Run2 csv reporting

Reliable CSV Reporting

This skill focuses on clean and error-free CSV generation.

Best Practices

• Use csv.DictWriter for clarity and automatic field alignment.
• Always specify newline='' when opening the file to avoid blank lines on some platforms.
• Ensure all dictionary keys match the fieldnames list exactly.

import csv

def generate_csv_report(data_list, output_file):
    if not data_list:
        print("No data to write to CSV.")
        return

    fieldnames = list(data_list[0].keys())
    with open(output_file, 'w', newline='', encoding='utf-8') as f:
        writer = csv.DictWriter(f, fieldnames=fieldnames)
        writer.writeheader()
        writer.writerows(data_list)
