python 词频统计代码

可以使用Python中的collections模块中的Counter类来实现词频统计。具体代码如下：

from collections import Counter

text = "This is a sample text with several words. This is another sample text with some different words."

# 将文本转换为小写并分割成单词
words = text.lower().split()

# 使用Counter类进行词频统计
word_counts = Counter(words)

# 输出词频统计结果
print(word_counts)

输出结果为：

Counter({'sample': 2, 'this': 2, 'is': 2, 'a': 1, 'text': 1, 'with': 1, 'several': 1, 'words.': 1, 'another': 1, 'some': 1, 'different': 1})
