Messy Data, Real People

The situation

Code Nexus's first creator report has duplicate handles, names with accented characters that sort oddly, and a few records missing a key field. Amara asks the question she always asks first: is this data fit for the job?

What you'll learn

• PCEP 3.1-3.4: lists, tuples, dictionaries, strings, slicing, membership, copying (aliasing), comprehensions, and nested collections.
• String escapes and triple-quoted strings, list.insert() and index(), and two-dimensional lists.

1. 1.Fit for purpose?
2. 2.Predict the slice
3. 3.Clean the records
4. 4.The list that changed itself
5. 5.Collections check

What you leave with

You can read slices and membership without running the code, you de-duplicated the records and recorded missing values as missing instead of guessing, and you found why two creators' tag lists were bleeding into each other.
