Lære Summarizing Business Data | Business Data Manipulation

In business analysis, summarizing data is essential for uncovering trends, identifying opportunities, and making informed decisions. Common business metrics include total sales, average revenue per product, total units sold, and product-wise performance. By aggregating raw data, you can quickly answer questions such as "Which product generated the most revenue?" or "What is the average sale per transaction?" Summarization helps you focus on the big picture rather than getting lost in granular details, ensuring you deliver actionable insights to stakeholders.

# Sample cleaned sales dataset
sales_data = [
    {"product": "Laptop", "units_sold": 5, "revenue": 5000},
    {"product": "Smartphone", "units_sold": 10, "revenue": 7000},
    {"product": "Laptop", "units_sold": 3, "revenue": 3000},
    {"product": "Tablet", "units_sold": 8, "revenue": 4000},
    {"product": "Smartphone", "units_sold": 6, "revenue": 4200},
]

# Calculate total revenue and units sold for each product
summary = {}
for row in sales_data:
    product = row["product"]
    if product not in summary:
        summary[product] = {"total_units": 0, "total_revenue": 0}
    summary[product]["total_units"] += row["units_sold"]
    summary[product]["total_revenue"] += row["revenue"]

for product, stats in summary.items():
    print(f"{product}: {stats['total_units']} units, ${stats['total_revenue']} revenue")

The aggregation logic behind summarizing business data involves grouping entries by a key, such as product name, and then performing calculations like summing units_sold or total_revenue. This process typically starts by iterating through your dataset, checking the product for each transaction, and updating running totals. The results are stored in a summary dictionary, where each key is a product and the value is another dictionary holding its aggregated statistics. This approach allows you to rapidly access summary metrics for any product, supporting deeper business insights and reporting.

for entry in sales_data:
    product = entry["product"]
    if product not in product_summary:
        product_summary[product] = {"units_sold": 0, "revenue": 0}
    product_summary[product]["units_sold"] += entry["units_sold"]
    product_summary[product]["revenue"] += entry["revenue"]

print(product_summary)
