今天爱分享给大家带来 python3 统计一个list的词频【附代码】,希望能帮助到大家。
做统计机器学习经常需要统计,这里我来分享一下怎样统计一个list里面每个字符串的频率:
from collections import Counter word_count=['I','am','from','China',',','I','Love','my','country','!','!','!'] counter = Counter(word_count) dictionary=dict(counter) # get to k most frequently occuring words k=10 res=counter.most_common(k) print(res)
输出为:
[('!', 3), ('I', 2), ('am', 1), ('from', 1), ('China', 1), (',', 1), ('Love', 1), ('my', 1), ('country', 1)]
