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
while
str()

2. A statement that assigns a value to a variable.
print
assignment
=
/=

3. add AND assignment operator
else
//=
+=
**=

4. Command to print to the screen
else
print
>
abs(a)

5. 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
^
except
elif (Else if)
:

6. Function to write something to a file
def
write
#
.py

7. Greater than symbol
=
|
is
>

8. A boolean operator that takes two strings and returns True if the first appears as a substring in the second.
in
if
def
round()

9. Function to write something to a file
a//b
del
not in
write

10. A statement that breaks out of a loop.
=
close
try
break

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

12. Adds a new line character
.py
^
is not
n

13. assignment operator
=
abs(a)
#
close

14. Function to close a file - it will not be able to be used again unless the file is opened.
%
def
close
print

15. Less than or equal to symbol
argv
<=
a//b
del

16. A statement that ends the current iteration of a loop but continues looping.
continue
argv
insert()
is

17. adds an item to a list
file.readline()
append()
del
def

18. Create a variable.
truncate
int()
=
%

19. sets the file's current position
for
argv
file.seek()
*

20. turns an object into a string
print()
else
str()
if

21. returns the length of a string (number of characters)
len()
%r
~
read

22. exponent AND assignment operator
**=
open()
is not
floating point number

23. multiply AND assignment operator
for
:
*=
&

24. 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
print()
print()
in

25. divide AND assignment operator
/=
n
print()
argv

26. This keyword begins the simplest form of a conditional statement.
if
^
+=
-=

27. Holds the value of something - e.g. oh_hi = 4 where oh_hi is the variable.
abs(a)
math.sqrt(a)
*truncate
Variables

28. exponentiation
>>
class
a**b
str()

29. This keyword in the body of a conditional allows chained conditionals.
continue
write
elif (Else if)
^

30. Symbol used to create comments
**=
pass
#
%s

31. This keyword begins a header for a body that repeats until the condition is no longer true.
print
while
#
math.sqrt(a)

32. Less than or equal to symbol
insert()
abs(a)
not
<=

33. Function to empty the contents of a file - no recovery is possible
.py
class
truncate
assignment

34. asks the user for a response and returns that response
>
float
format string
input()

35. Empties the file - watch out if you care about the file.
insert()
*truncate
def
^

36. The keyword beginning a header that will create a loop.
is
open()
for
-

37. reads just one line of a text file & keeps track of where in the file you're at
*=
file.readline()
%
a**b

38. Binary OR Operator copies a bit if it exists in eather operand. (a | b) will give 61 which is 0011 1101
=
|
file.write(stuff)
continue

39. Function to empty the contents of a file - no recovery is possible
a//b
str()
truncate
&

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
&
#
%r
or

41. empties the file
%
^
==
file.truncate()

42. assignment operator
#
=
print
else

43. End header line.
file.readline()
for

44. This keyword creates a new class object which is a user-defined type - like a factory for creating objects.
~
class
truncate
argv

45. add AND assignment operator
continue
>>
math.sqrt(a)
+=

46. 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.
~
while
argument variable
>

47. End header line.
+

50. 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
and
