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. Prevents a runtime error from stopping the program.
except
&
math.sqrt(a)
<=

2. sets the file's current position
=
read
else
file.seek()

3. A statement that assigns a value to a variable.
file.readline()
assignment
*=
#

4. multiply AND assignment operator
continue
format string
==
*=

5. A string that begins with the % symbol and contains a sequence of printable characters and format specifiers that determine how values output should look.
del
format string
+=
%r

6. Symbol to multiply things
read
is
*
*truncate

7. multiply AND assignment operator
-
()
%=
*=

8. Symbol used to create comments
#
input()
>=
-=

9. Function to open or read a file
round()
abs(a)
open()
def

10. A built-in function that takes any value and converts it to an integer if possible - or complains otherwise.
int
len()
<=
else

11. A logical operator which compares two operands and produces True if they are equal and False otherwise
readline
int()
append()
==

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

13. The keyword beginning a header that will create a new function.
int()
int()
in
def

14. This keyword in the body of a conditional - gives an alternative execution.
else
append()
return
format string

15. modulo
a%b
insert()
in
>>

16. Writes stuff to the file.
print
*write(stuff)
print
/=

17. A data type for representing numbers with fractional values.
floating point number
def
a**b
print

18. turns an object into a string
*
str()
a//b
+=

19. turns an object into a string
//=
str()
%d
-=

20. Function to empty the contents of a file - no recovery is possible
print
*write(stuff)
truncate
>>

21. Adds a new line character
n
round()
is not
class

22. Turns a line into a comment instead of executable code.
file.truncate()
#
and
round()

23. add AND assignment operator
+=
del
<<
insert()

24. This keyword in the body of a conditional allows chained conditionals.
write
=
elif (Else if)
def

25. Function to read the contents of a file
**=
%s
read
insert()

26. Where the parameters go. A necessary punctuation after any function even if it's empty.
and
abs(a)
int
()

27. The keyword beginning a header that will create a new function.
-=
read
str()
def

28. writes stuff to the file
math.sqrt(a)
file.write(stuff)
%r
+

29. 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
>>
#
-=
insert()

30. divide AND assignment operator
del
argument variable
readline
/=

31. Less than symbol
input()
//=
<
-=

32. This keyword begins a header for a body that repeats until the condition is no longer true.
>>
append()

while

33. Modulus operator. It's the remainder after division
int
math.sqrt(a)
%
>=

34. Function to close a file - it will not be able to be used again unless the file is opened.
-=
close
&
input()

35. Binary OR Operator copies a bit if it exists in eather operand. (a | b) will give 61 which is 0011 1101
/
|
>
=

36. exponent AND assignment operator
a**b
**=
input()
*

37. Command to print to the screen
%=
%
a**b
print

38. Function to empty the contents of a file - no recovery is possible
not in
truncate
>=
print()

39. An operator to check whether two variables refer to the same object.
<<
=
argv
is

40. exponent AND assignment operator
%d
*=
len()
**=

41. returns the length of a string (number of characters)
*truncate
:
>>
len()

42. subtract AND assignment operator
()
readline
-=
argv

43. Reads the contents of the file you can assign the result to a variable.
input()
=
*read
else

44. Binary Left Shift Operator. The left operands value is moved left by the number of bits specified by the right operand. a << 2 will give 240 which is 1111 0000
==
<<
&
>=

45. Where the parameters go. A necessary punctuation after any function even if it's empty.
len()
>>
*=
()

46. Adds something to a variable
file.seek()
*=
file.truncate()
=

47. This keyword begins the simplest form of a conditional statement.
floating point number
=
==
if

48. floor division
Variables
a//b
//=
*readline

49. Adds something to a variable
*truncate
=
%=
elif (Else if)

50. 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.
