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. This statement causes an exception.
a//b

raise
~

2. Argument variable
~
a**b
argv
insert()

3. A built-in function that converts its argument to a string.
is not
+
str
^

4. assignment operator
=
try
in
math.sqrt(a)

5. sets the file's current position
Variables
file.seek()
abs(a)
==

6. modulo
>
*
a%b
//=

7. Where the parameters go. A necessary punctuation after any function even if it's empty.
round()
()
+=
**=

8. Prints a string to the screen which is converted using repr()
**=
%r
<
>>

9. 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
//=
<
<<
math.sqrt(a)

10. Less than symbol
<
-=
=
n

11. Symbol used to create comments
.py
n
if
#

12. Modulus operator. It's the remainder after division
n
append()
%
>=

13. Binary Ones Complement Operator is unary and has the efect of 'flipping' bits. (~a ) will give -60 which is 1100 0011
%r
~
%
else

14. A statement that displays a value on the screen.
print
file.truncate()
float

15. deletes an item from a list
-
del
or
%d

16. Function to write something to a file
.py
write
read
%d

17. Function to close a file - it will not be able to be used again unless the file is opened.
close
raise
<<
truncate

18. Reads the contents of the file you can assign the result to a variable.
+
file.truncate()
*read
*=

19. This keyword in the body of a conditional - gives an alternative execution.
str()

else
del

20. The extension for Python scripts
.py

del

21. exponent AND assignment operator
def
abs(a)
//=
**=

22. inserts an item inside a list at a certain index

insert()
n
raise

23. Greater than symbol
~
&
else
>

24. Adds something to a variable
.py

print
math.sqrt(a)
<=
def

29. The keyword beginning a header that will create a loop.
%s
for
class
a//b

30. 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.
