## Создаём экземпляр { #create-an-instance }

Мы можем создать экземпляр этого класса так:

{* ../../docs_src/dependencies/tutorial011_an_py39.py hl[18] *}

Так мы «параметризуем» нашу зависимость: теперь внутри неё хранится "bar" в атрибуте `checker.fixed_content`.

## Используем экземпляр как зависимость { #use-the-instance-as-a-dependency }

# Run go tool dist to install a command.
# The -v causes dist to print the name of each directory as it runs.
# The -vv causes dist to print each build command as it runs.
# go tool dist clean cleans all directories, not just this one,
# but it's as close as we can get.

# Default target (first).
install:
	go tool dist install -v

verbose:
	go tool dist install -vv

clean:

Durante a instalação do Python, você pode ser questionado sobre a atualização da variável de ambiente `PATH`.

//// tab | Linux, macOS

Vamos supor que você instale o Python e ele fique em um diretório `/opt/custompython/bin`.

Se você concordar em atualizar a variável de ambiente `PATH`, o instalador adicionará `/opt/custompython/bin` para a variável de ambiente `PATH`.
