Class and calling a method - Zatoichi - Feb-24-2018
class student:
def __init__(self, first_name, last_name, student_id, year):
self.first_name = first_name
self.last_name = last_name
self.student_id = student_id
self.year = year
self.course = []
def __str__(self):
return self.first_name, self.course
def enroll(self, course):
self.course = course
def main():
file = student('John', 'Smith', 'L01234567', 'senior')
print(file)
file.enroll ('CSC225')
main()so when I call enroll on 'CSC225' I want it to print “John is enrolled in CSC225.” But I cannot figure out what I am doing wrong. I just threw in the print statement to test it out but it is not working the way I thought it should. This is the latest error I have been getting when with what I have last tried to get it to work:Error: line 22, in main
print(file)
builtins.TypeError: __str__ returned non-string (type tuple)RE: Class and calling a method - Mekire - Feb-25-2018
You need to construct the string in the
__str__ method if that is what you want it to look like.Also you need to decide if
Student.course is a list or a single item.class Student(object):
def __init__(self, first_name, last_name, student_id, year):
self.first_name = first_name
self.last_name = last_name
self.student_id = student_id
self.year = year
self.course = []
def __str__(self):
return "{} is enrolled in {}.".format(self.first_name, self.course)
def enroll(self, course):
self.course.append(course)
def main():
student = Student('John', 'Smith', 'L01234567', 'senior')
student.enroll('CSC225')
print(student)
main()

Did you get this figured out, or are you still needing help?
