web/d/b/dbachman/work/src/ipython-0.8.4/IPython/OutputTrap.pystrap_outTs    cCsI|i o:ti|ij o td‚n|it_t|_ndS(sRelease stdout.sYou are not trapping stdout.N( sselfsdebugssyssstdoutsoutsOutputTrapErrors _out_savesNonesout_save(sself((sB/nyx/web/d/b/dbachman/work/src/ipython-0.8.4/IPython/OutputTrap.pys release_out\s    cCsN|iiƒ}|o0|io|SqJ|id|id|SndSdS(s'Return as a string the log from stdout.sLog by s: sN(sselfsoutsgetvalues quiet_outsout_headsname(sselfsout((sB/nyx/web/d/b/dbachman/work/src/ipython-0.8.4/IPython/OutputTrap.pys summary_outds cCs|iiƒtƒ|_dS(s7Flush the stdout log.
