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

2. A built-in function that takes any value and converts it to an integer if possible - or complains otherwise.
%r
*
int
len()

3. modulus AND assignment operator
a%b
%=
class
file.write(stuff)

4. This keyword in the body of a conditional - gives an alternative execution.
=
del
pass
else

5. Argument variable
//=
except
argv
a//b

6. single line comment
%=
+
<=
#

7. empties the file
readline
file.truncate()
if
%r

8. Symbol to divide by the number to the right of the symbol
%s
/
in
<=

9. Symbol to add things together
+
file.truncate()
=
/

10. Empties the file - watch out if you care about the file.
%d
%
*truncate
#

11. Adds something to a variable
del
=
str()
*readline

12. turns an object into an integer
+=
len()
is
int()

13. Binary AND Operator copies a bit to the result if it exists in both operands. (a & b) will give 12 which is 0000 1100
print
%
&
for

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

append()
Variables
~

15. exponent AND assignment operator
%
=
**=
insert()

16. modulus AND assignment operator
abs(a)
def
Variables
%=

17. multiply AND assignment operator
print
for
*=
break

18. rounds a number to the number of decimal points you choose
.py
round()
str()
else

19. Less than symbol
<
*readline
Variables
=

20. A keyword that does nothing but fill space to indicate code which will be written later.
*write(stuff)
is not
**=
pass

21. Where the parameters go. A necessary punctuation after any function even if it's empty.
%r
in
del
()

22. Less than or equal to symbol
=
<=
is not
def

23. 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.
/
>=
int()
argument variable

24. Holds the value of something - e.g. oh_hi = 4 where oh_hi is the variable.
append()
%s
+
Variables

25. A string that begins with the % symbol and contains a sequence of printable characters and format specifiers that determine how values output should look.
%r
n
format string
str()

26. A logical operator which returns a value of True if either of the conditions is true.
or
==
/=
abs(a)

27. inserts an item inside a list at a certain index
insert()
elif (Else if)
truncate
&

28. 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
<<
file.write(stuff)
/
round()

29. A statement that displays a value on the screen.
<
print
**=
//=

30. sets the file's current position
==
+
<<
file.seek()

31. This statement exits a function. The remaining lines of the function are not executed.
except
.py
return
close

32. A data type for representing numbers with fractional values.
insert()
floating point number
and
.py

33. This keyword begins a header for a body that repeats until the condition is no longer true.
Variables
//=
while
*readline

34. 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
read
.py
+=

35. rounds a number to the number of decimal points you choose
**=
round()
-
*=

36. absolute value
-
<<
abs(a)
print()

37. Less than symbol
<
def
~
%=

38. floor division AND assignment operator
insert()
//=
-
not in

39. This keyword begins the simplest form of a conditional statement.
argv
a**b
except
if

40. exponentiation
insert()
format string
raise
a**b

41. 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
close
a//b
%s
<<

42. 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.
