在一定距离内查找句子中的2个字符串

def find_strings_in_distance(sentence, string1, string2, distance):
    words = sentence.split()  # 将句子拆分成单词列表

    index1 = -1
    index2 = -1

    for i in range(len(words)):
        if words[i] == string1:
            index1 = i
        elif words[i] == string2:
            index2 = i

    if index1 != -1 and index2 != -1 and abs(index1 - index2) <= distance:
        return True
    else:
        return False

# 示例用法
sentence = "This is a sample sentence to test the function."
string1 = "sample"
string2 = "function"
distance = 5

result = find_strings_in_distance(sentence, string1, string2, distance)
print(result)  # 输出：True
