Introduction to Financial Data Structures
In banking, you work with a variety of financial data types, such as transaction records, account balances, and customer profiles. Transactions include details like the date, amount, and type (deposit, withdrawal, transfer). Balances track the current amount in accounts, while customer information includes names, addresses, and account numbers. Organizing this information in a structured way is essential for accurate reporting, compliance, fraud detection, and decision-making. When data is well-structured, you can efficiently search, filter, aggregate, and analyze it using Python tools, which is critical for modern banking operations.
12345678910# Representing a list of bank transactions as a list of dictionaries transactions = [ {"date": "2024-06-01", "amount": 1000.00, "type": "deposit"}, {"date": "2024-06-03", "amount": -200.00, "type": "withdrawal"}, {"date": "2024-06-05", "amount": -50.00, "type": "fee"}, {"date": "2024-06-07", "amount": 500.00, "type": "deposit"}, {"date": "2024-06-10", "amount": -300.00, "type": "withdrawal"} ] print(transactions)
While a list of dictionaries is useful for storing transaction data, it can become difficult to analyze as the dataset grows. To make analysis easier, you can convert the list of dictionaries into a pandas DataFrame. DataFrames provide powerful tools for sorting, filtering, and summarizing financial records, making it much simpler to generate reports or spot trends in banking data.

1. What is the main advantage of using a pandas DataFrame for financial data analysis in banking?
2. Which Python data structure is best suited for storing a single customer's transaction history?
3. Why is it important to structure financial data before analysis?

How can I filter transactions by type or date in the DataFrame?
Can you show me how to calculate the total balance from these transactions?
What are some common analyses I can perform on this banking data using pandas?
Fantastisk!
