communicate

问题 I'm trying to use my command-line git client and Python's I/O redirection in order to automate some common operations on a lot of git repos. (Yes, this is hack-ish. I might go back and use a Python library to do this later, but for now it seems to be working out ok :) ) I'd like to be able to capture the output of calling git. Hiding the output will look nicer, and capturing it will let me log it in case it's useful. My problem is that I can't get more than the first line of output when I run

问题 The code below works when typed manually however when I run the program.py nothing prints. My ultimate goal is to retrieve this data from user pc to create an easy way to recreate shortcuts.... My users somehow lose them lol import smtplib, os, subprocess, sys from string import ascii_uppercase from cStringIO import StringIO data = os.popen(r"dir %userprofile%\desktop\*.lnk* /s/b").read() file = open("testitem.txt", "w") file.write(data) file.close() my_data = dict(zip(ascii_uppercase,open(

问题 I am using windows 7 64 bit python 2.7 I am opening the file, and monitoring the file changes and then waiting till the opened file is closed. This works well in case of simple notepad file opener. As notepad opens each files in a new process ID whereas notepad++ opens different files in a single notepad++ process ID. ACTIONS = { 1 : "Created", 2 : "Deleted", 3 : "Updated", 4 : "Renamed from something", 5 : "Renamed to something" } FILE_LIST_DIRECTORY = 0x0001 class myThread (threading.Thread

问题 I am trying to read out data from a set of print statements in a C++ program that is being run using a subprocess. C++ code: printf "height= %.15f \\ntilt = %.15f \(%.15f\)\\ncen_volume= %.15f\\nr_volume= %.15f\\n", height, abs(sin(tilt*pi/180)*ring_OR), abs(tilt), c_vol, r_vol; e; //e acts like a print Python code: run = subprocess.call('Name', stdout = subprocess.PIPE, env={'LANG':'C++'}) data, error = run.communicate() However instead of getting the data, all I am getting is a single int,

问题 Recently, I Developed an Experiment Application with VB.net(in Windows platform), When the application collected the data,I want to use R to Analysis the data, But I don't know how to Communicate with R (In other word, I want to send R script to R in my own application ). I will appreciate if anyone could give me some suggetions or some reference documents. Thank you very much! 回答1: I'd suggest you try R.NET. The blurb says: R.NET enables .NET Framework to collaborate with R statistical

问题 Very specific question (I hope): What are the differences between the following three codes? (I expect it to be only that the first does not wait for the child process to be finished, while the second and third ones do. But I need to be sure this is the only difference...) I also welcome other remarks/suggestions (though I'm already well aware of the shell=True dangers and cross-platform limitations) Note that I already read Python subprocess interaction, why does my process work with Popen

问题 I have a script named 1st.py which creates a REPL (read-eval-print-loop): print "Something to print" while True: r = raw_input() if r == 'n': print "exiting" break else: print "continuing" I then launched 1st.py with the following code: p = subprocess.Popen(["python","1st.py"], stdin=PIPE, stdout=PIPE) And then tried this: print p.communicate()[0] It failed, providing this traceback: Traceback (most recent call last): File "1st.py", line 3, in <module> r = raw_input() EOFError: EOF when

问题 Tried searching for the solution to this problem but due to there being a command Shell=True (don't think that is related to what I'm doing but I could well be wrong) it get's lots of hits that aren't seemingly useful. Ok so the problem I is basically: I'm running a Python script on a cluster. On the cluster the normal thing to do is to launch all codes/etc. via a shell script which is used to request the appropriate resources (maximum run time, nodes, processors per node, etc.) needed to run

问题 Why does communicate kill my process? I want an interactive process but communicate does something so that I cannot take raw_input any more in my process. from sys import stdin from threading import Thread from time import sleep if __name__ == '__main__': print("Still Running\n") x = raw_input() i = 0 while ('n' not in x ) : print("Still Running " + str(i) + " \r\n") x = raw_input() i += 1 print("quit") print(aSubProc.theProcess.communicate('y')) print(aSubProc.theProcess.communicate('y'))
