Here endeth the first string > "\n The fractional sigma (FractionalSTD)" > " of UCC that was input was %7.5f " % (self.fractsigma_ucc)) And here the second. Returning two strings separated by a comma makes it a tuple. Instead put the two values in a tuple at the end of a single concatenated string. And while at it make life easier for your self and use triple quotes: def __str__(self): return """ Output from __str__ of POCWP. After the first turnover, during the 'Population Of Capitals Init' cycle, the productivities were raised from 1.0 to a specific Unit Constant Capital (UCC) for each specific capital: The input value for the mean of UCC was %7.5f The fractional sigma (FractionalSTD) of UCC that was input was %7.5f """ % ( self.ucc, self.fractsigma_ucc) Tweak the formatting to suit. However, I'm not sure thats really a good use of __str__, I might be tempted to make that an explicit method that's called pprint() - for pretty-print - or somesuch. __str__() methods are usually a fairly cocise depiction of the objects state that you can embed in a bigger string. Maybe pprint() would look like def pprint(self): return """ Output from __str__ of POCWP. After the first turnover, during the 'Population Of Capitals Init' cycle, the productivities were raised from 1.0 to a specific Unit Constant Capital (UCC) for each specific capital: %s""" % self And __str__() def __str__(self): return """ The input value for the mean of UCC was %7.5f The fractional sigma (FractionalSTD) of UCC that was input was %7.5f """ % (self.ucc, self.fractsigma_ucc) Thus pprint() uses str() to create the long version while str() just gives the bare bones result.
