然后怎么输出出现次数前十的单词？？[face]emoji:010.png[/face][face]emoji:011.png[/face]

Answer 1

1 统计单词出现次数：

def count_word():
    count = {}
    keys = []
    with open('test.txt') as f:
        lines = f.readlines()
    for line in lines:
        first_word = line.split(' ')[0]
        if first_word not in keys:
            keys.append(first_word)
    count = count.fromkeys(keys,0) #fromkeys方法不会直接修改原字典，它会返回一个新字典，所以如果要使用心字典必须先赋值
    print(count)
    for line in lines:
        first_word = line.split(' ')[0]
        count[first_word] +=1
    print(count)

 2 前10出现的单词：

import re
from collections import Counter
 
with open('1.txt', 'r', ) as f:
    words = f.read()                         # 将文件的内容全部读取成一个字符串
    count = Counter(re.split(r"\W+", words))  # 以单词为分隔
 
result = count.most_common(10)                # 统计最常使用的前10个
print(result)
