Python - 计算一个列表中有多少个元素出现在 csv 行中

Question

I have a large list of many strings such as ':0001959' etc... I also have a file with many csv lines and some of these lines contain the strings I have in this list. What I need to do, is to count (for each line) how many elements from this list are matched to each line.

 split_string = line.split(",")
         for split_string in line:
             if split_string[0] in Lethality:
                  count = count +1

The above code is a quick look at what I already have. Thanks

You need to go through the elements in the split_string list which contains your csv splitted data, you are going to override split_string with the characters that are in the original csv line with this for loop, so you can modify your code as :

split_string = line.split(",")
for element in split_string:
    if element in Lethality:
        count = count + 1
