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.

=
close
argv
class

2. A string that begins with the % symbol and contains a sequence of printable characters and format specifiers that determine how values output should look.
argv
format string
str()
a**b

3. This keyword creates a new class object which is a user-defined type - like a factory for creating objects.
append()
file.write(stuff)
|
class

4. Writes stuff to the file.
a//b
*write(stuff)
int()
def

5. prints its parameter to the console
print()
print
readline
input()

6. Function to empty the contents of a file - no recovery is possible
%d
read
truncate
*

7. returns the length of a string (number of characters)
pass
len()
int()
**=

8. returns the length of a string (number of characters)
len()
file.readline()
=
in

9. This keyword begins the simplest form of a conditional statement.
