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. writes stuff to the file
file.write(stuff)
%=
a**b
%=

2. Symbol used to create comments
file.write(stuff)
>>
#
=

3. rounds a number to the number of decimal points you choose
=
round()
try
readline

4. A built-in function that converts its argument to a string.
#
.py
read
str

5. End header line.
:
/
#
()

6. multiply AND assignment operator
*=
/
>
~

7. floor division
a//b
%
>
>>

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

9. Reads the contents of the file you can assign the result to a variable.
*read
//=
Variables
<<

10. assignment operator
break
pass

=

11. absolute value
#
format string
floating point number
abs(a)

12. Empties the file - watch out if you care about the file.
()
*truncate
len()
<<

13. An operator that removes a value from a list.
=
readline
a**b
del

14. Symbol to add things together
for
+
str()
-

15. Create a variable.
//=
def
+=
=

16. unction to read one line of a file
a%b
str()
math.sqrt(a)
readline

17. A statement that breaks out of a loop.
~
break
=
=

18. This keyword in the body of a conditional allows chained conditionals.
elif (Else if)
%
open()
assignment

19. Less than or equal to symbol
<=
+
-
elif (Else if)

20. square root
math.sqrt(a)
and
except
float

21. This keyword begins the simplest form of a conditional statement.
>=
=
round()
if

22. The extension for Python scripts
floating point number
read
open()
.py

23. divide AND assignment operator
if
len()
str()
/=

24. Less than symbol
+=
>>
a//b
<

25. This statement exits a function. The remaining lines of the function are not executed.
close
*=
return
a//b

26. This keyword begins a header for a body that repeats until the condition is no longer true.
<
del
for
while

27. inserts an item inside a list at a certain index
not in
/
print()
insert()

28. floor division AND assignment operator
//=
write
+
<

29. Symbol used to create comments
=
or
int()
#

30. Prints a string to the screen which is converted using repr()
%s
|
>
%r

31. Function to empty the contents of a file - no recovery is possible
>=
+=
truncate
~

32. Prevents a runtime error from stopping the program.
except
def
a**b
read

33. assignment operator
insert()
<
=
>

34. This keyword creates a new class object which is a user-defined type - like a factory for creating objects.
class
=
/=
#

35. Less than or equal to symbol
>>
<=
.py
continue

36. Adds something to a variable
#
*truncate
=
format string

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.
.py

%s
continue

38. A built-in function that converts integers and strings to floating-point numbers.
%
float
try
()

39. Function to write something to a file
a//b
%d
a%b
write

40. floor division AND assignment operator
+=
//=
&
class

41. divide AND assignment operator
read
write
/=
return

42. 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
while
except
in
>>

43. Symbol to multiply things
<
raise
str()
*

44. exponentiation
str()
=
~
a**b

45. 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).
>>
print()
is not
*=

46. Command to print to the screen
else
//=

round()
file.write(stuff)
argv
#

49. 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
