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. A data type for representing numbers with fractional values.
except
floating point number
*=
not

2. This keyword in the body of a conditional - gives an alternative execution.
<=
else
*=
>>

3. The keyword beginning a header that will create a new function.

def
continue
while

4. Binary Right Shift Operator. The left operands value is moved right by the number of bits specified by the right operand. a >> 2 will give 15 which is 0000 1111
file.truncate()
>>
+
raise

5. Function to empty the contents of a file - no recovery is possible
=
^
truncate
=

6. Prints a string to the screen which is converted using repr()
%
==
%r
del

7. Prints a string to the screen which is converted using repr()
n
%r
int()
append()

8. End header line.
a//b
~
a**b
:

9. 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).
a**b
=
is not
float

10. Turns a line into a comment instead of executable code.
|
:
insert()
#

11. 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.
-
argument variable
and
close

12. A logical operator which negates an expression so that it returns a value of True if the expression is false.
#
not
file.seek()
round()

13. Function to write something to a file
write
and
>>
len()

14. Modulus operator. It's the remainder after division
del
%
*write(stuff)
append()

15. subtract AND assignment operator
-=
while
%d
+

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

17. deletes an item from a list
insert()
def
del
argument variable

18. Greater than or equal symbol.
>=
/
n
^

19. deletes an item from a list
del
def
input()
>

20. 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
/=
^
a%b
not

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

22. This keyword begins the simplest form of a conditional statement.
*write(stuff)
argv
str
if

23. prints its parameter to the console
close
/
=
print()

24. absolute value
abs(a)
a%b
+

25. Prevents a runtime error from stopping the program.
except
*=
:
=

26. asks the user for a response and returns that response
len()
input()
for
argv

27. Less than symbol
not
assignment
argv
<

28. floor division AND assignment operator
//=
read
#
*read

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

30. This keyword begins the simplest form of a conditional statement.
#
if
n
^

31. Greater than or equal symbol.
>
format string
<<
>=

32. Function to read the contents of a file
read
~
round()
float

33. Called Logical AND operator. If both the operands are true then then condition becomes true. (a and b) is true.
and
input()
-=
insert()

34. A logical operator which returns a value of True if either of the conditions is true.
>
close
or
len()

35. An operator that removes a value from a list.
close
a**b
n
del

36. subtract AND assignment operator

37. Command to print to the screen
truncate
print
and
a//b

38. Symbol to multiply things

39. Function to close a file - it will not be able to be used again unless the file is opened.
close
%d
pass
read

40. Prints a string to the screen which is a signed decimal.
>
Variables
%d
<<

41. A logical operator which requires two expressions to both be true.
%
