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)

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

How to read grayscale img from a video with OpenCV?

I read all pictures from my pic directory and then convert them each to gray-scale with canny edge detections before writing it all to a video.

But, when I use my video software to play it, it shows a green background, and I can't read video frames from it. Could someone show me how to solve it?

Sample code

import numpy as np
import cv2 as cv
import matplotlib.pyplot as plt

fourcc = cv.VideoWriter_fourcc(*"I420")
out = cv.VideoWriter("t2.avi", fourcc, 1, (640, 480), 0)
for pic in glob.glob1("./pic/", "A*"):
    img = cv.imread(f"./pic/{pic}", -1)
    
    edge = cv.Canny(img, 100, 200)
    edge = cv.resize(edge, (640, 480))
    out.write(edge)

out.release()

# Cant read video frame here:
cap = cv.VideoCapture("t2.avi")
ret, frame = cap.read()
if ret:
    plt.imshow(frame)
else:
    print("end")
    cap.release()

Video plays with green background

Is there a way to guarantee a certain number of lines detected with cv2.HoughLines()?

This question is an extension to my previous question asking about how to detect a pool table's corners. I have found the outline of a pool table, and I have managed to apply the Hough transform on the outline. The result of this Hough transform is below:

Unfortunately, the Hough transform returns multiple lines for a single table edge. I want the Hough transform to return four lines, each corresponding to an edge of the table given any image of a pool table. I don't want to tweak the parameters for the Hough transform method manually (because the outline of the pool table might differ for each image of the pool table). Is there any way to guarantee four lines to be generated by cv2.HoughLines()?

Thanks in advance.
I am working on a small project in C++ with GUI, which is about calculating the age. I want to make my program work on other computers

I am using Visual Studio 2013, I finished my project and I need to publish it, the problem is that it does not work on other computer, I think, because of the static link library or the like.I used reserved libraries in the language like time.h , MyForm.h and did not use external libraries, I need solution to my problem, if there are references to something similar, mention them.

EDIT: Sorry for the ambiguity in my question,

clarification: When I tried to run my program in another machine, an error message appeared, which means that the system did not recognize the file.EXE, I did not do the release, I just did Debug and then the .exe file in the Debug folder Sent it to other computers.

Sorry for bad English.

Thank you.

AttributeError: 'str' object has no attribute 'tk' when click button

Here is my code:


window = tk.Tk()


version = tk.Label(text="hi",
                   fg="orange",
                   bg="black",
                   width=20,
                   height=10,
                   )
version.pack()
enter = tk.Button(text="START",fg="blue",width=20,height=7)
enter.pack()

def click(event):
    version.forget()
    enter.forget()
    name = tk.Label("name")
    entry = tk.Entry()
    name.pack()
    entry.pack()


enter.bind("<Button-1>", click)



window.mainloop()

As you can see, I wanted to make a Label and an Entry appear once the START button is clicked.

When I click the button, though, it returns this error:

Storyboard mirroring after localization in iOS

I have an iOS app. I started working on it without localization. The app is RTL-language-oriented. Now I wanted to localize the app so I created localization of strings. I didn't add any storyboard localization.

But unfortunately, all the UI got mirrored.

I don't even have "main(base)" file

The question is - Why is my UI NOT ignoring the language direction like it did before I started localizing? I expect the UI to ignore the language direction because I didn't add anything that should change the behavior it had before starting the localization.

(I know about the "right-leading left-trailing + respect language direction" ability of constraints, this is not my question)

Thank you!

What is the reason of this error I'm getting when using tkinter for a math app

Im making a program that will do most of my homework. Im trying to add some ui and it gives errors in my code. Please tell what's wrong. Make it easy enough for a 13 year old to understand because I'm new to python. This gives an error only when i use canvas. If i use window, then it doesn't but i want to use canvas because I can change their position more accurately

from tkinter import *

root=Tk()
canvas1 = Canvas(root, width = 400, height = 300)
canvas1.pack()
entry1 = Entry (root) 
canvas1.create_window(200, 140, window=entry1)
entry2 = Entry (root) 
canvas1.create_window(200, 180, window=entry2)
entry3 = Entry (root) 
canvas1.create_window(200, 220, window=entry3)

def getvalue():
      p=entry1.get()
      r=entry2.get()
      t=entry3.get()      
      labelans = Label(root, text = float(p*r*t)/100)
      canvas1.create_window(200, 230, window=labelans)

label1 = Label(root, text="Time")
canvas1.create_window(437, 220, window=label1)
label2 = Label(root, text="Rate")
canvas1.create_window(437,180, window=label2)
label3 = Label(root, text="Principal")
canvas1.create_window(465, 140, window=label3)

button1 = Button(text='Solve!', bg="red", command=getvalue)
canvas1.create_window(200, 300, window=button1)

mainloop()

How to use Tkinter after method to give the impression of a wheel spinning?

I'm trying to create three separate 'wheels' that change the starting position of the first arc in order to give the impression of the wheel spinning. Tkinter will draw the first wheel on the canvas and delete it after 1 second, but the subsequent wheels are never drawn.

    from tkinter import Canvas, Tk

    tk = Tk()
    tk.geometry('500x500')

    canvas = Canvas(tk)
    canvas.pack(expand=True, fill='both')

    in_list = [1,1,1,1,1,1,1]

    arc_length = 360 / len(in_list)
    first_mvmt = arc_length / 3
    second_mvmt = arc_length * 2 / 3

    mvmt_list = [0, first_mvmt, second_mvmt]

    for mvmt in mvmt_list:
        for i in range(len(in_list)):
            start = i * arc_length
            extent = (i + 1) * arc_length
            arc = canvas.create_arc(5, 5, 495, 495, outline='white', start=start + mvmt, extent=extent)

        canvas.after(1000)
        canvas.delete('all')


    tk.mainloop()
