使用聚合函数过滤输出

Question

I have a function that returns a list of strings that are being compared to one another and a score for each observation. I am trying to filter the output to scores that are greater than or equal to 80. When I applied the .filter it returned a list of true or false when I wanted a list of strings with a score of 80 or more.

#Assign your list1
Test_addrs = my_list1
#Assign your List2 and build the nested loop
target_addr = my_list2
for addr in Test_addrs:
    for target in target_addr:
        distance = string_match(target, addr, ratio_calc = True)
        #write results to a txt file
        mylist.append(f'{target}, {addr}, {distance}')

Answer 1

Use zip() with a list-comprehension:

strings_lst = ['a', 's', 'd', 'f', 'g']
scores_lst = [21, 24, 90, 54, 109]

print([x for x, y in zip(strings_lst, scores_lst) if y >= 80])
# ['d', 'g']
