make_dictionary Creates a dictionary from a file's contents. Each line in the file is split into a list at commas. If, after splitting, the list contains exactly 2 parts, the first item is added to the dictionary as a key and the second item is the value. If the provided file doesn't exist, the message "File doesn't exist" is printed to the terminal and an empty dictionary is returned.

Question

The following Python code is a partially written function that attempts to read a file's contents into a dictionary. Fill in the missing code in the make_dictionary function. You do not need to copy any of the existing code. Just write the code that would go in place of "YOUR CODE HERE".

def make_dictionary(filename):
'''
Function -- make_dictionary
Creates a dictionary from a file's contents.
Each line in the file is split into a list at commas.
If, after splitting, the list contains exactly 2 parts,
the first item is added to the dictionary as a key
and the second item is the value. If the provided
file doesn't exist, the message "File doesn't
exist" is printed to the terminal and an
empty dictionary is returned.
Parameter:
filename -- The name of the file to open.
Returns:
A dictionary of the file's contents, if the
file matches the expected format. Otherwise, an
empty dictionary is returned.
'''
contents = {}

# YOUR CODE HERE

return contents

Example

If the contents of the file passed to the function looked like this:

CS 5004, Object-Oriented Design, Evening Section
CS 7580, Special Topics in Software Engineering
CS 8674, Masters Project

... the returned dictionary would look like this:

{
"CS 7580": "Special Topics in Software Engineering",
"CS 8674": "Masters Project"
}
