I have a single CSV that needs a quick but reliable scrub in Python. The job is straightforward: • Identify and drop all duplicate rows. • Remove every row that contains at least one missing value (I don’t need any imputation on this file). • Standardise every date column to the same format—yyyy-mm-dd—so downstream tools read them consistently. Please send back a well-commented .py script (Pandas is fine) along with the cleaned CSV so I can rerun the process whenever new data arrives. A short README outlining how to execute the script is all the documentation I need.
