第一种方法：
fo=open("sunstr.txt","r",encoding="utf-8")
sunstr=fo.read().lower()
for ch in ",.":sunstr.replace(ch," ")
sunstr = sunstr.split();
sunstrset = set(sunstr)dic = {}
for i in sunstrset:dic[i] = sunstr.count(i)
print(dic)for key in dic:print(key,dic[key]);wcList = list(dic.items())def tskeSecond(elem):return elem[1]wcList.sort(key=tskeSecond,reverse=True)
print(wcList)
第二种方法：
def getTxt():txt = open("sunstr.txt").read()txt = txt.lower()for ch in '!"@#$%^&*()+,-./:;<=>?@[\\]_`~{|}':txt.replace(ch," ")return txt
# sunstr = sunstr.replace(","," ")sunstr = getTxt().split()
sunstrset = set(sunstr)dic = {}
for i in sunstrset:dic[i] = sunstr.count(i)
print(dic)for key in dic:print(key,dic[key]);wcList = list(dic.items())def tskeSecond(elem):return elem[1]wcList.sort(key=tskeSecond,reverse=True)
print(wcList)
中文统计：
import jieba

word = list(word)
print(word)wordset =set(word)
