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. Called Logical AND operator. If both the operands are true then then condition becomes true. (a and b) is true.
open()
%d
and
>>

2. unction to read one line of a file
truncate
readline
/=
n

3. modulus AND assignment operator
math.sqrt(a)
%=
insert()
#

4. prints its parameter to the console
readline
print()
*readline
=

5. absolute value
>
argument variable
*=
abs(a)

6. rounds a number to the number of decimal points you choose
.py
round()
class
if

7. Prints a string to the screen which will be Unicode.
%r
insert()
is
%s

8. Adds a new line character
<=
n
insert()
%=

9. The keyword beginning a header that will create a new function.
>>
insert()
math.sqrt(a)
def

10. The keyword beginning a header that will create a new function.
file.seek()
def
//=
=

11. Adds something to a variable
=
^
insert()
len()

12. divide AND assignment operator
def
/=
%s
+=

13. deletes an item from a list
~
if
*
del

14. turns an object into an integer
>>
int()
:
for

15. End header line.
>
()
:
*

16. assignment operator
*truncate
=
<
truncate

17. Binary XOR Operator copies the bit if it is set in one operand but not both. (a ^ b) will give 49 which is 0011 0001
>
file.truncate()
^
raise

18. add AND assignment operator
%
and
if
+=

19. This keyword in the body of a conditional - gives an alternative execution.
<<
%s
else
=

20. modulus AND assignment operator
int()
%=
math.sqrt(a)
class

21. A string that begins with the % symbol and contains a sequence of printable characters and format specifiers that determine how values output should look.
format string
insert()
file.truncate()
assignment

22. Symbol to multiply things
Variables
*
readline
^

23. Symbol to subtract things from each other
file.write(stuff)
*
-
round()

24. Binary Ones Complement Operator is unary and has the efect of 'flipping' bits. (~a ) will give -60 which is 1100 0011
close
truncate
~
Variables

25. asks the user for a response and returns that response
Variables
append()
assignment
input()

26. Turns a line into a comment instead of executable code.
%r
==
#
del

27. A keyword that does nothing but fill space to indicate code which will be written later.
class
or
pass
continue

28. Prevents a runtime error from stopping the program.
except
while
is
a**b

29. Reads just one line of a text file.
*readline
/
write
*

30. subtract AND assignment operator
not in
-=
/
except

31. Argument variable
**=
not
argv
in

32. subtract AND assignment operator
=
readline

-
not
|
<=

43. Greater than or equal symbol.
==
