Python - 有多少只是列表中的一个单词

Question

如何获取列表中单个单词的总数。下面的列表中有 8 个元素。但是，有些元素中有多个单词 'apples are delicious'，如何只从列表中捕获单个单词的数量？

list = ['apples', 'apples', 'apples are delicious', 'oranges', 'fruits', 'kiwi', 'fruit festivals', 'festivals']

len(list) # total number of elements in a list
list.count("apples") # only counts a specific word but not a element single words

# total 8 elements 
# how many are only 1 word?
# results: 6/8 are 1 words

Answer 1

>>> lst = ['apples', 'apples', 'apples are delicious', 'oranges', 'fruits', 'kiwi', 'fruit festivals', 'festivals']
>>> len([w for w in lst if ' ' not in w])
6

顺便说一句，避免为变量命名 list，因为 list 是内置的
