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. 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.
**=
+=
a**b
not in

2. This keyword attempts to do something that would cause the program to crash if it were not for this statement.
>=
:
try
input()

3. Adds something to a variable
for
Variables
=
open()

4. adds an item to a list
append()
-
int()
def

5. Greater than symbol
len()
print
>
is not

6. Argument variable
#
round()
argv
=

7. Prints a string to the screen which is a signed decimal.
for
>>
%d
str

8. 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
.py
format string

9. Called Logical AND operator. If both the operands are true then then condition becomes true. (a and b) is true.
len()
%=
or
and

10. Function to write something to a file
=
write
a%b
round()

11. Command to print to the screen
Variables
is not
print
append()

12. turns an object into a string
break
str()
=
truncate

13. Prints a string to the screen which is converted using repr()
%r
=
def
%d

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

15. divide AND assignment operator
n
*
round()
/=

16. Function to empty the contents of a file - no recovery is possible
len()
for
round()
truncate

17. Reads the contents of the file you can assign the result to a variable.
*read
open()
assignment
%s

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

19. Empties the file - watch out if you care about the file.
:
*truncate
open()
write

20. Symbol to multiply things
*
>>
if
while

21. returns the length of a string (number of characters)
len()
del

open()

22. Symbol used to create comments
a%b
len()
len()
#

23. This keyword begins the simplest form of a conditional statement.
and
+=
if
=

24. The keyword beginning a header that will create a loop.
continue
argv
+
for

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

26. A statement that ends the current iteration of a loop but continues looping.
*
continue
<<
class

27. The keyword beginning a header that will create a new function.
str()
def
close
.py

28. Binary AND Operator copies a bit to the result if it exists in both operands. (a & b) will give 12 which is 0000 1100
<<
open()
#
&

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

30. floor division AND assignment operator
n
print()
//=
*

31. exponentiation
a**b
-

32. absolute value
=
**=
insert()
abs(a)

33. rounds a number to the number of decimal points you choose
-
+
in
round()

34. Function to open or read a file
open()
a**b
%r
truncate

35. Less than symbol
open()
&
<
/=

36. square root
float
math.sqrt(a)
write
truncate

37. A logical operator which returns a value of True if either of the conditions is true.
str()
or
for
~

38. Greater than or equal symbol.
abs(a)
==
#
>=

39. single line comment
#
and
read
==

40. 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
<<
