Print format

Hi Gigs,

Below is a code that I'm working on:

def class_tuple_create(filename):
    try:
        file = open (filename, 'r')
    except:
        print(filename, 'Cannot be opened')
    else:
        myDict = {}
        for line in file:
            list = line.split()
            course_id = list[0]
            room = list[1]
            name = list[2]
            time = list[3]
            class_data = (room, name, time)
            myDict[course_id] = class_data
        file.close()
        return myDict

def print_classes(myDict):
    print ('ID\tRoom\tInstr\tStart')
    print ('------------------------------')
    for key in sorted(myDict):
        print (key, myDict[key])


class_information = class_tuple_create('xxxxx')
class_information = class_tuple_create('courses.txt')
print_classes(class_information)

I was expecting the output below

Output:
Error: Unable to open xxxxx
ID Room Instr Start
-----------------------------------
CM241 1411 Lee 13:00
CS101 3004 Haynes 8:00
CS102 4501 Smith 9:00
CS103 6755 Rich 10:00
NT110 1244 Burke 11:00

but it's printing the following:

Output:
Error: Unable to open xxxxx !!!
ID      Room    Instr   Start
------------------------------
CM241 ('1411', 'Lee', '13:00')
CS101 ('3004', 'Haynes', '8:00')
CS102 ('4501', 'Smith', '9:00')
CS103 ('6755', 'Rich', '10:00')
NT110 ('1244', 'Burke', '11:00')

Please any advise on how to remove the quotes by printing individual element ?
Below is the ouput of the courses.txt file

Output:
CS101 3004 Haynes 8:00
CS102 4501 Smith 9:00
CS103 6755 Rich 10:00
NT110 1244 Burke 11:00
CM241 1411 Lee 13:00

Input sample please

When you use:

print (key, myDict[key])

Python just takes the standard string representation of the values (and since you value are tuples, you get a tuple display). If you want more control, you have ti unpack the tuples, and then print each part individually:

room,name,time= myDict[key]
print (key,room,name,time)

In practice, you should use a string format() for such output.

Otherwise:

• myDict is a truly awful name for a variable. Why not courses?
  
• In the same vein, the key in for key in sorted(myDict) would be better named course_id
