from wordcloud import WordCloud  
import matplotlib.pyplot as plt  
from collections import Counter

import re  # 停用词列表，这里只是示例，你可以根据需要添加或修改  
stopwords = ['的', '是', '在', '了', '有', '和', '人', '我', '他', '她', '它', '们', '...','0','1','2','3','4','5','6','7','8','9','10','12','20','30']  # 读取Excel文件

wordcloud = WordCloud(font_path='simhei.ttf',  # 设置字体文件，确保能正确显示中文  background_color='white',  stopwords=None,  # WordCloud已经通过上面的步骤去除了停用词  min_font_size=10).generate_from_frequencies(word_freq)  plt.figure(figsize=(10, 10))
