Script 561: Pacing Start & End Date

Purpose:

The Python script extracts and updates pacing start and end dates from campaign names in a dataset.

To Elaborate

The Python script is designed to parse campaign names to extract pacing start and end dates, which are then formatted into ISO date format (YYYY-MM-DD). It identifies campaigns with changed pacing dates and updates the dataset accordingly. The script handles various campaign name formats, including those with optional spaces and parentheses, ensuring robust date extraction. The primary goal is to maintain accurate pacing information for campaigns by detecting changes and updating the relevant fields in the dataset.

Walking Through the Code

  1. Initialization and Setup:
    • The script begins by defining constants for column names related to campaigns and pacing dates.
    • Temporary columns are created in the input DataFrame to store parsed start and end dates, initialized with NaN values.
  2. Date Extraction Function:
    • A function get_dates_from_campaign_name is defined to extract start and end dates from the campaign name using regular expressions.
    • The function attempts to parse dates in both four-digit and two-digit year formats, defaulting to NaN if parsing fails.
  3. Testing Date Extraction:
    • A test function test_get_dates_from_campaign_name is implemented to verify the date extraction logic against various campaign name formats.
    • The test ensures that the function correctly parses dates and handles different formatting scenarios.
  4. Parsing and Updating DataFrame:
    • The script iterates over each row in the input DataFrame, applying the date extraction function to populate the temporary columns with parsed dates.
    • It identifies campaigns with changed pacing dates by comparing parsed dates with existing ones.
  5. Output Preparation:
    • Changed campaigns are selected, and their relevant columns are copied to a new DataFrame, with temporary columns renamed to bulk column names.
    • The script checks if the output DataFrame is empty and prints the results accordingly.
