Python子进程python脚本

Question

I want to create python console that can run not only regular commands but also python and other commands. For example how can I run this script and provide input with subprocess?

print("Welcome to simple program !")
data = input("Enter something: ")
print(data)

Answer 1

Try this:

import subprocess

print("Welcome to simple program !")
cmd= input("Enter something: ")
subprocess.run(cmd, shell=True)

Security Considerations Unlike some other popen functions, this implementation will never implicitly call a > system shell. This means that all characters, including shell metacharacters, can safely be passed to child processes. If the shell is invoked explicitly, via shell=True, it is the application's responsibility to ensure that all whitespace and metacharacters are quoted appropriately to avoid shell injection vulnerabilities. When using shell=True, the shlex.quote() function can be used to properly escape whitespace and shell metacharacters in strings that are going to be used to construct shell commands. reference
