Exam Questions and Answers 2025
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
What does it mean to index a string? How do you do that with Python code? -Correct
Answer ✔This is what we call selecting a sub-sequence of a string. You do this in
Python by specifying the character you want to access by its index position. Index
position begins at 0. For example, this code would print out the letter J:
name = 'John'
print name[0]
What does it mean to slice a string? How do you do that with Python code? -Correct
Answer ✔Slicing is simply obtaining a subset of data from a string. You may have also
heard this called string extraction. You do this in Python by specifying the index position
where you want to begin and where you want to end. Everything from the starting point
up until the end point will be extracted. For example, this code would print out "Jo":
name = 'John'
print name[0:2]
+ -Correct Answer ✔concatenate or add
= -Correct Answer ✔assignment
* -Correct Answer ✔multiply
- -Correct Answer ✔subtract
/ -Correct Answer ✔divide
% -Correct Answer ✔Modulos, does division and returns the remainder
What does the * operator do when applied to string data? -Correct Answer ✔It writes out
the string data multiple times. For example, print '!' * 12 would output !!!!!!!!!!!! (12
exclamation points).
