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
