alguiloop 1.0.5

A python package which allows to use while and for loops without obstructing the GUI. This is currently for tkinter, PyQt5, PyQt6, wxPython, PyForms-GUI and PySide2.

AlGUILoop

AlGUILoop allows to use while and for loops alongside without obstructing the GUI. This is currently for tkinter, PyQt5, PyQt6, wxPython, PyForms-GUI and PySide2.

Installation

You can install AlGUILoop from PyPI: pip install alguiloop.

The AlGUILoop supports Python 3.6 and above.

Usage

There are following examples to use while and for loops alongside without obstructing the GUI using AlGUILoop :-

"""
