python 遍歷字典

起因

for循環遍歷出 對象(字典、列表、字符串···) 的 鍵/值

For循環

• 遍歷鍵

dict = {'Name': 'Runoob', 'Age': 7}
for i in dict：
    print(i)

• 遍歷值

dict = {'Name': 'Runoob', 'Age': 7}
for i in dict.values()
    print(i)

• 遍歷鍵和值

dict.items()
for key,value in dict.items():
	print(key)
	print(value)

• 取列表中的第一個大字典 中 各個小字典的 鍵和值

    latest_list = latest_platform[0].to_dict()      # 取列表第一個值.轉換成字典
    for key1, value1 in latest_list.items():        # items()以列表返回可遍歷的(鍵, 值) 元組數組
        # print(key1) 
        # print(value1)
        if key1 == 'id':
            platform_id = value1
        if key1 == "task_category_id":
            task_category_id = value1
        if key1 == "target_image_category_id":
            target_image_category_id = value1
        if key1 == "platform_key":
            platform_key = value1
