In Python’s standard library, what packages would you say are the most useful for data scientists?

Python wasn’t built for data science. However, in recent years it has grown to become the go-to programming language for the following:

  • Machine learning
  • Predictive analytics
  • Simple data analytics
  • Statistics
    For data science projects, the following packages in the Python standard library will make life easier and accelerate deliveries:

NumPy (to process large multidimensional arrays, extensive collections of high-level mathematical functions, and matrices)
Pandas (to leverage built-in methods for rapidly combining, filtering, and grouping data)
SciPy (to extend NumPy’s capabilities and solve tasks related to integral calculus, linear algebra, and probability theory)
