python用字典统计单词或汉字词个数示例
有如下格式的文本文件
/“/请/!/”/“/请/!/”/两名/剑士/各自/倒转/剑尖/,/右手/握/剑柄/,
/左手/搭于/右手/手背/,/躬身行礼/。/两/人/身子/尚未/站/直/,
/突然/间/白光闪/动/,/跟着/铮的/一/声响/,
/双剑相/交/,/两/人/各/退一步/。
/旁/观众/人/都/是/“/咦/”/的/一声/轻呼/。/青衣/剑士/连/劈/三/剑/
将这段话进行词频统计,结果是 词—词数 的形式,比如 请 2 ,并把结果放到txt文件中。
这样的问题利用词或单词作为字典的key,循环判断有不有这个key,没有新增一个,有的话,将这个key对应的value加1
#coding:utf-8
word_lst = []
word_dict = {}
with open("中文.txt","r") as f1 ,open("词次数.txt",'w') as f2:
for line in f1:
word_lst.append(line.split('/'))
for item in word_lst:
for item2 in item:
if item2.strip() not in ",!。“”" :
if item2 not in word_dict:
word_dict[item2] = 1
else :
word_dict[item2] += 1
for key in word_dict:
print key,word_dict[key]
f2.write(key+' '+str(word_dict[key]))
