您可以
len在列表推导中使用该函数，这将创建一个长度列表
>>> words = ["alpha","omega","up","down","over","under","purple","red","blue","green"]>>> [len(i) for i in words][5, 5, 2, 4, 4, 5, 6, 3, 4, 5]
然后只需
sum使用生成器表达式
>>> sum(len(i) for i in words)43
如果您真的有心动的话
for。
total = 0for word in words: total += len(word)>>> print total43
