Exercise-03

Abstract

 ● Review the contents of the two courses on the main page of the cours master the grammar rules of Python and Matplotlib, and prepare for the next course.
 ● Moving your English name horizontally on the screen.
 ● Use the character to spell out what you want to draw on the 80*80 dot matrix, and let it spin, hoping to open the hole in the brain!

Background

  ● Using python preliminarily.
  ● Learning how to use matplotlib.
  ● Master the basic knowledge of computer program.

Conclusion

● This exercise is much more difficult than last one,but also much more interesting.
●  After this exercise,I can use python a little more adroitly,and I've learnt more grammar about python.
● Matplotlib is really useful in physics studing.
● Still unable to use Python and Matplotlib Skillfully.
