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()
len()
in
*

2. returns the length of a string (number of characters)
input()
**=
int()
len()

3. turns an object into an integer
#
int()
argv
>

4. Function to empty the contents of a file - no recovery is possible
>
print
-
truncate

5. 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
#
>>
<
a%b

6. Function to open or read a file
abs(a)
open()
math.sqrt(a)
==

7. Prints a string to the screen which will be Unicode.
abs(a)
argv
%s
file.write(stuff)

8. Function to close a file - it will not be able to be used again unless the file is opened.
~
close
%r
**=

9. sets the file's current position
file.seek()
a**b
print
a%b

10. Turns a line into a comment instead of executable code.
>
#
file.truncate()
if

11. A logical operator which compares two operands and produces True if they are equal and False otherwise
**=
abs(a)
==
=

12. An operator to check whether two variables refer to the same object.
>>
is
&
<

13. Command to print to the screen
continue
else
print
>=

14. adds an item to a list
append()
-
floating point number
try

15. Reads the contents of the file you can assign the result to a variable.
def
while
append()
*read

16. The keyword beginning a header that will create a new function.
+=
def
a//b
insert()

17. Called Logical AND operator. If both the operands are true then then condition becomes true. (a and b) is true.
and
//=
print

&
**=

19. Greater than or equal symbol.
>=

open()
~

21. absolute value
a**b

abs(a)
while

22. Argument variable
%=
argv

23. 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
print
file.truncate()
<<

24. multiply AND assignment operator
file.seek()
*=
open()
or

25. multiply AND assignment operator
