Python 簡介

Learning Environment: The course utilizes a blended classroom approach. The content is fully web-based, with
students writing and running code in the browser. Teachers utilize tools and resources provided by CodeHS to
leverage time in the classroom and give focused 1-on-1 attention to students. Each unit of the course is broken
down into lessons. Lessons consist of video tutorials, short quizzes, example programs to explore, and written
programming exercises, adding up to over 100 hours of hands-on programming practice in total. Each unit ends
with a comprehensive unit test that assesses the student’s mastery of the material from that unit.
Programming Environment: Students write and run Python programs in the browser

circles on the bottom row, 2 in the middle, and 1 on top.
○ Bubble Wrap 2.0
■ In this program, you should have Tracy add highlights to
each bubble from our Bubble Wrap example program. Use
top down design to break this large problem into smaller
pieces!
○ Rating
■ Write a program that shows a graphical representation of a
user’s rating value. If the value is between 1 and 4, draw a red
X. If it is between 5 and 7, draw a yellow horizontal line. If it is
