Day 2 of the PyGotham conference was on Saturday. I expected there to be way more people, but surprisingly, the opposite has happened. Day 2 count was twice as small, or at least that is how it felt. Below are the note from Day 2.

1000x faster data manipulation: vectorizing with Pandas and Numpy

Nathan Cheever @AdvancedMD Ds

For loop vs vectorization
Vectorization working with array or series without for loops, rather all at once.
- You are probably already doing that to some degree
To perform conditional vectorization do: numpy.where()
Numpy.vectorize()
Numpy.select() for multiple ifs / elifs
Pd.shift() to create anoer plumn with values shofted

Pull Requests: Merging good practices into your project

Luca Bezerra - vinta

Code review , even if unwanted adds greatly to the project
Best practices:
- Pull request template.md on github
- Status checks prevent branches merging without checks
- Contributing .md for collaboration
- Enforce approval/merge rules : codeowners.nd
- Using gitflow makes sure your branches are always up to dateCreated
- Using gitflow makes sure your branches are always up to dateCreated
  - Branches are cheap and great flexibility
- Keep pr size as small as possible
