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. Function to write something to a file
write
print
len()
while

2. Create a variable.
=
str
else
.py

3. Function to empty the contents of a file - no recovery is possible
a**b
truncate
a//b

4. floor division
if
-
a//b
a%b

5. This keyword in the body of a conditional allows chained conditionals.
elif (Else if)
write
=
=

6. unction to read one line of a file
readline
if
argv
.py

7. modulo
/=
assignment
a%b
insert()

8. multiply AND assignment operator
()
*truncate
=
*=

9. returns the length of a string (number of characters)
-=
def
len()
argv

10. rounds a number to the number of decimal points you choose
write
float
round()
a//b

11. Symbol to divide by the number to the right of the symbol
/
math.sqrt(a)
<<
>>

12. Create a variable.
float
=
Variables
print

13. A logical operator which compares two operands and produces True if they are equal and False otherwise
<<
print()
==
in

14. A built-in function that converts integers and strings to floating-point numbers.
n
print()
float
//=

15. A logical operator which returns a value of True if either of the conditions is true.
/
or
else
int()

16. This statement causes an exception.
raise
*
len()
|

17. A statement that ends the current iteration of a loop but continues looping.
continue
.py
<<
&

18. Symbol to add things together
if
+
argv
not

19. absolute value
abs(a)
argv
#
%r

20. Adds something to a variable
**=
file.seek()
&
=

21. adds an item to a list
append()
a//b
>=
is

22. Symbol to subtract things from each other
and
-
%r
def

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

24. rounds a number to the number of decimal points you choose
~
*=
abs(a)
round()

25. Binary OR Operator copies a bit if it exists in eather operand. (a | b) will give 61 which is 0011 1101
%r
readline
is not
|

26. This keyword begins the simplest form of a conditional statement.
*readline
^
if
