Python print out of scope?

Question

import Course
import Person
import Student


CREATE = 1
ADD_STUDENTS = 2
COURSE_INFO = 3
ADD_SCORES = 4
QUIT = 5


def main():

  choice = 0

  while choice != QUIT:
    choice = get_menu_choice()

    if choice == CREATE:
        add_Course()
    elif choice == ADD_STUDENTS:
        add_Student()
    elif choice == COURSE_INFO:
        view_Course()
    elif choice == ADD_SCORES:
        add_Scores()
    elif choice == QUIT:
        quit()



def get_menu_choice():
  print()
  print(" Welcome to CourseAware's Faculty Menu")
  print('---------------------------')
  print('1. Create Course ')
  print('2. Add Students to a Course')
  print('3. View Course Information')
  print('4. Add Test scores to a Course')
  print('5. Exit')
  print()

choice = int(input('Enter your choice: '))

while choice < CREATE or choice > QUIT:
    choice = int(input('Enter a valid choice: '))

return choice

I'm having a problem in this area. I wanna ask the user to create a course. Once he added the information I want to send it to the option 3 to display it.

def add_Course():

  name = input("Enter course name: ")
  number = input("Enter course number: ")
  units = input("Enter courses units: ")
  instructor = input("Enter courses Instructor: ")
  myCourse = Course.Course(name,number,units,instructor)

  print("Courses' Name: ",myCourse.getName())
  print("Courses' Number: ",myCourse.getNumber())
  print("Courses' Units: ",myCourse.getUnits())
  print("Courses' Instructor: ",myCourse.getInstructor())
  print("Course Added!")
  return myCourse

def add_Student():
  Name = input("Enter First and Last Name of Sudent: ")
  Status = input("Enter Status of Stdent: ")
  GPA = input("Enter Students GPA: ")
  newStudent = Student.Student(Name, Status, GPA )

  print("Student' First Name: ",newStudent.getName())
  print("Student' Status: ",newStudent.getStatus())
  print("Student' Instructor: ",newStudent.getGPA())


  infile = open('student.txt','a')
  infile.write('\n')
  infile.write(newStudent)

So once the user crated the new course, and he chooses to view it I want it to print to the information is entered in the add_Course option. def view_Course():

  print("Courses' Name: ",myCourse.getName())
  print("Courses' Number: ",myCourse.getNumber())
  print("Courses' Units: ",myCourse.getUnits())
  print("Courses' Instructor: ",myCourse.getInstructor())

main()

Thanks any feedback is welcomed !

Firstly, please fix your indentation. Secondly, where are you expecting that to come from in the second version? — Daniel Roseman, Dec 08 '16 at 09:19

I'm still kinda new to programming, but I was thinking since the results i want are printing in the first section. I thought I could just re-print it in the next section. — Supreme, Dec 08 '16 at 09:25

In your second example you do not declare myCourse.

myCourse = Course.Course(name,number,units,instructor)

is missing.

In Python every function has it's own namespace. If you create a variable in the function, it will only live until the function returns and it is only accessible inside the function.

To solve your problem you have to call the first function and have a return value. Then you call the second function with that value:

def add_Course():

    name = input("Enter course name: ")
    number = input("Enter course number: ")
    units = input("Enter courses units: ")
    instructor = input("Enter courses Instructor: ")
    myCourse = Course.Course(name,number,units,instructor)

    print("Courses' Name: ",myCourse.getName())
    print("Courses' Number: ",myCourse.getNumber())
    print("Courses' Units: ",myCourse.getUnits())
    print("Courses' Instructor: ",myCourse.getInstructor())
    print("Course Added!")
    return myCourse

def view_Course(myCourse):

    print("Courses' Name: ",myCourse.getName())
    print("Courses' Number: ",myCourse.getNumber())
    print("Courses' Units: ",myCourse.getUnits())
    print("Courses' Instructor: ",myCourse.getInstructor())

course = add_Course()
view_Course(course)

I see I added the rest of the code. When i do your advise it prompts the user for the course info. I want only to display that when the user chooses that option. — Supreme, Dec 08 '16 at 09:48
Well, that is a different problem and should be a different question. — Klaus D., Dec 08 '16 at 09:49
