Answer 1

CODE:

def toJSON():
    # count to keep track of number of objects
    count = 0
    # child object
    d = {}
    # take user input artist
    artist = input("Artist - ")
    # take user input title
    title = input("Title - ")
    # take user input number of tracks
    num = int(input("Number of Tracks - "))
    # insert in dictionary
    d['Artist'] = artist
    d['Title'] = title
    d['Number of Tracks'] = num
    # stores tracks
    t = []
    for i in range(0, num):
        track = input("Track " + str(i+1)+" - ")
        # append track in array
        t.append(track)
    # store it in the dictionary
    d['Tracks'] = t
    # now store the whole object in result dictionary
    # print(d)
# return the result dictionary
    return d


def JSONtoTable(obj):
    # printing its attributes
    print("Artist: ", obj['Artist'],end="  ")
    print("Title: ", obj['Title'])
    # if it has tracks print them too
    for j in range(obj['Number of Tracks']):
        print(obj['Tracks'][j])
    # line change
    print()

# call functions
res=toJSON()
JSONtoTable(res)
