在Python中,字典(Dictionary)是一种无序的数据结构,用来存储键值对。字典的键是唯一的,可以是任意不可变的数据类型,例如字符串、数字或元组。而值可以是任意数据类型,包括字符串、数字、列表、字典等。 在某些情况下,我们可能需要更改字典类型的编码方式,以满足特定的需求。这可以通过使用Python内置的一些方法和函数来...
参数 file 必须有一个 write() 方法,该 write() 方法要能接收字节作为其唯一参数。因此,它可以是一个打开的磁盘文件(用于写入二进制内容),也可以是一个 io.BytesIO 实例,也可以是满足这一接口的其他任何自定义对象。 如果 fix_imports 为 True 且 protocol 小于 3,pickle 将尝试将 Python 3 中的新名称映射...
