篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了用Python来进行词频统计相关的知识,希望对你有一定的参考价值。

# 把语料中的单词全部抽取出来, 转成小写, 并且去除单词中间的特殊符号
def words(text): return re.findall([a-z]+, text.lower()) 
 
def train(features):
    model = collections.defaultdict(lambda: 1)
    for f in features:
        model[f] += 1
    return model
 
NWORDS = train(words(open(big.txt).read()))

读入的数据是:福尔摩斯探案,6mb这样......

输出NWORDS:
