How to print out the contents of a tuple without commas or parantheses?

The program prints out Peter: Number of completed courses: 2 ('Introduction to programming', 3), ('Math', 5)

But I want it to print out without the parentheses or commas, in my code I tried to do it like *students[name],sep=", ") but it only removed the brackets only.

def add_student(students,name):
    students[name] = set()

def print_student(students, name):
    
    if name not in students:
        print(f"{name} does not exist in the database")
    else:
        print(f"{name}:")
        print(f"Number of completed courses: {len(students[name])}")
        print(*students[name],sep=', ')
        total_score = 0
        for course in students[name]:   
            total_score += course[1]
        try:
            print(f"average grade : {total_score/len(students[name])}")
        except ZeroDivisionError:
            print("no completed courses")
                 
    
def add_course(students,name, course:tuple):
    if course[1] == 0:
        return 0
    students[name].add(course)
    
    
students = {}
add_student(students,"Ryan")
add_student(students,"Chris")
add_student(students,"Peter")
add_course(students,"Ryan",("Linear Algebra",9))
add_course(students,"Peter",("Math",5))
add_course(students,"Peter",("Program",0))
add_course(students,"Peter", ("Introduction to programming",3))
print_student(students,"Peter")
print_student(students,"Ryan")

This should be what you are looking for

for course in students[name]:
    print(f"{course[0]} ({course[1]})")

output:

Introduction to programming (3)
Math (5)

A tuple is always ordered and unchangeable.

When you add courses down below in your code you are giving an argument as a tuple

add_course(students,"Peter",("Program",0))
#                           (tupItem0, tupItem1)  <-- The basic form of a tuple

By simply printing a tuple you get the entire structure

"('Program',0)"

You get data out of a tuple like you do a list

foo = ('Program',0)
bar = foo[0] # Bar is now "Program"

In your program when you do this:

print(*students[name],sep=', ')

You are printing the entire list of tuples. For explanation purposed I'm going to do it like the following.

outString = ""

for item in students[name]:
  outString += item[0] + ", "

print(outString[:-2])

Which should get you all of the courses out of your data structure

To print the content of a tuple with a simple separator, use join() as in:

print(" ".join(my_tuple))

will show the contents with spaces between. If you want them 'butt up' to each other...

print("".join(my_tuple))

With a 'nice' comma-space separator...

print(", ".join(my_tuple))
