```Python
async with lifespan(app):
    await do_stuff()
```

Wenn Sie wie oben einen Kontextmanager oder einen asynchronen Kontextmanager erstellen, führt dieser vor dem Betreten des `with`-Blocks den Code vor dem `yield` aus, und nach dem Verlassen des `with`-Blocks wird er den Code nach dem `yield` ausführen.

In unserem obigen Codebeispiel verwenden wir ihn nicht direkt, sondern übergeben ihn an FastAPI, damit es ihn verwenden kann.

	s := syscall.Statfs_t{}
	err = syscall.Statfs(path, &s)
	if err != nil {
		return Info{}, err
	}
	reservedBlocks := s.Bfree - s.Bavail
	info = Info{
		Total:  uint64(s.Frsize) * (s.Blocks - reservedBlocks),
		Free:   uint64(s.Frsize) * s.Bavail,
		Files:  s.Files,
		Ffree:  s.Ffree,
		FSType: getFSType(s.Type),
	}
	// Check for overflows.

	return false
}

// Close closes the underlying socket file descriptor.
func (restClient *ReconnectRESTClient) Close() error {
	return nil
}

var (
	errLockConflict = errors.New("lock conflict")
	errLockNotFound = errors.New("lock not found")
)

func toLockError(err error) error {
	if err == nil {
		return nil
	}

	switch err.Error() {
	case errLockConflict.Error():
		return errLockConflict

```python

The following block has wrong language code (should be TOML):

```
# This is a sample TOML code block
title = "TOML Example"  # Title of the document
```

### Quotes

- Keep quote style consistent with existing Turkish docs (typically ASCII quotes in text).
- Never modify quotes inside inline code, code blocks, URLs, or file paths.

### Ellipsis

- Keep ellipsis style (`...`) consistent with existing Turkish docs.
- Never modify `...` in code, URLs, or CLI examples.

### Consistency

But let's save you the time of reading the full long specification just to find those little pieces of information you need.

Let's use the tools provided by **FastAPI** to handle security.

## How it looks { #how-it-looks }

Let's first just use the code and see how it works, and then we'll come back to understand what's happening.

## Create `main.py` { #create-main-py }

Copy the example in a file `main.py`:
