##Explanation:
##Initialization: Creates a CSV file with headers if it doesn’t exist.

##Adding Entries: Appends a new budget entry to the CSV file.

##Viewing Entries: Reads and prints all budget entries from the CSV file.

##Summarizing Entries: Summarizes budget entries by category and type (income or expense) and prints totals.

##Enhancements:
##User Input: Modify the script to take input from users for adding entries.

##Date Filters: Add functionality to filter entries by date.

##Advanced Analysis: Use libraries like pandas for more complex data analysis and visualization.
