What to Focus On

  • NumPy stands for Numerical Python.
  • Pandas stands for PANelData.
  • Matplotlib is a plotting and visualisation library.

  • A data structure helps store, retrieve, and modify data efficiently.
  • Pandas has three important data structures: Series, DataFrame, and Panel.
  • Series is one-dimensional.

  • Series is a one-dimensional Pandas data structure.
  • Each Series value has an index label.
  • Default index values run from 0 to N-1.

Common Mistakes to Avoid

A DataFrame is just a bigger Series, so both behave the same way.

Series and NumPy arrays use the same indexing rules, so slicing works the same in both.

If a row label passed to DataFrame.loc[] is an integer, it is always treated as a row position.

Memory Tips

NumPy, Pandas, and Matplotlib as core Python libraries for scientific and analytical work

Pandas stands for PANelData and is a high-level data manipulation library

Series is a one-dimensional Pandas data structure with an index

DataFrame is a two-dimensional labelled data structure like a table
