在Python中查找列表中所有单词的字符数

我试图找到单词列表中的字符总数，特别是这个列表：

words = ["alpha","omega","up","down","over","under","purple","red","blue","green"]

我尝试过这样做：

print "The size of the words in words[] is %d." % len(words)

但这只是告诉我列表中有多少个单词，即 10 个。

任何帮助，将不胜感激！

抱歉，我想说的是，我正在执行此操作的课程是关于 for 循环的主题，所以我想知道是否必须实现 forloop 才能给我答案，这就是 for 循环标签存在的原因。

您可以使用len列表理解中的函数，它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]

然后简单地sum使用生成器表达式

>>> sum(len(i) for i in words)
43

如果你真的一心一意for loops.

total = 0
for word in words:
    total += len(word)

>>> print total
43
