選項 3 僅迭代最后一個 key:value 條目而不是整個字典，我可能做錯了什么？
uj5u.com熱心網友回復：
首先，我認為您想將您的選項輸入移到 for 回圈的范圍之外。其次，遍歷字典使用 vin_bag.items()
elif option == 3:
for pair in vin_bag.items():
print(pair)
option = int(input("PLease enter your option: \n"))

elif option == 3:
[print(artist, song) for artist, song in vin_bag]
option = int(input("PLease enter your option: \n"))
