subprocess

问题 I'd like to print every line of python script as it's being executed, as well as the log from the console as every line is being executed. For example, for this script: import time print 'hello' time.sleep(3) print 'goodbye' I'd like it to generate the following in the console: line 1: import time line 2: print 'hello' hello line 3: time.sleep(3) line 4: print 'goodbye' goodbye See below for my attempt import subprocess as subp python_string = """ import sys import inspect class SetTrace

问题 I am trying to use APScheduler to run periodic jobs with an IntervalTrigger, I've intentionally set the maximum number of running instances to one because I don't want jobs to overlap. Problem is that after some time the scheduler starts reporting that the maximum number of running instance for a job have been reached even after it previously informed that the job finished successfully, I found this on the logs: 2015-10-28 22:17:42,137 INFO Running job "ping (trigger: interval[0:01:00], next

问题 I understand why using 'shell=True' can be a security risk if you have untrusted input. However, I don't understand how 'shell=False' avoids the same risks. Presumably if I wanted to allow a user to provide an input he might input: var="rm -rf /" My code might simply: subprocess.call(var,shell=True) # bad stuff Or I might do: varParts=var.split() subprocess.call(varParts,shell=False) # also bad, right? It would seem that the assumption is one wouldn't go through the trouble of processing the

问题 I needed help regarding the subprocess module. This question might sound repeated, and I have seen a number of articles related to it in a number of ways. But even so I am unable to solve my problem. It goes as follows: I have a C program 2.c it's contents are as follows: #include<stdio.h> int main() { int a; scanf("%d",&a); while(1) { if(a==0) //Specific case for the first input { printf("%d\n",(a+1)); break; } scanf("%d",&a); printf("%d\n",a); } return 0; } I need to write a python script

问题 I am trying to run git commands through python subprocess. I do this by calling the git.exe in the cmd directory of github. I managed to get most commands working (init, remote, status) but i get an error when calling git add. This is my code so far: import subprocess gitPath = 'C:/path/to/git/cmd.exe' repoPath = 'C:/path/to/my/repo' repoUrl = 'https://www.github.com/login/repo'; #list to set directory and working tree dirList = ['--git-dir='+repoPath+'/.git','--work-tree='+repoPath] #init

问题 can you guys help me to know how to connect a button in my PySimpleGui script which will execute another python script when the run button is pressed/clicked. For now, i've been reading about Subprocess and command = os.popen in a GUI script. layout = [[ sg.Text('Click the button to launch Program')], [sg.Button('Launch')]] win1 = sg.Window('My new window').Layout(layout) win2_activate = False while True: ev1, vals1 = win1.Read() if ev1 is None or ev1 == 'Cancel': break if not win2_activate
