Example Usage

from graphs import Graphs

g = Graphs(
    title="Animal Balance",
    theme="ggplot"
)

g.pie_chart(
    labels=["Humans", "Animals", "Insects"],
    values=[80, 50, 40]
)

g.bar_graph(
    labels=["Humans", "Animals", "Insects"],
    values=[80, 50, 40]
)

g.horizontal_bar_graph(
    labels=["Humans", "Animals", "Insects"],
    values=[80, 50, 40]
)

Password Entry Module

A lightweight Tkinter-based password prompt utility that creates a simple GUI window for password input and validation.

Example Usage

from password_entry import start_password_entry

start_password_entry(
    required="mysecretpassword"
)

Function Reference

start_password_entry(required="abcd1234")

Creates a password entry window and validates user input against the required password.

Parameters

Default Value

required="abcd1234"

Basic Usage

from password_entry import start_password_entry

start_password_entry()

Uses the default password:

abcd1234

Custom Password

from password_entry import start_password_entry

start_password_entry(
    required="admin123"
)

How It Works

1. Creates a Tkinter window.
2. Displays a password input field.
3. Masks entered characters using *.
4. Waits for the user to press Submit.
5. Compares the entered password with the required password.

Source Example

from tkinter import *

def start_password_entry(required="abcd1234"):
    root = Tk()
    root.title("Enter your password")

    password = Entry(root, show="*")
    password.pack()

    def submit():
        passw = password.get()

        if passw == required:
            return True
        else:
            return False

    Button(root, text="Submit", command=submit).pack()

    root.mainloop()

Notes

• Password characters are hidden while typing.
• Built using Python's standard Tkinter library.
• The current implementation validates the password but does not display success or failure messages.
• Can be extended with dialogs, callbacks, or custom UI elements.
