The installation and environmental settings of the Python 'Sarge' library

Installation and environment settings Python 'Sarge' library In Python, 'Sarge' is a powerful library for interaction with external commands.It provides a simple and intuitive method to call and manage external commands and capture its output. Preparation before installation: To install and use the 'Sarge' library, we first need to ensure that the following conditions are met: 1. Install python: Make sure that Python is installed on your system.You can check whether the Python has been installed correctly by running the `python --Version`.If not installed, you can download the latest version suitable for your system from the official Python website (https://www.python.org). 2. Install PIP: PIP is a Python bag manager. We can use it to install the Python library.You can run `PIP -Version` in the terminal or command line window to check if PIP has been installed.If not installed, you can refer to the instructions on the official website of PIP (https://pip.pypa.io) for installation. Install the 'sarge' library: Once Python and PIP are installed correctly, you can follow the steps below to install the 'Sarge' library: 1. Open the terminal or command line window. 2. Run the following commands to install the 'sarge' library: shell pip install sarge This command will download and install the 'Sarge' library and all its dependencies from the Python software. Environment settings: Once the 'Sarge' is installed, you can start using it in your Python project.The following is a simple example code that demonstrates how to use the 'Sarge' library to call external commands and capture its output: python from sarge import run, Capture # Call the external command and capture the output result = run('ls', stdout=Capture()) # Print command output print(result.stdout.text) In the above code, we use the `Run` function of the` sarge` library to call the `ls` command and capture its standard output through the` Capture` object.Then, we can access the output of the command through the `Result.stdout.text` and print it or further processes it. The above is a brief introduction to the installation and environment setting Python 'Sarge' library.Now, you can start using the 'Sarge' library to interact and process output with the external command!
