A **context manager** in Python is something that you can use in a `with` statement, for example, `open()` can be used as a context manager:

```Python
with open("file.txt") as file:
    file.read()
```

In recent versions of Python, there's also an **async context manager**. You would use it with `async with`:

```Python

    public static final int FILE_OPEN_REQUIRING_OPLOCK = 0x10000;
    /**
     * Any open of this file cannot be exclusive
     */
    public static final int FILE_DISALLOW_EXCLUSIVE = 0x20000;
    /**
     * Reserve an opportunistic lock filter on the open
     */
    public static final int FILE_RESERVE_OPFILTER = 0x100000;
    /**
     * Open a reparse point and bypass normal reparse point processing
     */

     */
