Below is a working start to a student class that provides a constructor. extend the class so that when a student object is passed to the print function, that it prints the contents of the first attribute, a single space, and the contents of the last attribute. the intended way for you to do this is to override the builtin __str__ method of objects.
student. py 2-
1 - class student:
2 - def , first, last):
3 - self. first = first
4 - self. last = last
5 - def ):
6 - return '{0} {1}'.format(self. first, self. last)

For the closed feedwater heater below, feedwater enters state 3 at a pressure of 2000 psia and temperature of 420 °f at a rate of ix10 ibhr. the feedwat extracted steam enters state 1 at a pressure of 1000 psia and enthalpy of 1500 btu/lbm. the extracted er leaves at an enthalpy of 528.7 btu/lbm steam leaves as a saturated liquid. (16) a) determine the mass flow rate of the extraction steam used to heat the feedwater (10) b) determine the terminal temperature difference of the closed feedwater heater
