Question

我试图制作一个简单的Web搜寻器，但是我的代码存在问题这是我在bucky robberts的youtube视频的帮助下完成的代码

import requests
from bs4 import BeautifulSoup
import operator


def start(url):
    word_list = []
    source_code = requests.get(url).text
    soup = BeautifulSoup(source_code, "html.parser")
    for text in soup.findAll("a", {"class": "result-title hdrlnk"}):
        content = text.string
        words = content.lower().split()
        for each_word in words:
            word_list.append(each_word)
    clean_up_list(word_list)


def clean_up_list(word_list):
    clean_word_list = []
    for word in word_list:
        symbols = "!@#$%^&*()_+-=[];',./\{}:\"<>?"
        for i in range(0, len(symbols)):
            word = word.replace(symbols[i], "")
        if len(word) > 0:
            clean_word_list.append(word)
    create_dictionary(clean_word_list)


def create_dictionary(clean_word_list):
    word_count = {}
    for word in clean_word_list:
        if word in word_count:
            word_count[word] += 1
        else:
            word_count[word_count] = 1
    for key, value in sorted(word_count.items(), key=operator.itemgetter(1)):
        print(key, value)


start("https://seattle.craigslist.org/search/jjj")

但是当我运行它时，我得到了这个错误

Traceback (most recent call last):
  File "C:/Users/Afsal/Desktop/python/learning/html.parser.py", line 40, in <module>
    start("https://seattle.craigslist.org/search/jjj")
  File "C:/Users/Afsal/Desktop/python/learning/html.parser.py", line 15, in start
    clean_up_list(word_list)
  File "C:/Users/Afsal/Desktop/python/learning/html.parser.py", line 26, in clean_up_list
    create_dictionary(clean_word_list)
  File "C:/Users/Afsal/Desktop/python/learning/html.parser.py", line 35, in create_dictionary
    word_count[word_count] = 1
TypeError: unhashable type: 'dict'

但是...我在评论部分找到了它，它是我尝试过的相同代码，并且效果很好

import requests
from bs4 import BeautifulSoup
import operator


def all_words(url,):
    word_list = []
    source_code = requests.get(url).text
    soup = BeautifulSoup(source_code, "html.parser")
    for before_text in soup.find_all("a", {"class": "result-title"}):
        content = before_text.string
        words = content.lower().split()
        for each_word in words:
            word_list.append(each_word)
    clean_up_list(word_list)


def clean_up_list(word_list):
    clean_word_list = []
    for word in word_list:
        symbols = "+\"*%&/()=?_-:.;,£$![]}{¦|@#¬~´"
        for i in range(0, len(symbols)):
            word = word.replace(symbols[i], "")
        if len(word) > 0:
            clean_word_list.append(word)
    create_dictionary(clean_word_list)


def create_dictionary(clean_word_list):
    word_count = {}
    for word in clean_word_list:
        if word in word_count:
            word_count[word] += 1
        else:
            word_count[word] = 1
    for key, value in sorted(word_count.items(), key=operator.itemgetter(1)):
        print(key, value)


all_words("https://cnj.craigslist.org/search/sys")

我不明白我的代码有什么问题，有人可以请他解释出什么问题吗，即时通讯使用python 3.7和pycharm

当我运行此代码时，TypeError：不可哈希类型：'dict'
