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. Symbol to divide by the number to the right of the symbol
#
/
file.seek()
-=

2. Adds something to a variable
=
print()
%=
>=

3. add AND assignment operator
+=
del
%s
a%b

4. exponentiation
/
str()
a**b
if

5. modulus AND assignment operator
%=
append()
readline
print

6. Function to empty the contents of a file - no recovery is possible
truncate
%r
a**b
:

7. Command to print to the screen
Variables
is
print
and

8. Function to write something to a file
write
file.seek()
=
in

9. Symbol to subtract things from each other
-
>
len()
or

10. rounds a number to the number of decimal points you choose
==
not
%d
round()

11. unction to read one line of a file
>=
readline

%d

12. Turns a line into a comment instead of executable code.
for
:
file.truncate()
#

13. returns the length of a string (number of characters)
*readline
len()
math.sqrt(a)
floating point number

14. subtract AND assignment operator
%r
except
argv
-=

15. 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
//=

16. turns an object into an integer
in
readline
int()
a%b

17. sets the file's current position
round()
//=
append()
file.seek()

18. subtract AND assignment operator
#
-=
%d
for

19. This keyword creates a new class object which is a user-defined type - like a factory for creating objects.
Variables
class
a%b

20. square root
math.sqrt(a)

21. Symbol to multiply things

math.sqrt(a)
&
=

23. Function to open or read a file
open()
+=
>
round()

24. Binary AND Operator copies a bit to the result if it exists in both operands. (a & b) will give 12 which is 0000 1100
&
not
**=
*

25. single line comment
#
read
~
format string

26. The keyword beginning a header that will create a loop.
#
print
is not
for

27. Adds a new line character
:
round()
n
>

28. divide AND assignment operator
=
%r
/=
del

29. prints its parameter to the console
+

math.sqrt(a)
print()

30. floor division

print

31. Create a variable.
=
%s
argv
read

32. Less than symbol
a//b

open()
<

33. Prints a string to the screen which is converted using repr()
%r
del
>>
format string

34. absolute value
abs(a)
%=
a%b
-

35. Prints a string to the screen which is a signed decimal.
truncate
%d
str()
>>

36. Function to open or read a file
open()
print
del
Variables

37. This keyword in the body of a conditional allows chained conditionals.
elif (Else if)
str()
input()

38. Where the parameters go. A necessary punctuation after any function even if it's empty.
*read
%s
()
>>

39. square root
%s
def
is
math.sqrt(a)

40. 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.
%r
#
not in
append()

41. Where the parameters go. A necessary punctuation after any function even if it's empty.
()
float
*read
write

42. A logical operator which compares two operands and produces True if they are equal and False otherwise
a**b
==
%d
print

43. multiply AND assignment operator
print
print()
*=
insert()

44. Reads the contents of the file you can assign the result to a variable.
*read
*truncate
<<
a**b

45. Evaluates to true if it finds a variable in the specified sequence and false otherwise. x in y - here in results in a 1 if x is a member of sequence y.
