$1.$ Input Handling:

$$ Implement functionality to read user inputs for transaction details, including type of transaction $($income or expenses$),$ amount, category, date, and associated account.

$$ Users should have the option to select transaction categories from a predefined list and also add new categories to this list.

$$ Utilize the input$()$ function for interactive inputs or opt for file reading $($e$.$g$.,$ CSV$)$ for batch inputs.

$$ Users should have the option to select the type of account associated with the transaction record, including options such as "savings account," "checking account," or "credit card."

$$ Users should be able to input the transaction date when recording their transactions.

Example of User Inputs:

For each transaction, the user should provide:

$$ Type: 'Income' or 'Expense' $-$ Indicates whether the transaction is adding to or subtracting from the user's funds.

$$ Amount: A numerical value representing the amount of the transaction. For example, $1200\mathrm{.}50$ for an income of $$1,200\mathrm{.}50$ or $39\mathrm{.}99$ for an expense of $$39\mathrm{.}99.$

$$ Category: A string representing the category of the transaction. For example, 'Salary', 'Groceries', 'Utilities'.

$$ Date: The date of the transaction in a recognized format, such as YYYY$-$MM$-$DD$.$
