我有两个要比较的文本文件。第一个文件包含唯一的项目,第二个文件包含相同的项目但重复多次。我想看看第二个文件中每行重复多少次。这就是我写的:
import os
import sys
f1 = open('file1.txt') # this has the 27 unique lines,
f1data = f1.readlines()
f2 = open('file2.txt') # this has lines repeated various times, with a total of 11162 lines
f2data = f2.readlines()
sys.stdout = open("linecount.txt", "w")
for line1 in f1data:
linecount = 0
for line2 in f2data:
if line1 in line2:
linecount+=1
print line2, crime
问题是,当我将行计数结果加起来时,它返回11586,而不是11162.行数增加的原因是什么?
是否有另一种使用Python获取线路频率输出的方法?

https://docs.python.org/2.7/reference/expressions.html#in:
对于Unicode和字符串类型,当且仅当 x 是 y 的子字符串时,
x in y
才为真。
而不是
if line1 in line2:
我认为你打算写
if line1 == line2:
或者可以替换整个
for line2 in f2data:
if line1 in line2:
linecount+=1
阻止
if line1 in f2data:
linecount += 1
