Subprocess Module允许你生成一个或多个进程，并且可以跟它交互，并且获取返回的结果，这个模块想要替换掉几个老的方法： os.system os.spawn* 所以以后跟系统交互的命令，尽量用subprocess建议调用subprocess的run()方法去跟系统进行调用，更高级的方法，使用popen() ;run()方法其实就是封装的popen。run()方法在python3.5才有，python2.x没有，2.x用subprocess.call()，当然python3.X版本也支持call()Common methods of

code is as follows:#include using namespace Std;int main (int argc, const char *artv[]){int x, y;cout CIN >> X;cout Cin >> y;cout return 0;}The Supprocess module provides functions that allow us to create processes.Subprocess.call (*popenargs, **kwargs)Executes the command. The function waits until the child process finishes executing and returns the ReturnCode of the process. The example at the beginning of the article demonstrates the call function

After being familiar with the qprocess of Qt, looking back at the Python subprocess finally did not feel as scary 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, s

This article has shared the use of Python to execute shell scripts and dynamic communication and subprocess basic use, interested in small partners can take a look at Recent job requirements have encountered this situation in the Web side to get the contents of the configuration file and into the shell script to dynamically pass in parameters There are several w

Python provides multiple modules for creating sub-processes. I prefer to use the subprocess module because the python manual contains the following: This module intends to replace several other, older modules and functions, such as: OS. System, OS. Spawn *, OS. popen *, popen2. *, commands .* Subprocess is used to repl

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,

This example describes the use of the subprocess module in Python. Share to everyone for your reference. Specific as follows: Execute command: >>> subprocess.call (["LS", "-l"]) 0>>> Subprocess.call ("Exit 1", shell=true) 1 The cmd command in the test call system shows the result of the command execution: X=subprocess.check_output (["Echo", "Hello world!"],shel

subprocess ModuleThe subprocess module targets to start a new process and communicate with it.1. Call: Executes the program, waits for it to complete, returns the status code. ImportsubprocessRet1 = Subprocess.call (["CP","-P"],Shell=True)Ret2 = Subprocess.call (["CP","-P"],Shell=False)Shell = True allows the shell to be a string form.def

Sometimes you need to use JAVA to directly call the python script to execute some server monitoring tasks. This article provides an example code for java to directly call a python script: Import java. io. BufferedReader;Import

Recently there is a monitoring requirement, you need to execute the script on each node of the cluster remotely, and get the result of the script execution, in order to be safe, do not need the account password to log in the host, require only the method that calls the remote script module can be implemented.Summarize the Pyt
