Creating a Finance Tracker App using Speedcode in Python/Kivy

Creating a finance tracker app can be a great way to keep track of your expenses, income, and overall financial health. In this tutorial, we will be building a finance tracker app using Python and Kivy, a Python framework for building mobile apps.

To get started, you will need to have Python and Kivy installed on your system. You can download Python from the official website (https://www.python.org/downloads/) and install it on your computer. After installing Python, you can install Kivy by running the following command in your terminal or command prompt:

pip install kivy

Once you have Python and Kivy installed, you can start building your finance tracker app. The app will have multiple screens for displaying your expenses, income, and overall financial summary. We will also include functionality for adding new expenses and income entries.

1. Setting up the project:
   Create a new folder for your finance tracker app project and navigate to that folder in your terminal or command prompt. Create a new Python file named ‘main.py’ for your main application code.

2. Importing the necessary modules:
   In the ‘main.py’ file, import the necessary modules for building the app:

from kivy.app import App
from kivy.uix.screenmanager import ScreenManager, Screen
from kivy.uix.label import Label
from kivy.uix.button import Button
from kivy.uix.textinput import TextInput

1. Creating the main app class:
   Define a class for your finance tracker app that inherits from the ‘App’ class provided by Kivy:

class FinanceTrackerApp(App):
    def build(self):
        pass

if __name__ == '__main__':
    FinanceTrackerApp().run()

1. Creating screens for expenses, income, and summary:
   Create classes for each screen in your app, including the expenses screen, income screen, and summary screen. Each screen will display relevant information and allow users to add new entries.

class ExpensesScreen(Screen):
    def __init__(self, **kwargs):
        super().__init__(**kwargs)

        self.add_button = Button(text='Add Expense')
        self.add_button.bind(on_press=self.add_expense)

        self.add_widget(self.add_button)

    def add_expense(self, instance):
        pass

class IncomeScreen(Screen):
    def __init__(self, **kwargs):
        super().__init__(**kwargs)

        self.add_button = Button(text='Add Income')
        self.add_button.bind(on_press=self.add_income)

        self.add_widget(self.add_button)

    def add_income(self, instance):
        pass

class SummaryScreen(Screen):
    def __init__(self, **kwargs):
        super().__init__(**kwargs)

        self.total_expenses = Label(text='Total Expenses: $0.00')
        self.total_income = Label(text='Total Income: $0.00')
        self.balance = Label(text='Balance: $0.00')

        self.add_widget(self.total_expenses)
        self.add_widget(self.total_income)
        self.add_widget(self.balance)

1. Creating the screen manager:
   Create a screen manager to switch between the expenses, income, and summary screens. Add the screens to the screen manager and set the initial screen to the expenses screen.

class FinanceTrackerManager(ScreenManager):
    def __init__(self, **kwargs):
        super().__init__(**kwargs)

        self.expenses_screen = ExpensesScreen(name='expenses')
        self.income_screen = IncomeScreen(name='income')
        self.summary_screen = SummaryScreen(name='summary')

        self.add_widget(self.expenses_screen)
        self.add_widget(self.income_screen)
        self.add_widget(self.summary_screen)

        self.current = 'expenses'

1. Running the app:
   Finally, create an instance of your finance tracker app and run it:

class FinanceTrackerApp(App):
    def build(self):
        return FinanceTrackerManager()

if __name__ == '__main__':
    FinanceTrackerApp().run()

You now have a basic finance tracker app that allows users to switch between expenses, income, and summary screens. You can add functionality for adding new expenses and income entries by implementing the ‘add_expense’ and ‘add_income’ methods in the ExpensesScreen and IncomeScreen classes.

This tutorial provides a starting point for building a finance tracker app with Python and Kivy. You can further customize the app by adding more features, such as data visualization, budget planning, and expense categories. Experiment with different layouts, styles, and functionalities to create a finance tracker app that suits your needs.
