Python：使用nltk统计词频并绘制统计图

# -*- coding: utf-8 -*-
from nltk import FreqDist
from matplotlib import rcParams
# matplotlib 设置中文字体
rcParams["font.family"] = "STHeiti"
rcParams["font.size"] = 8
words = ["你好", "你好", "我好", "我还有"]
freq = FreqDist(words)
print(freq.most_common(1))  # [('你好', 2)]
print(freq.freq("你好"))     # 频率 0.5
print(freq["你好"])          # 次数 2
freq.tabulate()              # 频率分布表
freq.plot()                  # 频率分布图
