Installing Python 3.7 in Amazon Linux 2

This is a way to build Python 3.7 from source and temporarily install it in Amazon Linux 2 without overwriting the system Python and without interfering with the Python in amazon-linux-extras.

At the time of this writing, Amazon Linux 2 offers Python 2.7.14 and (through the extras) Python 3.6.2, but Python 3.7.0 was just released.

1. Start Amazon Linux 2 and sign in. (I recommend a c5.large instance.)

Thinking Like a Function

Part 1: What's a function?

As a software engineer, you probably think of a function as a unit of code that takes some arguments and returns some value, eg:

 function square(x) { 
   return x * x;
 }

This project is a tiny compiler for a very simple language consisting of boolean expression.

The language has two constants: 1 for true and 0 for false, and 4 logic gates: ! (not), & (and), | (or), and ^ (xor).

It can also use parentheses to manage priorities.

Here is its grammar in BNF format:

expr ::= "0" | "1"
