Question

Is there a way that I can run a script from another while getting output as readily as I get by executing it by itself. For example: I use the os.popen3 command to execute abc.py, but I am unable to get output from abc.py as readily as I would with doing python abc.py; it seems that I need to wait for os.popen3 command to finish:

fin, fout, ferr=os.popen3("abc.py")
out = fout.read()
err = ferr.read()
fo.write(out)
fe.write(err)
print out
print err

[EDIT]:此处的胎儿和胎儿分别处理产出和错误记录。

另外,我用什么植被来把产量集中在猪肉中?

Answer 1

次级处理模块是这一选择,但切碎部分是将产出与你的主要圆环相提并论,以实现这一目标,如果你身处,你可以轻易操作另一个透镜,并使用<条码>,即,在座标上使用read,但如果你计划把 application放在窗上,那么,你就应当使用<>斯特罗伯茨(。

关于植被,使用<代码>gtk。文本Buffer associated with a gtk. 文本:<>。



这方面的一个例子是深read。

import gtk
import subprocess
import threading

gtk.gdk.threads_init()

class FollowProcess(threading.Thread):
    def __init__(self, cmd, text_buffer):
        self.tb = text_buffer
        self.child = subprocess.Popen(cmd, shell=True, stdout=subprocess.PIPE)
        super(FollowProcess, self).__init__()

    def run(self):
        while not self.child.poll():
            out = self.child.stdout.read(1)
            if out !=   :
                gtk.gdk.threads_enter()
                self.tb.insert_at_cursor(out)
                gtk.gdk.threads_leave()

def destroy(w, cmd):
    cmd.child.terminate()
    gtk.main_quit()

i = 0
def click_count(btn):
    global i
    message.set_text( Calling button %d  %i)
    i += 1

other_command =  python extranger.py 

w = gtk.Window()
w.resize(400, 400)

message = gtk.Label( Nothing )
tb = gtk.TextBuffer()
tv = gtk.TextView(tb)
scroll = gtk.ScrolledWindow()
scroll.set_policy(gtk.POLICY_AUTOMATIC, gtk.POLICY_AUTOMATIC)
scroll.add(tv)

box = gtk.VBox()
button = gtk.Button( Active button )

cmd = FollowProcess( python extranger.py , tb)

button.connect( clicked , click_count )

w.connect( destroy , destroy, cmd)
box.pack_start(button, False)
box.pack_start(message, False)
box.pack_start(scroll)


w.add(box)
w.show_all()
cmd.start()
gtk.main()


载于extranger.py。

import time
import sys

i = 0
while True:
    print  some output %d  % i
    sys.stdout.flush() # you need this to see the output
    time.sleep(.5)
    i += 1


注意,即便在更新的同时,纽芬兰仍然如何应对。

Answer 2

import subprocess
pro = subprocess.Popen( abc.py )

Is a much better way of fiddling with another scripts ins, outs, and errors.

Answer 3

您提到PyGtk,但您可以尝试PyQt<>,特别是QProces。等级为:

readyReadStandardError
readyReadStandardOutput

Look for a similar tool with PyGtk.
