For example In [1]: e=1./3 In [3]: '% 20.2f' % e Out[3]: ' 0.33' In [4]: '0.33'.rjust(20) Out[4]: ' 0.33' > text42.set_text(str(g)) > > if len(e)>45: > > x = len(e) - 45 > > x = x + 4 > > y = e[x:] > > text41.set_text(str(y)) > > return > I think this is taking the last 41 chars of e if len(e) > 45.
