I used python3.7 in windows7.
When I tried to run this line: suinfo.dwFlags |= subprocess._subprocess.STARTF_USESHOWWINDOW
error occurs: module 'subprocess' has no attribute '_subprocess'
import os
import sqlite3
import subprocess
import time
import re
from django.core.mail import send_mail
from django.http import HttpResponse
suinfo = subprocess.STARTUPINFO()
suinfo.dwFlags |= subprocess._subprocess.STARTF_USESHOWWINDOW
How to deal with that?
There is no such thing as subprocess._subprocess, the constant is straight under subprocess:
suinfo.dwFlags |= subprocess.STARTF_USESHOWWINDOW
See the docs: https://docs.python.org/3/library/subprocess.html#subprocess.STARTF_USESHOWWINDOW

I've been working on an app to manage a little store with Python and SQLite. For GUI I used tkinter. I've written 13 Python scripts to make the app work. One of them call "principal.py" which imports most of the scripts and the other scripts import other modules like tkcalendar or xlwt (to write excel sheets), etc...
This is an example from "principal.py" first lines of code

This is how my files are structured and how it works when I run the script from vscode
But when I tried to make an exe from my little project using PyInstaller, it looks incomplete like this:
this is how it looks like when I run the exe file from the "dist" folder
I worked like this
Create the spec file with pyi-makespec principal.py
Re-write the principal.spec to save the database path
pyinstaller --windowed principal.spec
SUMMARY:
Unable to run a time-lapse Python3 script due to a module not being installed. I am running Raspian Lite on Raspberry Pi Zero W.
THINGS I'VE TRIED:
I've tried installing picamera module for python. Tried googling the error and came across https://raspberrypi.stackexchange.com/questions/88339/importerror-no-module-named-picamera
Here is a list of installed modules. I can't see picamera on there??

CODE BELOW:
from time import sleep
import picamera
with picamera.PiCamera() as camera:
camera.resolution = (1024, 768)
WAIT_TIME = 300
with picamera.PiCamera() as camera:
camera.resolution = (1024, 768)
for filename in
camera.capture_continuous('/home/pi/camera/img{timestamp:%H-%M-%S-%f}.jpg'):
sleep(WAIT_TIME)
The expected result is images to appear in the camera folder timestamped every 5 minutes.
While it is not stated in the documentation of picamera and it could be that its trying to run in python 2.
But I found the solution to be the following:
You need to have the following packages installed: python-picamera & python3-picamera
So running:
sudo apt-get install python-picamera fixed it
Trying to implement an Item Loader.
my class name in items.py:
SiemensLinkcontentItem
my import statements inside my spider:
import scrapy
from scrapy.loader import ItemLoader
from siemens_linkcontent.siemens_linkcontent.items import SiemensLinkcontentItem
I get the following error:
No module named 'siemens_linkcontent.siemens_linkcontent'
My path diagramm is the following:
Use This One
- from siemens_linkcontent.items import SiemensLinkcontentItem
I installed JPype in a correct way and anything is fine and my instalation was succeed but when i run my refactor.py from command prompt i have error that i pointed in title.
i hope you can help me for solving this problem.
also i have to point that i am beginner in python3.
here is my code:
import urllib.request
import os
import tempfile
import sys
import fileinput
import logging
import jpype
logging.basicConfig(filename="ERROR.txt", level= logging.ERROR)
try:
logging.debug('we are in the main try loop')
jpype.startJVM("C:/Users/user/AppData/Local/Programs/Python/Python36/ClassWithTest.java", "-ea")
test_class = jpype.JClass("ClassWithTest")
a = testAll()
file_java_class = open("OUTPUT.txt", "w")
file_java_class.write(a)
except Exception as e1:
logging.error(str(e1))
jpype.shutdownJVM()
startJVM() function takes the path to the JVM which is like this - C:\\Program Files\\Java\\jdk-10.0.2\\bin\\server\\jvm.dll. You could use the getDefaultJVMPath() function to get the JVM path on your PC. So you can just start the JVM this way:
startJVM(getDefaultJVMPath(), "-ea")
Hope that helps!
I'm trying to use the NASDAQ API from https://github.com/Nasdaq/DataOnDemand but cannot seem to get it to work in Python 3.
I fixed the urllib stuff and first got an error at line 92 which I fixed by encoding it to utf-8
Before:
request_parameters = urllib.parse.urlencode(values)
Fix:
request_parameters = urllib.parse.urlencode(values).encode('utf-8')
But now i get an error on:
response = urllib.request.urlopen(req)
>>>TypeError: cannot use a string pattern on a bytes-like object
When i try to fix it by decoding i get:
response = urllib.request.urlopen(req).decode()
OR
response = urllib.request.urlopen(req).decode('utf-8')
>>>AttributeError: 'HTTPResponse' object has no attribute 'decode'
This is what my imports look like:
import urllib.request
import urllib.parse
import xml.etree.cElementTree as ElementTree
import re
from pprint import pprint
import matplotlib.dates as mdates
import matplotlib.pyplot as plt
import datetime as dt
Any help is appreciated
