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
-=
:
readline
file.readline()

2. Symbol to multiply things
>>
*
*=
str

3. A statement that ends the current iteration of a loop but continues looping.
continue
%
elif (Else if)
+

4. A logical operator which returns a value of True if either of the conditions is true.
or
append()
*truncate
*=

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

6. Function to write something to a file
try
Variables
print()
write

7. 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.
not in
*write(stuff)
is not
break

8. modulo
==
str
a%b
assignment

9. Function to read the contents of a file
-
for
%
read

10. Function to close a file - it will not be able to be used again unless the file is opened.
a**b
close
*read
input()

11. Adds something to a variable
=
<<
read
print

12. Symbol to add things together
+
math.sqrt(a)
append()
not in

13. This keyword in the body of a conditional allows chained conditionals.
str
int()
.py
elif (Else if)

14. This keyword begins the simplest form of a conditional statement.
int
assignment
close
if

15. turns an object into an integer
int()
a//b
>>
>>

16. Less than symbol
<
==
.py
&

17. Command to print to the screen
while
*=
readline
print

18. empties the file
()
a**b
-=
file.truncate()

19. Holds the value of something - e.g. oh_hi = 4 where oh_hi is the variable.
Variables
.py
.py
()

20. deletes an item from a list
del
print
-
#

21. 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
~
>>
math.sqrt(a)
=

22. returns the length of a string (number of characters)
file.seek()
str()
>>
len()

23. Reads the contents of the file you can assign the result to a variable.
/=
argv
*read
()

24. Function to open or read a file
or
open()
if
def

25. subtract AND assignment operator
-=
file.readline()
math.sqrt(a)
*write(stuff)

26. Symbol to subtract things from each other
-
%s
<<
for

27. Empties the file - watch out if you care about the file.
*truncate
not in
len()
if

28. Binary OR Operator copies a bit if it exists in eather operand. (a | b) will give 61 which is 0011 1101
for
try
=
|

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

30. Binary OR Operator copies a bit if it exists in eather operand. (a | b) will give 61 which is 0011 1101
read
.py
|
append()

31. Create a variable.
/=
~
&
=

32. unction to read one line of a file
readline
a%b
insert()
~

33. A keyword that does nothing but fill space to indicate code which will be written later.
pass
>=
=
elif (Else if)

34. Modulus operator. It's the remainder after division
argv
is
%
append()

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