Error in code within Documentation

[zdavidwade]

In the documentation for CIK, CUSIP, Ticker Mapping API. The Example : Python presents code to identify all active Nasdaq (and later NYSE) traded entities. The specific line of code with the error is:

nasdaq_listings_active = all_nasdaq_listings[all_nasdaq_listings['isDelisted'] != False]

This returns results for entities where isDelisted = True. These firms are no longer active. The results presented are the correct outputs for the code, but are incorrectly attributed as active entities. This error persists as the bar chart included is therefore incorrect. This may lead to misinterpreted results.
