我试图同时从几个文本文件中提取数据。
import fileinput
num_lines = sum(1 for line in open('2grams.txt')) ## in order not to print junk
count = 0
f0 = open("2gram_glues.txt", 'r')
f1 = open("2grams.txt", 'r')
f2 = open("output.txt", 'w')
f3 = open('2mwus.txt', 'r')
with fileinput.input(files=('2grams.txt', '2gram_glues.txt', '2mwus.txt')) as f:
for line in f:
f3.seek(0, 0)
for line1 in f3:
if line == line1:
f2.write("The 2 Gram is: " + line.strip() + "\t The score is: " + f0.readline())
count += 1
if count >= num_lines:
break
f0.close()
f1.close()
f2.close()
f3.close()
2grams.txt和2gram_glues.txt分别具有相同数量的行和数据（在这些行上），但是，我实际上要写入输出文件的数据是2mwus.txt中与数据相交的数据2grams.txt具有不同的行数。
问题是我要打印与2gram_glues.txt串联的2mwus.txt（包含一个分数）。
我从2gram_glues.txt获得的分数是有序的，而不是2mwus.txt的分数。
写数据时我做错了什么？

我认为您不需要使用fileinput：
num_lines = sum(1 for line in open('2grams.txt')) ## in order not to print junk
count = 0
intersect = open('2grams.txt', 'r')
out_file = open("output.txt", 'w')
scores = open("2gram_glues.txt", 'r')
with open('2mwus.txt', 'r') as base:
for line in base:
line = line.rstrip()
number = line[-2:]
number = int(number.lstrip())
line = line[:-2]
line = line.rstrip()
intersect.seek(0, 0)
scores_lines=scores.readlines()
scores.seek(0, 0)
for i, line_intersect in enumerate(intersect):
line_intersect= line_intersect.rstrip()
if line == line_intersect:
print("**The 2 Gram is: " + line.strip() + "\t The score is: " + scores_lines[i] +
'The number is ' + str(number))
count += 1
if count >= num_lines:
break
intersect.close()
out_file.close()
scores.close()
从：
'(850,·900,\t12·'
'(frequencies·850,\t4·'
'phone·but\t2·'
#\t denotes tabulation, · denotes spaces
使用：
line = line.rstrip()
使得：
'(850,·900,\t12'
'(frequencies·850,\t4'
'phone·but\t2'
然后得到数字：
number = line[-2:]
给出：
'12'
'\t4'
'\t2'
然后左剥离数字：
number = int(number.lstrip())
给出：
12
4
2
继续我们的“路线”：
'(850,·900,\t12'
'(frequencies·850,\t4'
'phone·but\t2'
使用
line = line[:-2]
line = line.rstrip()
给出：
'(850, 900,'
'(frequencies 850,'
'phone but'
有点麻烦，但避免使用RegEx的必要性
