Learn Python The Hard Way学习(24) - 更多的练习
我们正从单纯的输入练习转移到学习代码的真正工作，我们需要做更多的练习。下面的练习比较长，考研你的耐心，下章的练习也一样。开始吧，保证你的输入正确。print "Let's practice everything."print 'You\'d need to know \'bout escapes with \\ that do \n newlines and \t tabs.'poem = """\tThe lovely worldwith logic so firmly plantedcannot discern \n the needs of lovenor comprehend passion from intuitionand requires an explanation\n\t\twhere there is none."""print "-----------"print poemprint "-----------"five = 10 - 2 + 3 - 6print "This should be five: %s" % fivedef secret_formula(started): jelly_beans = started * 500 jars = jelly_beans / 1000 crates = jars / 100 return jelly_beans, jars, cratesstart_point = 10000beans, jars, crates = secret_formula(start_point)print "With a starting point of: %d" % start_pointprint "We'd have %d beans, %d jars, and %d crates." % (beans, jars, crates)start_point = start_point / 10print "We can also do that this way:"print "We'd have %d beans, %d jars, and %d crates." % secret_formula(start_point)

运行结果Let's practice everything.You'd need to know 'bout escapes with \ that do  newlines and   tabs.-----------
The lovely worldwith logic so firmly plantedcannot discern  the needs of lovenor comprehend passion from intuitionand requires an explanation
where there is none.
-----------This should be five: 5With a starting point of: 10000We'd have 5000000 beans, 5000 jars, and 50 crates.We can also do that this way:We'd have 500000 beans, 500 jars, and 5 crates.
加分练习1. 反复阅读你的代码，朗读你的代码，给容易混淆的地方做注释。
2. 打乱你的文件，运行一下看报什么错误，解决这些错误。
