帮我写一个python代码用来批量去除词云里面停用词

代码如下：

# 导入需要的库
import matplotlib.pyplot as plt
from wordcloud import WordCloud

# 定义停用词列表
stopwords = ['a', 'the', 'to', 'on', 'in', 'for', 'of', 'and', 'with', 'at']

# 定义词云
wordcloud = WordCloud()

# 去除停用词
wordcloud.stopwords = stopwords

# 生成词云
wordcloud.generate_from_text('请输入你要分析的文本')

# 显示词云
plt.imshow(wordcloud)
plt.axis('off')
plt.show()
