subprocess

问题 I have been trying to implement a wrapper around subprocess as follows: def ans_cmd_stream_color(inputcmd): """Driver function for local ansible commands. Stream stdout to stdout and log file with color. Runs <inputcmd> via subprocess. Returns return code, stdout, stderr as dict. """ fullcmd = inputcmd create_debug('Enabling colorful ansible output.', LOGGER) create_info('Running command: ' + fullcmd, LOGGER, True) p = subprocess.Popen('export ANSIBLE_FORCE_COLOR=true; ' + fullcmd, stdout

问题 I have a simple python program: test.py: import time for i in range(100000): print i time.sleep(0.5) I want to use another program that executes the above one in order to read the last line output while the above program is counting. import subprocess process = subprocess.Popen("test",stdout=PIPE) sleep(20) # sleeps an arbitrary time print stdout.readlines()[-1] The problem is that process.stdout.readlines() waits until test.py finishes execution. Is there any way to read the last line that

问题 I am trying to run a command through Python's subprocess, but it won't run properly. If I type into the shell: pack < packfile.dat where pack is my software and packfile is the input file, then the software runs fine. If I try this in python: import subprocess as sp import shlex cmd = 'pack < packfile.dat'.split() p = sp.Popen(cmd) The software complains: Pack must be run with: pack < inputfile.inp Reading input file... (Control-C aborts) and it hangs there. This last part is specific to my

问题 How can subprocess be used to open a specific local or network directory in Windows File Explorer , and search for image file names with a specific string. In this case, the requirement is: Only display specific images (out of many), in File Explorer , for a quick visual verification. For this purpose, I am not interested in knowing how to search Windows with os or pathlib . Those methods are clearly explained in Find a file in python 回答1: Note: Search locations must be indexed by Windows
