bookChallenge 4: Handling Missing Values

Managing gaps in your datasets is a task that no data scientist can overlook. In this area, NumPy offers an extensive set of tools. Whether it's detecting, removing, or filling missing values, NumPy has functionalities tailored to handle these tasks with ease.

Employing NumPy's capabilities in handling missing values not only refines your datasets but also paves the way for a more robust and reliable analysis, a cornerstone in data science undertakings.

Task

Sometimes, datasets might have missing or non-numeric values. Handle them efficiently with numpy.

  1. Check for the presence of NaN values. Set True if NaN exists, False if not.
  2. Replace NaN values with 0.
