Instructions:

Answer 50 questions in 15 minutes.
If you are not ready to take this test, you can study here.
Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

1. Argument variable
#
|
argv
%=

2. rounds a number to the number of decimal points you choose
*read
continue
round()
def

3. A logical operator which returns a value of True if either of the conditions is true.
append()
raise

or

4. single line comment

8. Prints a string to the screen which is a signed decimal.
%d
**=

a%b

9. ,multi-line comment hard-code,Fix (data or parameters) in a program in such a way that they cannot easily be altered by the user.

*read
/

~
for

12. floor division
a//b
=
argument variable
=

13. deletes an item from a list
~

pass
del

14. A built-in function that converts its argument to a string.
/
<=
str
math.sqrt(a)

15. turns an object into a string
#
=
&
str()

16. This variable holds the arguments you pass to your Python script when you run it. Then you unpack it in your script so you have variables you can work with.
