subprocess

问题 I am trying to use Python's Popen to change my working directory and execute a command. pg = subprocess.Popen("cd c:/mydirectory ; ./runExecutable.exe --help", stdout=subprocess.PIPE, stderr=subprocess.STDOUT, shell=True) buff,buffErr = pg.communicate() However, powershell returns "The system cannot find the path specified." The path does exist. If I run pg = subprocess.Popen("cd c:/mydirectory ;", stdout=subprocess.PIPE, stderr=subprocess.STDOUT, shell=True) it returns the same thing.

问题 I need a HTML webpage in my Django app to load and show the continous output of a script in a scrollable box. Is this possible? I'm presently using a subprocess to run a Python script, but the HTML page won't load until after the script has finished (which can take about 5 minutes). I want the users to see something is happening, rather than just a spinning circle. What I have already also unloads the full output of the script with "\n" in the text; I'd like it to output each new line instead

问题 I'm currently looking at Popen to automate the compression & storage of documents. For the compression part, I thought of the following Python line: subprocess.Popen("WinRAR.exe a -r c:\\03. Notes\\AllTexts *.txt", shell=True) I keep having error messages, as the command is not able to deal with a folder name that contains a space ( 03. Notes ). This question was asked before several times, and, I must say that I tried all propositions: raw string, double quotes, triple quotes, ... None of

问题 I not that good in programming and have a problem using the subprocess() command in Python. My program creates the following string: wsl ocrmypdf -sr -l deu "\mnt\z\dms\_inbox\Scan 2019-11-27 13.12.33.pdf" "z:\dms\_inbox\OCR_Scan 2019-11-27 13.12.33.pdf" If I use this command in my Windows 10 DOSbox it is working without issues. Now I want to start it with the following Python command: subprocess.run(cmd, shell=True, check=True, stdout=subprocess.PIPE, universal_newlines=True).decode() While

问题 I was using the subprocess module to run the shell command in python 3. Here is my code import subprocess filename = "somename.py" # in practical i'm using a real file, this is just for example subprocess.call("pep8 %s" % filename, shell=True)) The output for different files is just 0 or 1 . I am quite new to python 3. Using this in 2.7 gives me the desired output, but here i am not able to figure it out. This is the output i get in python 2.7 (for a file named - anu.py ) - anu.py:2:1: W191
