What is an editor? - correct answer ✔✔A program that allows you to write code
What is a compiler? - correct answer ✔✔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? - correct answer ✔✔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? - correct answer ✔✔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? - correct answer ✔✔something that has a value.
What is the difference in a terminal and non-terminal expression? - correct answer ✔✔A
terminal is a final value, while a non-terminal can be reduced further.
What is proper Python grammar for making an expression? - correct answer ✔✔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.
What is a variable? - correct answer ✔✔a name that refers to a value
What are the three main types of data covered? How do you declare each one? - correct answer
✔✔string is a sequence of characters surrounded by quotes, either single or double
example: myVar = "string data"
Integer is a number - correct answer ✔✔example: myVar = 33
Boolean is a true or false value - correct answer ✔✔example: myVar = True
What is grammar used for in programming? - correct answer ✔✔In a programming language
like Python, the code must match the language grammar exactly. When programming language
grammar is not followed the interpreter will return a Syntax Error message. This means that the
structure of the code is inconsistent with the rules of the programming language.
How do you change the value of a variable with Python? - correct answer ✔✔Using the =
character to assign a new value
x=6
x=9
print x # would print out 9
How to do you join multiple variables together with string data in Python? What is this called? -
correct answer ✔✔Using the + sign to concatenate the values
