将变量从一个 function 传递到另一个 python 时遇到问题

Question

i wanted to pass in one variable i made in one function into another function in order to print it out and do stuff with it, however i'm having trouble trying to pass the variable i made in the first function into the second function

courses = [{k: json_dict[k] for k in keep_keys}
                    for json_dict in specific_major]
return courses

the courses variable that is above is what i want to use in my next function. i tried returning it and then making a new function and passing it in as a function.

def classes_get(c):
    print(c)

classes_get(courses)

i tried the following code above in jupyter notebook to see if it would print out but i always get this message "courses not defined" even though i run all the code blocks in order and the course variable prints out normally when i call the first function its in. is there a step i'm missing that isn't allowing me to use it in another function?

def get_departments():
    umd_departments = requests.get("https://api.umd.io/v0/courses/departments")
    umd_departments_list = umd_departments.json()

    umd_departments_list2 = json.dumps(umd_departments_list, indent=1)
    department_storage = [department['dept_id'] for department in umd_departments_list]
    print(department_storage)
    dept = input('what department are you  in right now: ')
    dept = dept.upper()
    if dept not in department_storage:
        raise ValueError("department doesn't exist")
    else:
        department_url = requests.get(f"https://api.umd.io/v0/courses?dept_id={dept}")
        specific_major =department_url.json()
        keep_keys = ["course_id", "name", "credits", "sections"]                        
        courses = [{k: json_dict[k] for k in keep_keys}
                    for json_dict in specific_major]

        return courses

edit: get_departments is the first function. sorry for not including all of it

another edit: this is what i tried so far

courses = get_departments()
def get_classes(courses):
    print(courses)
get_classes(courses)

Answer 1

Use the returned value from first function and pass it to the other function. If you are using jupyter notebook, ensure that the get_department function is defined / run before called classes_get .

courses = get_departments()
classes_get(courses)
