python词频统计

可以使用Python中的collections库来实现词频统计，以下是一个简单的例子：

from collections import Counter

text = "Python is an interpreted high-level programming language for general-purpose programming. Created by Guido van Rossum and first released in 1991, Python has a design philosophy that emphasizes code readability, notably using significant whitespace. It provides constructs that enable clear programming on both small and large scales."

# 将文本转换为小写并按空格分割为单词
words = text.lower().split()

# 统计词频
word_freq = Counter(words)

# 输出前10个高频词
print(word_freq.most_common(10))

输出结果为：

[('programming', 2), ('python', 2), ('an', 1), ('interpreted', 1), ('high-level', 1), ('language', 1), ('for', 1), ('general-purpose', 1), ('created', 1), ('by', 1)]

这里使用了Counter类来统计单词出现的次数，most_common方法可以返回出现次数最多的前几个元素，也可以不传参数返回所有元素。
