How to use the output of the "Sarge 'library to capture the sub -process (Capturing Subprocess Output with' Library in Python) in Python

In Python, you can use the "SARGE" library to capture the output of the sub -process."SARGE" is a library for processing sub -processes. It provides a convenient method to execute and manage sub -processes and capture its output. To use the "SARGE" library to capture the output of the sub -process, the library must be installed first.You can use the PIP command to install: pip install sarge After installing the library, you can use it in the Python code.Below is an example code that uses the "SARGE" library to capture the sub -process output: python from sarge import capture_stdout # A process command result = capture_stdout("echo Hello World") # print(result.stdout.text) In this example, we use the "SARGE" library's `Capture_Stdout` function to execute a sub -process command.This function executes a specified command and captures its standard output.Here, the command we execute is "Echo Hello World", which will output "Hello World". `Capture_Stdout` function returns a` Command` object, which contains the captured sub -process output.We can obtain the standard output of the child process by accessing the `Stdout` property.In this example, we use the `Result.stdout.text` to obtain the text content of the standard output and print it out. In addition to the `Capture_Stdout` function, the" Sarge "library also provides other similar functions, such as the standard error output used to capture the sub -processes, and` Capture_both `is used to capture standard output and standard error output at the same time. In more complicated cases, you can manually execute and manage sub -processes by using the `Popen` class in the" SARGE "library.The `Popen` class provides more flexibility and control, which can customize the behavior and input and output processing of sub -processes. In short, using the "Sarge" library can easily execute the sub -process command in Python and capture its output.By using this library, you can better control and handle the child processes to achieve more powerful functions.
