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.

write
len()
^

2. Function to empty the contents of a file - no recovery is possible

4. asks the user for a response and returns that response
read
input()
file.truncate()

13. The keyword beginning a header that will create a new function.

len()
<
insert()

24. Create a variable.
open()
and
>=
=

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