在字典列表中将单引号更改为双引号

def replace_quotes(dictionary_list):
    for i in range(len(dictionary_list)):
        for key, value in dictionary_list[i].items():
            if isinstance(value, str):
                dictionary_list[i][key] = value.replace("'", "\"")
    return dictionary_list

# 示例字典列表
example_list = [
    {"name": "John", "age": '25', "city": 'New York'},
    {"name": 'Alice', "age": "30", "city": "San Francisco"}
]

# 调用替换方法
modified_list = replace_quotes(example_list)

# 打印结果
for item in modified_list:
    print(item)

{'name': 'John', 'age': "25", 'city': "New York"}
{'name': "Alice", 'age': "30", 'city': "San Francisco"}
