in PYTHON

Write a function update() that converts the column in the database file "example.db" from a percent to a decimal. For instance, 98.7 percent in the original database file should be converted to the decimal 0.987.

Write another function high avg() that prints the average of all scores that are above 50%.

(use SQL commands to extract the average from the database file)
