#觀念：字典dict的3種迴圈
#（1）迴圈印出全部的欄位：for k in phone.keys()
#（2）迴圈印出全部的值：for v in phone.values()
#（3）迴圈印出全部的鍵+值：for v in phone.values()

#-----------------------
#1.建立一個手機的資料
#phone = {"品牌":"samsung","規格":"galaxy s22","銷售年":2022}
#-----------------------
print()

#2.迴圈印出全部的欄位：for k in phone.keys()
#-----------------------

print()
#-----------------------
#3.迴圈印出全部的值：for v in phone.values()
#-----------------------


print()
#-----------------------
#4.迴圈印出全部的鍵+值：k,v in phone.items():
