- The goal of this project is to be a concise guide for those transitioning from Python to Scala. This is by no means meant to be a complete guide to Scala, but rather some (hopefully) helpful snippets of code to help you translate between the two languages.
- This guide loosely follows along with the text of Scala for the Impatient, a great introductory book for those learning Scala. You might find it helpful to read it alongside the chapters from this repo.
- Note that in general, you should not try to directly translate idioms from one language to another; you don't want to write Scala that looks like Python- you want to write Scala that looks like Scala! You should strive to write idiomatic code whenever possible. A good starting point is Twitter's Effective Scala
- I recommend reading through the guide in the following order:
- 1.Variables and Arithmetic
- 2.Conditionals
- 3.Functions
- 4.Strings
- 5.Arrays
- 6.Maps
- 7.Tuples
- 8.Exceptions
- 9.Classes
- Here are some Scala topics not discussed above that I think are important to review:
- •Pattern Matching This is like a switch statement on turbo, and is very powerful and oft used. The Scala Cookbook has really great practical examples.
- •Auxiliary Constructors Classes can have multiple constructors that operate on different argument types/number of args.
- •Case Classes as an immutable, record-like data-structure that can be pattern-matched.
- •Scala Collections There is a lot of power in all of the methods available to data structures like Vector, Array, List, Sequence, Set, etc. Just take a look at all of the available methods.
- All of the code for this book can be found on Github.
