Example of an interesting technical problem in Python:

Optimizing large data processing I needed to process a large CSV file (several gigabytes) that couldn't fit into memory. The task was to calculate statistics for certain columns.

Solution:

• Used generators and the csv module for line-by-line processing.
• Applied dictionaries to count aggregates.
• Optimized the code to minimize memory usage and speed up processing.

Code example:

import csv

def process_large_csv(file_path):
    stats = {}
    with open(file_path, newline='') as csvfile:
        reader = csv.DictReader(csvfile)
        for row in reader:
            key = row['category']
            value = int(row['value'])
            stats[key] = stats.get(key, 0) + value
    return stats

This approach allowed efficient data processing without loading the entire file into memory.
