Problem with PyQt5, how to fix the error?

Question

PyQt

I decided to make a simple generator application with a GUI on PyQt5, but an error appeared.

Here is the code itself:

import sys
import os
from PyQt5.QtCore import pyqtSlot
from PyQt5.QtWidgets import *
from PyQt5.uic import loadUi
import random, string
import time

class p_main(QWidget):
  def __init__(self):
    super(p_main, self).__init__()
    loadUi("uno.ui", self)
    self.PushButton.clicked.connect(gen)

  def gen():
    value = 1
    while value <= amount:
        code = "https://discord.gift/" + ('').join(random.choices(string.ascii_letters + string.digits, k=16))
        value += 1
        self.Label.setText(code)

app = QApplication(sys.argv[:1])
wind = p_main(QWidget)
wind.show()
sys.exit(app.exec_())

And here is the error:

Traceback (most recent call last):
  File "C:\Users\Desmoke\Desktop\5.py", line 23, in <module>
    wind = p_main(QWidget)
TypeError: __init__() takes 1 positional argument but 2 were given

Answer 1

It started like this for me ... True, only an empty window. I don't have "uno.ui"

import sys
import os
from PyQt5.QtCore import pyqtSlot
from PyQt5.QtWidgets import *
from PyQt5.uic import loadUi
import random, string
import time

class p_main(QWidget):
  def __init__(self):
    super().__init__()
    #loadUi("uno.ui", self)
    #self.PushButton.clicked.connect(gen)

  def gen():
    value = 1
    while value <= amount:
        code = "https://discord.gift/" + ('').join(random.choices(string.ascii_letters + string.digits, k=16))
        value += 1
        self.Label.setText(code)

app = QApplication(sys.argv[:1])
wind = p_main()
wind.show()
sys.exit(app.exec_())
