Use different output styles

Tb.set_style (pt.MSWORD_FRIENDLY) print ('--style:MSWORD_FRIENDLY -') print (tb) tb.set_style (pt.PLAIN_COLUMNS) print ('- style:PLAIN_COLUMNS -') print (tb)

Random style, different each time.

Tb.set_style (pt.RANDOM) print ('--style:MSWORD_FRIENDLY -') print (tb) tb.set_style (pt.DEFAULT) print ('- style:DEFAULT -') print (tb)
