Text not showing up
Hi all, I am new to python and trying to write a simple GUI that would
call 2 growisofs processes (dvd burning) at the same time, and retrive
the exit code to be printed on a text box (couldn't find any program
that could use multiple dvd burners, not even k3b). Excuse me if this is
really a simple problem, but two days of googling didn't help.
The program is really simple, I developed the GUI using glade and it
works.
The only thing I would like to improve is that I'd like it to show in
the text boxes messages like "Waiting for use input" or "Burning dvd
please wait", but it looks like even though I don't have any error, the
message won't show up until the burning process is finished (showing
either "burning successfully" or "an error occurred").
I am not sure I made myself clear on this, but I will post the relevant
code trying to explain it:
import os, sys
import gtk.glade
class DVD:
def __init__(self):
print "Initializing the Graphic User Interface: This may take
some time"
self.xml=gtk.glade.XML("./dvd2.xml")
self.window=self.xml.get_widget("dvd")
self.xml.signal_connect('on_quit_clicked', self.Quit)
self.xml.signal_connect('on_burn_clicked', self.Burn)
self.OrdKeys=["comboentry1","entry1","spinbutton1","entry2","esitotext","esitotext1"]
# here esitotext is the box I want the text to show up
def Quit(self, *args):
gtk.mainquit()
def Burn(self, *args):
comand=""
comand2=""
name=self.xml.get_widget("entry1").get_text()#name
for the dvd
path=self.xml.get_widget("comboentry1").get_text() #path to
dvd AUDIO_TS and VIDEO_TS
num=self.xml.get_widget("spinbutton1").get_text() #chosing
the number of dvd to burn
pub=self.xml.get_widget("entry2").get_text()
#publisher
self.xml.get_widget("esitotext").set_text("Waiting for
input") #THIS NEVER SHOWS UP
dvd1="/dev/hda" # this is the first dvd
burner, edit as needed
dvd2="/dev/hdc" # this is the second dvd
burner, edit as needed
comand+="growisofs -dvd-compat -Z "+dvd1+" -dvd-video -V
"+name+" -publisher "+pub+" "+path
comand2+="growisofs -dvd-compat -Z "+dvd2+" -dvd-video -V
"+name+" -publisher "+pub+" "+path
if num == "1":
self.xml.get_widget("esitotext").set_text("Burning the dvd,
please wait")# THIS NEVER SHOWS UP, unless i have an error and
the program
# quits
before executing the command
self.xml.get_widget("esitotext").show()
# don't know if this is correct,
but it doesn't work either
f = os.popen(comand, 'r')
line = f.readline()
error_in_prog = f.close()
if error_in_prog:
error=str(error_in_prog)
self.xml.get_widget("esitotext").set_text("An error
occurred. Burn not completed") # THIS COMES UP as it should
self.xml.get_widget("esitotext").show()
else:
self.xml.get_widget("esitotext").set_text("Burn
completed successfully")# THIS COMES UP as it should
self.xml.get_widget("esitotext").show()
if __name__=='__main__':
main=DVD()
gtk.main()
Any comment, help, url, really appreciated.
Have a nice day
Simone

subprocess.popen how wait complete open process
Hi, I am running a program with the punishment subrocess.Popen(...) what I should do is to stop the script until the launched program is fully open. How can I do this? I used a time.sleep() function but I think there are other ways. Thanks -- https://mail.python.org/mailman/listinfo/python-list
"pip" error message
Hello everyone, I just started using Python to learn a bit of coding, so I'm pretty a newbie to this, I tried to install few extra packages using pip but it doesn't work. When I check for pip version using command line> pip --version I get the following error message: Traceback (most recent call last): File "c:\users\simon\appdata\local\programs\python\python38-32\lib\runpy.py", line 193, in _run_module_as_main return _run_code(code, main_globals, None, File "c:\users\simon\appdata\local\programs\python\python38-32\lib\runpy.py", line 86, in _run_code exec(code, run_globals) File "C:\Users\simon\AppData\Local\Programs\Python\Python38-32\Scripts\pip.exe\__main__.py", line 5, in File "c:\users\simon\appdata\local\programs\python\python38-32\lib\site-packages\pip\_internal\__init__.py", line 40, in from pip._internal.cli.autocompletion import autocomplete File "c:\users\simon\appdata\local\programs\python\python38-32\lib\site-packages\pip\_internal\cli\autocompletion.py", line 8, in from pip._internal.cli.main_parser import create_main_parser File "c:\users\simon\appdata\local\programs\python\python38-32\lib\site-packages\pip\_internal\cli\main_parser.py", line 7, in from pip._internal.cli import cmdoptions File "c:\users\simon\appdata\local\programs\python\python38-32\lib\site-packages\pip\_internal\cli\cmdoptions.py", line 24, in from pip._internal.models.search_scope import SearchScope File "c:\users\simon\appdata\local\programs\python\python38-32\lib\site-packages\pip\_internal\models\search_scope.py", line 11, in from pip._internal.utils.misc import normalize_path, redact_password_from_url File "c:\users\simon\appdata\local\programs\python\python38-32\lib\site-packages\pip\_internal\utils\misc.py", line 31, in *from pip import __version__ * *ImportError: cannot import name '__version__' from 'pip' (c:\users\simon\appdata\local\programs\python\python38-32\lib\site-packages\pip\__init__.py)* I tried to run Repair in Modify Setup and reinstalled python as well but nothing changed.

Re: "pip" error message
Hi all, First of all thanks to all that answered my question. I had already changed the PATH and tried to upgrade pip version but it was not possible to reach pip in any way, the error that I was getting looked like regarding some program file of pip. Anyway after some trying I was able to fix the problem. I found that I had downloaded Python from what I would call "automatic check version link" and that downloaded the 32-bit version, but my notebook have 64-bit, so I changed the version to the 64-bit one. Pip was reachable but I was getting a problem with it again anyway was an easiest fix as I had to take off the -32 from \Python38-32\ in PATH variables, like this: C:\Users\simon\AppData\Local\Programs\Python\Python38\Scripts Bye On 21/04/2020 04:47, Souvik Dutta wrote: Have you tried updating pip?
