What is an editor? ✔✔A program that allows you to write code

What is a compiler? ✔✔A program that produces other programs. The compiler does all the work

at once and then runs the new program. We're translating the code we wrote to computer code all

at once. This is often when we produce an .exe (executable) file.

What is an interpreter? ✔✔A program that runs code one line at a time. Instead of converting all

of the code at once it runs each line as it's needed. It interprets that specific line from your code to

computer code.

What is an operator and what does it do? ✔✔An operator takes two operands (values) and does

something with them. It is an object capable of manipulating a value. If it is a comparison or logical

operator it would compare to see if they are similar or dissimilar. If it is a mathematical operator

it would perform mathematical calculations.

What is an expression? ✔✔something that has a value.

What is the difference in a terminal and non-terminal expression? ✔✔A terminal is a final value,

while a non-terminal can be reduced further.

What is proper Python grammar for making an expression? ✔✔Expression → Expression

Operator Expression

The Expression non-terminal that appears on the left side can be replaced by an Expression,

followed by an Operator, followed by another Expression. For example, 1 + 1 is an Expression

Operator Expression.
