### Profile functions from command line

Source: https://github.com/mgaitan/pytest-line-profiler/blob/main/README.md

This command shows how to invoke pytest with the line-profiler plugin enabled. It specifies the functions to be profiled directly on the command line using the `--line-profile` option, followed by the path to the functions.

```bash
pytest --line-profile path.to.function_to_be_profiled [...]
```

### Profile functions using pytest mark

Source: https://github.com/mgaitan/pytest-line-profiler/blob/main/README.md

This Python code demonstrates how to use the pytest-line-profiler plugin by marking a test function with `@pytest.mark.line_profile.with_args()`. The arguments to `with_args` are the functions that should be profiled. When the test runs, line-profiler will generate reports for these specified functions.

```python
import pytest

def f(i):
    return i * 10

def g(n=10):
    return sum(f(i) for i in range(10))


@pytest.mark.line_profile.with_args(f, g)
def test_as_mark():
    assert g() == 450
```
