Can't add item to QLIstWidget

2022-05-04 10:49 Kaja Koenders imported from Stackoverflow

Trying to add an item to a QListWidget but it won't add the item to the list.

code:

dirListLayout = QListWidget()
 def dropped(dir):
      dirListLayout.addItem(dir)
            
      print("dropped and added")

dir is a string "test" in this case.

It doesn't show any error. it does print "dropped and added"

Thanks in advance.

Python File Tagging System does not retrieve nested dictionaries in dictionary

I am building a file tagging system using Python. The idea is simple. Given a directory of files (and files within subdirectories), I want to filter them out using a filter input and tag those files with a word or a phrase.

If I got the following contents in my current directory:

data/
   budget.xls
   world_building_budget.txt
a.txt
b.exe
hello_world.dat
world_builder.spec

and I execute the following command in the shell:

py -3 tag_tool.py -filter=world -tag="World-Building Tool"

My output will be:

These files were tagged with "World-Building Tool":
data/ world_building_budget.txt
hello_world.dat
world_builder.spec

My current output isn't exactly like this but basically, I am converting all files and files within subdirectories into a single dictionary like this:

def fs_tree_to_dict(path_):
    file_token = ''
    for root, dirs, files in os.walk(path_):
        tree = {d: fs_tree_to_dict(os.path.join(root, d)) for d in dirs}
        tree.update({f: file_token for f in files})
        return tree

Right now, my dictionary looks like this: key:''.

In the following function, I am turning the empty values '' into empty lists (to hold my tags):

def empty_str_to_list(d):
    for k,v in d.items():
        if v == '':
            d[k] = []
        elif isinstance(v, dict):
            empty_str_to_list(v)

When I run my entire code, this is my output:

hello_world.dat ['World-Building Tool']
world_builder.spec ['World-Building Tool']

But it does not see data/world_building_budget.txt. This is the full dictionary:

{'data': {'world_building_budget.txt': []},  
'a.txt': [],
'hello_world.dat': [], 
'b.exe': [], 
'world_builder.spec': []}

This is my full code:

import os, argparse


def fs_tree_to_dict(path_):
    file_token = ''
    for root, dirs, files in os.walk(path_):
        tree = {d: fs_tree_to_dict(os.path.join(root, d)) for d in dirs}
        tree.update({f: file_token for f in files})
        return tree


def empty_str_to_list(d):
    for k, v in d.items():
        if v == '':
            d[k] = []
        elif isinstance(v, dict):
            empty_str_to_list(v)


parser = argparse.ArgumentParser(description="Just an example", formatter_class=argparse.ArgumentDefaultsHelpFormatter)

parser.add_argument("--filter", action="store", help="keyword to filter files")
parser.add_argument("--tag", action="store", help="a tag phrase to attach to a file")
parser.add_argument("--get_tagged", action="store", help="retrieve files matching an existing tag")

args = parser.parse_args()

filter = args.filter
tag = args.tag
get_tagged = args.get_tagged
current_dir = os.getcwd()

files_dict = fs_tree_to_dict(current_dir)
empty_str_to_list(files_dict)

for k, v in files_dict.items():
    if filter in k:
        if v == []:
            v.append(tag)
            print(k, v)

        elif isinstance(v, dict):
            empty_str_to_list(v)

    if get_tagged in v:
        print(k, v)

Actaully i am working on a project and in it, it is showing no module name pip_internal plz help me for the same. I am using pycharm(conda interpreter

Looping the function if the input is not string

I'm new to python (first of all) I have a homework to do a function about checking if an item exists in a dictionary or not.

inventory = {"apple" : 50, "orange" : 50, "pineapple" : 70, "strawberry" : 30}

def check_item():
    x = input("Enter the fruit's name: ")
    if not x.isalpha():
        print("Error! You need to type the name of the fruit")
    elif x in inventory:
        print("Fruit found:", x)
        print("Inventory available:", inventory[x],"KG")
    else:
        print("Fruit not found")
check_item()

I want the function to loop again only if the input written is not string. I've tried to type return Under print("Error! You need to type the name of the fruit") but didn't work. Help

PyQT5 doesn't work on docker ImportError: libsmime3.so: cannot open shared object file: No such file or directory

I have a Dockerfile with PyQT installed like below

FROM ubuntu:20.04
ENV DEBIAN_FRONTEND=noninteractive
RUN adduser --quiet --disabled-password qtuser && usermod -a -G audio qtuser
RUN apt-get update -y \
    && apt-get install alsa -y \
    && apt-get install -y python3-pyqt5 \
    && apt-get install python3-pip -y && \
    pip3 install pyqtwebengine
WORKDIR /htmltopdf

I built my image like this docker build -t html-to-pdf .

Then I ran my image like this docker run --rm -v "$(pwd)":/htmltopdf -u qtuser -it html-to-pdf python3 htmlToPdfnew.py --url https://www.w3schools.com/howto/howto_css_register_form.asp

But I'm getting below error

Traceback (most recent call last):
  File "htmlToPdfnew.py", line 2, in <module>
    from PyQt5 import QtWidgets, QtWebEngineWidgets
ImportError: libsmime3.so: cannot open shared object file: No such file or directory

I do NOT get that error in my PC.

below is my python code

import sys
from PyQt5 import QtWidgets, QtWebEngineWidgets
from PyQt5.QtCore import QUrl, QTimer
from PyQt5.QtGui import QPageLayout, QPageSize
from PyQt5.QtWidgets import QApplication
import argparse


def main():
    url = ''
    parser = argparse.ArgumentParser(description="Just an example", formatter_class=argparse.ArgumentDefaultsHelpFormatter)
    parser.add_argument("--url", help="Type url")
    args = parser.parse_args()
    config = vars(args)
    url = config['url']


    app = QtWidgets.QApplication(sys.argv)
    loader = QtWebEngineWidgets.QWebEngineView()
    loader.setZoomFactor(1)
    layout = QPageLayout()
    layout.setPageSize(QPageSize(QPageSize.A4Extra))
    layout.setOrientation(QPageLayout.Portrait)
    loader.load(QUrl(url))
    loader.page().pdfPrintingFinished.connect(lambda *args: QApplication.exit())

    def emit_pdf(finished):
        QTimer.singleShot(2000, lambda: loader.page().printToPdf("test.pdf", pageLayout=layout))

    loader.loadFinished.connect(emit_pdf)
    sys.exit(app.exec_())

if __name__ == '__main__':
    main()

so how do I resolve below error ?

Traceback (most recent call last):
  File "htmlToPdfnew.py", line 2, in <module>
    from PyQt5 import QtWidgets, QtWebEngineWidgets
ImportError: libsmime3.so: cannot open shared object file: No such file or directory

to import pyqt5.uic, do I have to install pyqt5-tools first?

(venv) PS C:\Users\77140\AppData\Roaming\Anki2\addons21\myaddon> pip freeze | grep PyQt
PyQt5-Qt5==5.15.2
PyQt5-sip==12.10.1
PyQt5-stubs==5.15.6.0
PyQtWebEngine==5.15.5
PyQtWebEngine-Qt5==5.15.2

But My python version is 3.10, from pyqt5-tools offical site, it doesn't support python 3.10, is it why when I exec pip install pyqt5-tools, always get the below error?:

Thanks a lot.
