如何将字符串拆分成字典，并将单词/句子从urls中分离出来，保持字符串的顺序

def split_string_to_dict(string):
    words = string.split()
    word_dict = {}
    for word in words:
        if word in word_dict:
            word_dict[word] += 1
        else:
            word_dict[word] = 1
    return word_dict

string = "Hello world hello"
result = split_string_to_dict(string)
print(result)

{'Hello': 1, 'world': 1, 'hello': 1}

import re

def extract_words_from_urls(urls):
    pattern = r'\b\w+\b'
    words = re.findall(pattern, urls)
    return words

urls = "https://www.example.com hello world https://www.example.com"
result = extract_words_from_urls(urls)
print(result)

['https', 'www', 'example', 'com', 'hello', 'world', 'https', 'www', 'example', 'com']
