如何将字典中的字符串值转换为int/float数据类型？

# 示例字典
my_dict = {
    "key1": "10",
    "key2": "3.14",
    "key3": "5"
}

# 转换字符串为int/float
for key, value in my_dict.items():
    if isinstance(value, str):
        if "." in value:
            my_dict[key] = float(value)
        else:
            my_dict[key] = int(value)

print(my_dict)

{
    "key1": 10,
    "key2": 3.14,
    "key3": 5
}
