以下是Python实现词云的步骤和代码示例： 1.安装 wordcloud 库和 matplotlib 库 ```shell pip install wordcloud matplotlib ``` 2.导入所需库 ```python from wordcloud import WordCloud import matplotlib.pyplot as plt from PIL import Image import numpy as np ``` 3.准备文本和遮罩图片 ```python text = 'Python编程非常有趣，是一门易学难精的编程语言。' mask = np.array(Image.open('heart.jpg')) ``` 4.生成词云 ```python wc = WordCloud(background_color='white', mask=mask, contour_width=3, contour_color='steelblue') wc.generate(text) ``` 5.显示词云 ```python plt.imshow(wc, interpolation='bilinear') plt.axis("off") plt.show() ``` 6.保存词云 ```python wc.to_file('wordcloud.png') ``` 完整代码如下： ```python from wordcloud import WordCloud import matplotlib.pyplot as plt from PIL import Image import numpy as np text = 'Python编程非常有趣，是一门易学难精的编程语言。' mask = np.array(Image.open('heart.jpg')) wc = WordCloud(background_color='white', mask=mask, contour_width=3, contour_color='steelblue') wc.generate(text) plt.imshow(wc, interpolation='bilinear') plt.axis("off") plt.show() wc.to_file('wordcloud.png') ```
