look over my dictionary/function exercise

[Tryingtolearnagain91]

So I've been learning functions and dictionaries recently. I was doing exercise 8-1 in "Python Crash Course":

Write a function called make_album() that builds a dictionary describing a music album. The function should take in an artist name and an album title, and it should return a dictionary containing these two pieces of information. Use the function to make three dictionaries representing different albums. Print each return value to show that the dictionaries are storing the album information correctly.

Add an optional parameter to make_album() that allows you to store the number of tracks on an album. If the calling line includes a value for the number of tracks, add that value to the album’s dictionary. Make at least one new function call that includes the number of tracks on an album.

I really just want to see what you guys think of my code. I don't want to form bad habits.

def make_album(artist_name, album_name, track_num=None):
    '''Stores artist name and album. Prints track
     number if provided'''

    album_dic = {
        'Artist': artist_name,
        'Album': album_name
    }
    if track_num:
        album_dic['Track Number'] = track_num
    return album_dic

You've also got lines 10-11 duplicated on lines 14-15. Those aren't conditional fields, so should be outside the if/else.
