Hello everyone. I've created another User Interface to Python converter (you can find the first one here, though I don't recommend it, it's ugly), this one's more simple and comfortable. Literally all you have to do is drag the *.ui file and drop it in the square, the *.py file will be generated in the directory that you choose (Desktop by default). I've attached the icon, even thought it's not necessary, and also, the program will create a "settings.txt" file, which contains the path where the generated file should be saved.

Here's the code:

from PyQt5 import QtCore, QtGui, QtWidgets
from pathlib import Path
import os

savePath = ""
settingsFilePath = Path("settings.txt")

if not settingsFilePath.is_file():
    f = open("settings.txt", "w")
    savePath = os.environ["HOMEPATH"] + "\\Desktop\\"
    f.write(savePath)
    f.close()
else:
    f = open("settings.txt", "r")
    savePath = f.readline()
    f.close()

def convertToPy(target):
    os.system('pyuic5 -o "' + savePath + '/convertedfile.py" "' + target + '"')

class Label(QtWidgets.QLabel):
    def __init__(self):
        super(Label, self).__init__()

        self.setAcceptDrops(True)

    def dragEnterEvent(self, e):
        if e.mimeData().hasFormat("text/uri-list"):
            e.accept()
        else:
            e.ignore()

    def dropEvent(self, e):
        convertToPy(e.mimeData().text()[8:])

class MainWindow(QtWidgets.QWidget):
    def __init__(self):
        super().__init__()

As always, I want to hear your opinion, did I do a good job? Please do comment on my code.

Thanks and enjoy! 

Edit:

For some reason, the code is not indented, here's a gist.
