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. assignment operator
**=
>>
==
=

2. Prevents a runtime error from stopping the program.
except
insert()
elif (Else if)
/

3. A built-in function that takes any value and converts it to an integer if possible - or complains otherwise.
elif (Else if)
<<
a**b
int

4. Where the parameters go. A necessary punctuation after any function even if it's empty.
for
and
()
//=

5. A keyword that does nothing but fill space to indicate code which will be written later.
pass
file.seek()
%=
print()

6. This keyword in the body of a conditional - gives an alternative execution.
*write(stuff)
else
read
round()

7. turns an object into an integer
not in
<<
int()
floating point number

8. The keyword beginning a header that will create a loop.
while
+=
for
:

9. writes stuff to the file
|
file.write(stuff)
*read
readline

10. Less than or equal to symbol
input()
else
<=
&

11. The keyword beginning a header that will create a new function.
/=
==
%=
def

12. Function to close a file - it will not be able to be used again unless the file is opened.
>=
print()
class
close

13. Binary Ones Complement Operator is unary and has the efect of 'flipping' bits. (~a ) will give -60 which is 1100 0011
=
~
+=
#

14. The keyword beginning a header that will create a new function.
~
print
>=
def

15. floor division AND assignment operator
a**b
*=
>
//=

16. 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
write
>>
float
pass

17. Function to read the contents of a file
<=
-
read
#

18. single line comment
#
//=
()

19. Modulus operator. It's the remainder after division
for
del
%d
%

20. Empties the file - watch out if you care about the file.
*read
*truncate
a**b
del

21. square root
>=
else
readline
math.sqrt(a)

22. Greater than symbol
<=
print
>
insert()

23. Adds something to a variable
print
&
=
>>

24. Command to print to the screen
print
>
read
not

25. Symbol to divide by the number to the right of the symbol
=
:
return
/

26. exponent AND assignment operator
math.sqrt(a)
not
**=
truncate

27. exponentiation
close
**=
a**b
Variables

28. adds an item to a list
print
append()
<
len()

29. Adds a new line character
/
<=
n
except

30. modulo
=
.py
a%b
<

31. Function to empty the contents of a file - no recovery is possible
a**b
del
print
truncate

32. sets the file's current position
print()
/=
file.seek()
print

33. unction to read one line of a file
==
readline
not
def

34. 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.
in
write
=
>=

35. Command to print to the screen
print
==
#
:

36. Turns a line into a comment instead of executable code.
#
a//b
%s
=

37. modulus AND assignment operator
len()
argv
~
%=

38. 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.
>>
/=
argument variable
int()

39. 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.
floating point number
str()
not in
+=

40. A string that begins with the % symbol and contains a sequence of printable characters and format specifiers that determine how values output should look.
>>
*read
format string
=

41. Function to open or read a file
except
-
open()
input()

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

43. 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
<<
insert()
read
open()

44. reads just one line of a text file & keeps track of where in the file you're at
