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. A string that begins with the % symbol and contains a sequence of printable characters and format specifiers that determine how values output should look.
~
format string
#
/

2. A boolean operator that takes two strings and returns True if the first appears as a substring in the second.

Variables
%=
read

3. Greater than or equal symbol.
