WHat does x_train, y_train = zip(*train) mean? WHat does the "zip" and the asterick mean? How are they dividing X and Y ?

for x in range(40):
    
    y, sr = librosa.load('C:/audio files/folderCat/'  + str(x)+'.wav',   
    duration=2.95)  
    ps = librosa.feature.melspectrogram(y=y, sr=sr)
    
    if ps.shape != (128, 128): continue
    #print(ps.shape)
    D.append( (ps, 1) )

#print(D)

for x in range(40):
    
    y, sr = librosa.load('C:/audio files/folderDog/' +  str(x)+'.wav',  
    duration=2.95)  
    ps = librosa.feature.melspectrogram(y=y, sr=sr)
    if ps.shape != (128, 128): continue
    D.append( (ps, 2) )

print("Number of samples: ", len(D))

#print(D)
dataset = D
random.shuffle(dataset)

train = dataset[:20]
test = dataset[20:40]
x_train, y_train = zip(*train)
x_test, y_test = zip(*test)
