Q & A

What is the main purpose of the Python project discussed in the script?

The main purpose of the Python project is to build a personal finance tracker that can track and log different transactions, organize them, provide summaries of income and expenses, and visualize the data in a graph to analyze financial trends over time.

Which Python modules are mentioned as essential for this project?

The essential Python modules mentioned for this project are Matplotlib and pandas. Matplotlib is used for plotting graphs, and pandas is used for data manipulation and analysis.

How does the personal finance tracker store its data?

The personal finance tracker stores its data in a CSV file, which acts as a simple database. This file contains columns for date, amount, category, and description of each transaction.

What features does the personal finance tracker allow a user to perform?

The personal finance tracker allows users to add new transactions, view transactions within a specified date range, summarize income and expenses, and plot the data to visualize financial trends.

How is the date format handled in the script when adding a new transaction?

The date format is handled by using a specific format (day, month, year) and validating the input to ensure it matches this format. If the input is not valid, the user is prompted to re-enter the date in the correct format.

What is the role of the 'data_entry.py' file in the project?

The 'data_entry.py' file contains functions for collecting and validating user input, such as dates, amounts, categories, and descriptions for transactions. It helps to organize the code and keep the main file cleaner.

How does the script handle the creation of the CSV file if it doesn't exist?

The script checks if the CSV file exists using pandas' read_csv function. If a FileNotFoundError occurs, it catches the exception and creates a new CSV file with the specified columns using pandas' DataFrame.

What is the significance of using a class in the script for handling CSV file operations?

Using a class for handling CSV file operations encapsulates the functionality related to the CSV file within a single entity, making the code more organized and adhering to object-oriented programming principles.

How does the script ensure that the user inputs valid data for transactions?

The script uses validation functions for each type of input (date, amount, category, description). These functions repeatedly prompt the user until the input is valid, ensuring data integrity.

What is the purpose of the 'plot_transactions' function in the script?

The 'plot_transactions' function is used to visualize the financial data. It takes a filtered DataFrame of transactions, sets the date as the index, and uses Matplotlib to create a line plot showing income and expenses over time.
