Скачать или смотреть Running an outside program executable in Python

In Python, you can run external programs (executables) using various methods and libraries. This tutorial will guide you through different ways to execute external programs in Python, including using the subprocess module, os.system(), and os.popen().
The subprocess module is a powerful and flexible way to run external programs. It provides more control and security compared to other methods.
In this example, we use the subprocess.run() function to run the "ls -l" command and capture its standard output. You can replace "ls -l" with any command you want to run.
The os.system() function allows you to run external programs but is less versatile than subprocess. It's suitable for simple commands.
In this example, we use os.system() to run the same "ls -l" command. Note that this method does not provide access to the program's output.
os.popen() is another way to run external programs and capture their output. It provides a file-like object to interact with the program's output.
In this example, we use os.popen() to run the "ls -l" command and read its output. This method is suitable for capturing program output when needed.
Running external programs in Python can be done using the subprocess module, os.system(), or os.popen(), depending on your specific requirements. The subprocess module is the most flexible and recommended method for most use cases due to its control and security features.
Make sure to replace the example command with the specific external program you want to run. Always handle command input securely to prevent security vulnerabilities like command injection.
Remember that running external programs in your Python script may have security implications, so exercise caution when dealing with user-provided inputs and consider using proper validation and sanitization to prevent security risks.
