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. The extension for Python scripts
=
>
.py
%r

2. Greater than or equal symbol.
open()
print

>=

3. Prevents a runtime error from stopping the program.
%=
except
>=
**=

4. square root
-
if
:
math.sqrt(a)

5. A logical operator which requires two expressions to both be true.
write
and
file.readline()
len()

6. The keyword beginning a header that will create a new function.
print()
def
/
Variables

7. Binary AND Operator copies a bit to the result if it exists in both operands. (a & b) will give 12 which is 0000 1100
if
:
readline
&

8. Greater than or equal symbol.
<<
>=
format string
-

9. Function to open or read a file
insert()
del
open()
class

10. This keyword begins a header for a body that repeats until the condition is no longer true.
print
.py
raise
while

11. A keyword that does nothing but fill space to indicate code which will be written later.
.py
not
pass
>=

12. add AND assignment operator
>=
//=
else
+=

13. A logical operator which negates an expression so that it returns a value of True if the expression is false.
round()
<
not
*read

14. 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
<<
%s
argv
readline

15. 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.
str()
len()
n
argument variable

16. Empties the file - watch out if you care about the file.
<=
in
*truncate
try

17. End header line.
:
=
and
>>

18. 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
^
+=

19. empties the file
print
is
file.truncate()
int()

20. modulus AND assignment operator
#
del
%=
in

21. subtract AND assignment operator
-=
*readline
for
readline

22. Prints a string to the screen which will be Unicode.
class
not in
%s
==

23. Writes stuff to the file.
.py
len()
%d
*write(stuff)

24. Create a variable.
=
str
**=
print

25. Symbol to subtract things from each other
round()
a**b
%
-

26. Greater than symbol
math.sqrt(a)
.py
a**b
>

27. Symbol to subtract things from each other
%=
=
is
-

28. Symbol to add things together
del
len()
+
and

29. returns the length of a string (number of characters)
len()
a//b
/=
>

30. This statement causes an exception.
a//b
continue
close
raise

31. Reads the contents of the file you can assign the result to a variable.
^
^
*read
:

32. rounds a number to the number of decimal points you choose
#
argv
read
round()

33. An operator to check whether two variables refer to the same object.
is
a//b
:
math.sqrt(a)

34. This keyword begins the simplest form of a conditional statement.
is
*read
>>
if

35. Command to print to the screen
print
~
+=
return

36. Symbol to divide by the number to the right of the symbol
/
:
#
else

37. ,multi-line comment hard-code,Fix (data or parameters) in a program in such a way that they cannot easily be altered by the user.
close
+=

not

38. A logical operator which returns a value of True if either of the conditions is true.
or
>=
print()
is

39. This keyword begins the simplest form of a conditional statement.
//=
if
argv
+

40. modulo
%r
>
a%b
*truncate

41. A logical operator which compares two operands and produces True if they are equal and False otherwise
def
str()
==
=

42. Called Logical AND operator. If both the operands are true then then condition becomes true. (a and b) is true.
and
>
readline
/=

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

44. Prints a string to the screen which is converted using repr()
|
%r
not in
>

45. A built-in function that converts integers and strings to floating-point numbers.
%s
abs(a)
float
write

46. deletes an item from a list
and
del
>=
a//b

47. Holds the value of something - e.g. oh_hi = 4 where oh_hi is the variable.
+
%=
*
Variables

48. Function to read the contents of a file
abs(a)
read
not in
file.seek()

49. A data type for representing numbers with fractional values.
math.sqrt(a)
:
