os – 操作系统通常提供的功能
该 os模块是 CPythonos模块的严格子集。因此，用 CircuitPython 编写的代码可以在 CPython 中运行，但不一定反过来。

-
os.uname() → _Uname
返回操作特定和 CircuitPython 端口特定信息的命名元组。
-
class
os._Uname
基地： NamedTuple
uname() 返回值的类型
-
sysname :str
-
nodename :str
-
release :str
-
version :str
-
machine :str
-
os.chdir(path: str) → None
更改当前目录。
-
os.getcwd() → str
获取当前目录。
-
os.listdir(dir: str) → str
不带参数，列出当前目录。否则列出给定的目录。
-
os.mkdir(path: str) → None
创建一个新目录。
-
os.remove(path: str) → None
删除文件。
-
os.rmdir(path: str) → None
删除目录。
-
os.rename(old_path: str, new_path: str) → str
重命名文件。
-
os.stat(path: str) → Tuple[int, int, int, int, int, int, int, int, int, int]
获取文件或目录的状态。
笔记
在没有长整数的构建上，当代日期的秒数将不适合小整数。所以时间字段返回946684800，即1999-12-31对应的秒数。
-
os.statvfs(path: str) → Tuple[int, int, int, int, int, int, int, int, int, int]
获取文件系统的状态。
按以下顺序返回包含文件系统信息的元组：
相关信息节点参数：f_files, f_ffree, f_avail
和f_flags 参数可能会返回0，因为他们可以在一个端口的具体实施不可用。
-
os.sync() → None
同步所有文件系统。
-
os.urandom(size: int) → str
根据硬件真随机数生成器返回大小随机字节的字符串。当不可用时，它将引发 NotImplementedError。
-
os.sep :str
分隔符用于分隔路径组件，例如文件夹和文件名。
