The DRY or “Don’t Repeat Yourself” principle is a software development practice aimed at reducing repetition of information. In this lesson, you learned how to apply DRY when making comparisons in your Python code.

name = 'Mahdi' people_i_like = ['Mahdi', 'John', 'Linda'] if name in people_i_like: print 'yay!'
