如何檢查單詞串列是否在字串中并且它們彼此靠近？[Python]

我有一個字串和一個單詞串列：

string ="""Ventilation box with reference VE03 with soundproofed box with inspection door
with the following technical characteristics: Air flow: 250 l s Available static pressure:
200 Pa With voltage regulator With characteristics according to project technical data
sheets Model make: CVB 4 180 180N or equivalent Includes flexible anti-vibration tarpaulins
at the air connections and metal dampers and supports Includes cable."""

list1 = ["CVB","1100","250"]
list2 = ["CVB","4","180","180N","RE","147W"]

我想檢查字串是否包含串列中的 2 個或更多單詞以及它們是否彼此靠近（例如前后 5 個位置/單詞）。使用“list1”必須為假，因為“CVB”和“250”不在一起，但使用“list2”應該回傳真（“CVB”、“4”、“180”和“180N”在一起）。

我的實際功能只檢測字串中是否有單詞：

count = 0
for word in list1: 
        if len(re.findall("(?<!\S)"   word   "(?!\S)", string)) > 0:
            count =1
print(count)

我的建議：

def my_function(my_string, list1):
    list_to_search_in = my_string.split()
    indices = []
    for word in list1:
        if word in list_to_search_in:
            indices.append(list_to_search_in.index(word))
    for index1 in indices:
        for index2 in indices:
            if abs(index1 - index2) <= 5:
                return True
    return False

還要檢查您的命名約定并避免使用string或list作為變數名之類的東西。

您可以考慮使用：collections.defaultdict

from collections import defaultdict
from itertools import combinations


def any_close_words(text: str, words: list[str], dist: int) -> bool:
    words = set(words)
    word_to_positions = defaultdict(list)
    for index, word in enumerate(text.split()):  # Could consider using a nltk tokenizer...
        if word in words:
            word_to_positions[word].append(index)
    for w1_positions, w2_positions in combinations(word_to_positions.values(), r=2):
        for a in w1_positions:
            for b in w2_positions:
                if abs(a - b) <= dist:
                    return True
    return False


def main() -> None:
    string = """Ventilation box with reference VE03 with soundproofed box with inspection door
with the following technical characteristics: Air flow: 250 l s Available static pressure:
200 Pa With voltage regulator With characteristics according to project technical data
sheets Model make: CVB 4 180 180N or equivalent Includes flexible anti-vibration tarpaulins
at the air connections and metal dampers and supports Includes cable."""
    print(f'{any_close_words(string, ["CVB", "1100", "250"], 5) = }')
    print(f'{any_close_words(string ["CVB", "4", "180", "180N", "RE", "147W"], 5) = }')


if __name__ == '__main__':
    main()

輸出：

any_close_words(string, ["CVB", "1100", "250"], 5) = False
any_close_words(string, ["CVB", "4", "180", "180N", "RE", "147W"], 5) = True

代碼：

def chk(string, lst):
    ls = string.split(' ')
    for i,s in enumerate(ls):
        if s in lst:
            if len(set([ls[i-1],s,ls[i 1]]).intersection (lst))>2:
                return True
    return False
chk(string, list2)
