將字典附加到元組列表中

Question

說我得到了以下 dict ：

d = {'x': 1, 'y': 2, 'z': 3}

我想創建一個函數，將每個鍵和它的值附加到一個元組列表中，所以我編碼：

def dict_to_list_of_tuples(dic):
    list_of_tuples = []
    for key in dic:
        list_of_tuples.append((key, dic[key]))
    return list_of_tuples

但我得到以下輸出：

[('x', 1), ('y', 2), ('z', 3)]

雖然我想得到：

[(x, 1), (y, 2), (z, 3)]

Answer 1

您的功能只是list(d.items()) ：

>>> list(d.items())
[('x', 1), ('y', 2), ('z', 3)]

要以您想要的格式打印，只需使用str.format進行您想要的表示：

>>> "[{}]".format(f", ".join(f"({k}, {v})" for k,v in d.items()) )
'[(x, 1), (y, 2), (z, 3)]'

Answer 2

d = {'x': 1, 'y': 2, 'z': 3}

def dict_to_list_of_tuples(dic):
    list_of_tuples = []
    for key in dic:
        list_of_tuples.append((key, dic[key]))
    return list_of_tuples
print(dict_to_list_of_tuples(d))
print("[{}]".format(f", ".join(f"({k}, {v})" for k,v in dict_to_list_of_tuples(d)) ))
