Python-如何计算字符串列表中部分字符串的出现次数

Question

如果我有一个清单，比如list = [abc都是字母，大象，香蕉是黄色，苹果是水果]或类似的东西，我怎么算这个单词＆＃39;的次数＆＃ 39;出现在这个列表中？

Answer 1

您不应该使用list作为变量名称，但这可以使用：

my_list = ["abc are all letters", "elephants", "bananas are yellow", "apples are fruits"]
count = 0
for string in my_list:
    if "are" in string:
       count += 1

Answer 2

los =  ["abc are all letters, elephants", "bananas are yellow, apples are fruits"]

sum((itm.count("are") for itm in los))
