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. Function to open or read a file
math.sqrt(a)
%r
open()
pass

2. Greater than or equal symbol.
%=
open()
>=
-=

3. writes stuff to the file
file.write(stuff)
>
argv
not in

4. Prints a string to the screen which is converted using repr()
a//b
%r
==
&

5. add AND assignment operator
file.write(stuff)
while
+=
round()

6. rounds a number to the number of decimal points you choose
not
<<
round()
argv

7. Prints a string to the screen which is a signed decimal.
or
%d
insert()
and

8. subtract AND assignment operator
-=
%r
elif (Else if)
in

9. Modulus operator. It's the remainder after division
math.sqrt(a)
%
read
return

10. This statement exits a function. The remaining lines of the function are not executed.
in
>>
return
def

11. Function to close a file - it will not be able to be used again unless the file is opened.
^
close
else
str()

12. Binary AND Operator copies a bit to the result if it exists in both operands. (a & b) will give 12 which is 0000 1100
break
&
-
close

13. This keyword attempts to do something that would cause the program to crash if it were not for this statement.
%s
/
%=
try

14. Holds the value of something - e.g. oh_hi = 4 where oh_hi is the variable.
**=
~
Variables

15. floor division
is
a//b
int()
=

16. Symbol to subtract things from each other
%r
not
-
int

17. End header line.
:
>
*
%d

18. 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.
~
break
abs(a)
argument variable

19. Binary Left Shift Operator. The left operands value is moved left by the number of bits specified by the right operand. a << 2 will give 240 which is 1111 0000
append()
~
<<
.py

20. A built-in function that converts integers and strings to floating-point numbers.

#
and

27. Greater than symbol
>
elif (Else if)
print()
