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. modulo
a%b
()
except
>>

2. floor division AND assignment operator
/=
print
//=
argv

3. 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.
-=
~
floating point number
argument variable

4. Symbol used to create comments
print
#
Variables

5. Symbol used to create comments
open()
*
a//b
#

6. Function to open or read a file
close
=
open()
truncate

7. 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
str()
|
>>
=

8. adds an item to a list
**=
is
append()
try

9. square root
len()
del
n
math.sqrt(a)

10. sets the file's current position
=
<=
file.seek()
class

11. prints its parameter to the console
print()
and
or
del

12. Prints a string to the screen which is a signed decimal.
*read
math.sqrt(a)
class
%d

13. A statement that breaks out of a loop.
*
break
floating point number
open()

14. End header line.
%
//=
argument variable
:

15. Greater than or equal symbol.
=
>=
=
*readline

16. A boolean operator that takes two strings and returns True if the first appears as a substring in the second.
else
*=
append()
in

17. A built-in function that takes any value and converts it to an integer if possible - or complains otherwise.
in
int
-=
readline

18. 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
in
read
%d
>>

19. modulus AND assignment operator
int
a**b
math.sqrt(a)
%=

20. single line comment
#
a**b
a//b
%=

21. A logical operator which returns a value of True if either of the conditions is true.
*read
read
or
Variables

22. Function to close a file - it will not be able to be used again unless the file is opened.
close
=
<<
else

23. A statement that ends the current iteration of a loop but continues looping.
continue
<
==
read

24. A logical operator which negates an expression so that it returns a value of True if the expression is false.
~
not
.py
a%b

25. inserts an item inside a list at a certain index
insert()
**=
^
append()

26. 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
*truncate
a%b
#
^

27. prints its parameter to the console
*
>
print()
=

28. A statement that assigns a value to a variable.
+=
=
assignment
%s

29. 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).
len()
math.sqrt(a)
is not
abs(a)

30. Adds a new line character
~
//=
&
n

31. writes stuff to the file

continue
/=
del

36. The keyword beginning a header that will create a loop.
for
truncate
#

37. 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.
*truncate
argument variable
==
not in

38. Where the parameters go. A necessary punctuation after any function even if it's empty.

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

41. A keyword that does nothing but fill space to indicate code which will be written later.
