Python Tkinter Random Number Generator Using Random Library GUI Desktop App Full Project For Beginners

Python Tkinter Random Number Generator Using Random Library GUI Desktop App Full Project For Beginners


Welcome folks today in this blog post we will be generating random number  inside tkinter gui desktop app in python using random library. All the full source code of the application is shown below.



Get Started



In order to get started we need to install the following library using the pip command as shown below


pip install random


After installing this library you need to make an file and copy paste the following code


import tkinter as tk
from tkinter import ttk
import random

class App:

    def __init__(self, master):
        self.master = master
        self.master.title("Random Number Generator")
        self.master.resizable(True, True)

        self.font = ("arial", 11)


    def create_gui(self):
        self.main_frame = tk.Frame(self.master)
        self.main_frame.grid(row=0, column=0)

        self.min_label = tk.Label(self.main_frame, text="min: ", font=self.font)
        self.min_label.grid(row=0, column=0)

        self.min_entry = ttk.Entry(self.main_frame)
        self.min_entry.grid(row=0, column=1, padx=5, pady=2)

        self.max_label = tk.Label(self.main_frame, text="max: ", font=self.font)
        self.max_label.grid(row=1, column=0)

        self.max_entry = ttk.Entry(self.main_frame)
        self.max_entry.grid(row=1, column=1, padx=5, pady=2)

        self.stepsize_label = tk.Label(self.main_frame,
                                       text="stepsize: ", font=self.font)
        self.stepsize_label.grid(row=2, column=0)

        self.stepsize_entry = ttk.Entry(self.main_frame, text="1")
        self.stepsize_entry.grid(row=2, column=1, padx=5, pady=2)

        self.generate_button = ttk.Button(self.main_frame, text="generate",
                                          command=lambda: self.generate_number())
        self.generate_button.grid(row=3, column=0)

        self.result_label = tk.Label(self.main_frame, text="result: ", font=self.font)
        self.result_label.grid(row=3, column=1)

    def generate_number(self):
            min_threshold = float(self.min_entry.get())
            max_threshold = float(self.max_entry.get())
            stepsize = float(self.stepsize_entry.get())
            random_number = random.randrange(min_threshold, max_threshold, stepsize)
            self.result_label.config(text="result: {}".format(random_number))
        except Exception as e:

if __name__ == "__main__":
    root = tk.Tk()
    app = App(root)

And now if you execute the above python script by typing the below command as shown below





As you can see we have generated the random number between 10 and 100 which is 86
