python数据预处理，词频分析，并生成词云图代码

您好，以下是 Python 数据预处理、词频分析并生成词云图的代码：

import jieba
from wordcloud import WordCloud
import matplotlib.pyplot as plt

# 读取文本文件
with open('text.txt', 'r', encoding='utf-8') as f:
    text = f.read()

# 使用 jieba 分词
words = jieba.cut(text)

# 统计词频
word_counts = {}
for word in words:
    if len(word) == 1:  # 排除单个字符的词
        continue
    word_counts[word] = word_counts.get(word, ) + 1

# 生成词云图
wordcloud = WordCloud(font_path='simhei.ttf', width=800, height=600, background_color='white')
wordcloud.generate_from_frequencies(word_counts)
plt.imshow(wordcloud, interpolation='bilinear')
plt.axis('off')
plt.show()

希望能对您有所帮助。
