Which one of the following refers to the rules of a programming language that a
programmer must follow when developing software in that language? - Answers -
syntax
Python is a high-level language. - Answers - True
Which of the following is one of the reasons that Python is a popular language with

other languages.
A fictional country has 3 denominations of money: gold, silver and copper coins.
1 gold coin = 20 silver coins
1 silver coin = 4 copper coins
Given a total number of copper coins (given in the variable copper), we want the
computer to tell us how many gold coins (gold), silver coins (silver) and copper coins
(copper) are needed to make change while minimizing the number of coins.
Incomplete code is given below. Choose the option below that correctly completes the
code segments marked A and B.
, copper = 1000 # or any other positive integer
gold = copper // A
copper = copper % A
silver = copper // B
copper = copper % B - Answers - Replace A with 80, replace B with 4
What is the value of the following Python expression?
2 == 9
- 0.2222...
- This is an error
-2
- True
- None of these - Answers - None of these
Which of the following is the operator we use in Python to compute a total
incrementally? - Answers - +=
Which of the following would compute 5% of x and store that value in the variable y?
- y = 5% x
- y = x.5%
- y = 5% of x
- y = 5% * x
- None of these is correct - Answers - None of these is correct
Which of the following, if any, is NOT a valid Python variable name?
- HACKERS
- g33333
- if
- underscores____
- All of these are valid variable names - Answers - if
Select ALL of the expressions below that evaluate to the integer 1.
-5%3
-3%5
- 5 // 3
-3/5
- - Answers - 5 // 3
Select ALL of the values for x so that 5 - x equals x % 5.
