主代码

import sys
from vector import vector
from sketch import sketch
# 测试文档列表
filenames = ['a.txt','b.txt','c.txt']
k = 5 #k-grams
d = 10000 #文档摘要维度
sketches = [0 for i in filenames]
print("sketches: " , sketches)
for i in range(len(filenames)):
with open(filenames[i], 'r', encoding='utf-8') as f:
text = f.read()
sketches[i] = sketch(text, k, d)
# print("sketches[i]: " , sketches[i],'\n\n\n')
# 输出结果标题
print(' ' * 20, end = ' ')
for filename in filenames:
print('{:>25}'.format(filename), end = ' ')
print()
# 输出结果比较明细
for i in range(len(filenames)):
print('{:10}'.format(filenames[i]), end = ' ')
for j in range(len(filenames)):
print('{: <22}'.format(sketches[i].similarto(sketches[j])), end = ' ')
print()

用到的2个库文件：

求教下各位懂python的大佬。

感谢大佬的帮助！维度 d 设置 1000 时，au3的计算速度真的比python逊色太多了
