mac python 文本分析 词云

以下是使用Python在Mac上进行文本分析并创建词云的步骤：

1. 安装必要的库

pip install wordcloud numpy pillow matplotlib

2. 创建一个简单的心形词云

from wordcloud import WordCloud
import matplotlib.pyplot as plt

text = "这是您要分析的文本内容"
# 生成词云
wordcloud = WordCloud(width=800, height=400, background_color='white', contour_color='steelblue').generate(text)

# 显示词云
plt.figure(figsize=(10,5))
plt.imshow(wordcloud, interpolation='bilinear')
plt.axis('off')
plt.show()

3. 创建一个自定义形状的词云

from wordcloud import WordCloud, ImageColorGenerator
from PIL import Image
import numpy as np

# 读取形状图片
mask = np.array(Image.open("heart_shape.png"))

# 生成词云
wordcloud = WordCloud(width=800, height=400, background_color='white', mask=mask, contour_color='steelblue').generate(text)

# 根据形状图片着色
image_colors = ImageColorGenerator(mask)
plt.figure(figsize=(10, 5))
plt.imshow(wordcloud.recolor(color_func=image_colors), interpolation="bilinear")
plt.axis('off')
plt.show()
