python - 从元组列表创建字典，输出错误

countries = [('AGO', 'ANGOLA'), ('PRT', 'PORTUGAL')]

countries_dict = {}
countries_new_list = []
for country_code, country in countries:
    print country_code
    countries_dict['country_code'] = country_code
    countries_new_list.append(countries_dict)

print countries_new_list

此代码将打印

AGO
PRT
[{'country_code': 'PRT'}, {'country_code': 'PRT'}]

我期望的是：

AGO
PRT
[{'country_code': 'AGO'}, {'country_code': 'PRT'}]

我在这里想念什么？

最佳答案

我建议您在for循环中定义字典countries_dict。

countries = [('AGO', 'ANGOLA'), ('PRT', 'PORTUGAL')]
countries_new_list = []
for country_code, country in countries:
    print country_code
    countries_dict = {}
    countries_dict['country_code'] = country_code
    countries_new_list.append(countries_dict)

print countries_new_list
