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. unction to read one line of a file
n
print
readline
float

2. exponentiation
>=
append()

a**b

3. Turns a line into a comment instead of executable code.
>>
&
truncate
#

4. 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
<<
append()
del
int()

5. Greater than symbol
>
==
math.sqrt(a)
>>

6. Function to write something to a file
a//b
a//b
write
def

7. Symbol to multiply things
print
<=
*
/=

8. A built-in function that takes any value and converts it to an integer if possible - or complains otherwise.
int
argv
%s
=

9. Prints a string to the screen which is converted using repr()
%r
%s
not in
read

10. turns an object into a string
floating point number
else
or
str()

11. End header line.
:
truncate
while
assignment

12. Command to print to the screen
floating point number
print
file.readline()
-

13. absolute value
and
while
abs(a)
^

14. reads just one line of a text file & keeps track of where in the file you're at
a%b
#
file.readline()
break

15. Empties the file - watch out if you care about the file.
<<
:
*truncate
^

16. floor division AND assignment operator
file.write(stuff)
//=
file.seek()
=

17. single line comment
#
.py
close
a//b

18. 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
print
//=

19. absolute value
assignment
%s
abs(a)
continue

20. asks the user for a response and returns that response
Variables
%s
=
input()

21. Command to print to the screen
a%b
print
argv
|

22. This keyword in the body of a conditional - gives an alternative execution.
*
*=
class
else

23. 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.
for
not in
insert()
if

24. A data type for representing numbers with fractional values.
:
floating point number
else
in

25. This statement exits a function. The remaining lines of the function are not executed.
>>
truncate
+
return

26. modulo
file.write(stuff)
<<
=
a%b

27. prints its parameter to the console
<=
print()
*read
for

28. turns an object into a string

pass
str()
^

29. turns an object into an integer
int()
break
else
is

30. The extension for Python scripts
n
*truncate
%r
.py

31. A logical operator which compares two operands and produces True if they are equal and False otherwise
int()
==
close
//=

32. 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.truncate()
print
*

33. modulo

&
=

35. Function to read the contents of a file
read
str()
-=
open()

36. 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.
