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. Evaluates to true if it does not finds a variable in the specified sequence and false otherwise. x not in y - here not in results in a 1 if x is a member of sequence y.
<
not in
a%b
open()

2. Symbol used to create comments
truncate
#
*
elif (Else if)

3. Function to empty the contents of a file - no recovery is possible
%d
and
-=
truncate

4. deletes an item from a list
else
%=
()
del

5. multiply AND assignment operator
%=
print
//=
*=

6. add AND assignment operator
~
str()
+=
/

7. Command to print to the screen
del
else
print()
print

8. adds an item to a list
raise
try
append()
abs(a)

9. Create a variable.
a%b
+
=
|

10. returns the length of a string (number of characters)
.py
%d
len()
str()

11. floor division AND assignment operator
//=
print()
else
elif (Else if)

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

13. square root
if
math.sqrt(a)
is
readline

14. The extension for Python scripts
argv
*=
readline
.py

15. empties the file
%
file.truncate()
>
argv

16. Symbol to divide by the number to the right of the symbol
floating point number
/
==
round()

17. modulo
a%b
del
insert()
*read

18. Less than symbol
<
^
|
&

19. Command to print to the screen
/=
-=
print
int()

20. This keyword begins the simplest form of a conditional statement.
format string
~
~
if

21. Prints a string to the screen which is converted using repr()
n
del
len()
%r

22. Evaluates to false if the variables on either side of the operator point to the same object and true otherwise. x is not y - here is not results in 1 if id(x) is not equal to id(y).
is not
del
math.sqrt(a)
readline

23. End header line.
:
%d
print
append()

24. floor division
while
class
close
a//b

25. Prints a string to the screen which is a signed decimal.
%d
while
:
class

26. Adds a new line character
#
%
n
in

27. assignment operator
>
=
while
int()

28. A logical operator which negates an expression so that it returns a value of True if the expression is false.
not
readline
for
truncate

29. 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
()
append()
#
^

30. An operator that removes a value from a list.
del
argv
file.truncate()
for

31. Binary AND Operator copies a bit to the result if it exists in both operands. (a & b) will give 12 which is 0000 1100
&
=
int()
%=

32. Modulus operator. It's the remainder after division
>=
%
/=
==

33. The extension for Python scripts
=
input()
print()
.py

34. This keyword in the body of a conditional - gives an alternative execution.
close

else

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