python subprocess call python script with arguments

After familiar with Qt qprocess, and then look back to the Python subprocess finally not feel as horrible as before. Like Qprocess, Subprocess's goal is to start a new process and communicate with it.Subprocess. Popen This module mainly provides a class Popen: Class subprocess. Popen (args, bufsize=0, executable=none, stdin=none, stdout=none, stderr

We often encounter the need to implement a complex functional module through C + + or other lower-level languages, and to build a Web-based demo and query data. Thanks to the power and simplicity of the Python language, the Flask framework and the JINJA2 module feature provide a convenient web development capability for Python, which is ideal for building demos. At the same time,

(stop) child process. Under the Windows platform, this method will call Windows API TerminateProcess () to end the child process.Popen.kill ()Kills a child process.Popen.stdinIf the Popen object is created, the parameter stdin is set to Pipe,popen.stdin will return a file object for the policy child process send instruction. Otherwise, none is returned.Popen.stdoutIf the Popen object is created, the parameter stdout is set to Pipe,popen.stdout will r

Python 3 uses subprocess to implement pipeline (pipe) Interactive Operation read/write communication, pythonsubprocess Here we use shell in Windows for example: From subprocess import * # because it is an example, all data is imported. To facilitate your understanding, we use a simple piece of code to describe: We can see that we use popenizer to create a sub-pr

Python subprocess. Popen communicate () and wait () usage difference, pythonpopenwait The reason for this problem is that the program has not returned since the wait method of Popen is called. Google found that wait may cause deadlocks.

In the C language, a process can fork out a subprocess and let the child process exec a new command. In Python, we fork a child process through the subprocess package of the standard library and run a new program in the child process. There are several functions in the subprocess package that create child processes, e
