Python：两个文件的随机组合

Question

蟒蛇新手，忍受我。 我有两个文本文件，每个文本都有一个单词（一些有趣的单词）。 我想创建一个随机组合的第三个文件。 他们之间有空间。

例：

File1:
Smile
Sad
Noob
Happy
...

File2:
Face
Apple
Orange
...

File3:
Smile Orange
Sad Apple
Noob Face
.....

我怎么能用Python呢？

谢谢！

Answer 1

from __future__ import with_statement
import random
import os

with open('File1', 'r') as f1:
    beginnings = [word.rstrip() for word in f1]

with open('File2', 'r') as f2:
    endings = [word.rstrip() for word in f2]

with open('File3', 'w') as f3:
    for beginning in beginnings:
        f3.write('%s %s' % (beginning, random.choice(endings)))
        f3.write(os.linesep)

Answer 2

首先解析输入文件，最后得到两个列表的列表，每个列表包含文件中的单词。 我们还将在随机模块中使用shuffle方法对它们进行随机化：

from random import shuffle

words = []
for filename in ['File1', 'File2']:
  with open(filename, 'r') as file: 
    # Opening the file using the with statement will ensure that it is properly
    # closed when your done.

    words.append((line.strip() for line in file.readlines()))
    # The readlines method returns a list of the lines in the file

    shuffle(words[-1])
    # Shuffle will randomize them
    # The -1 index refers to the last item (the one we just added)

接下来，我们必须将输出字列表写入文件：

with open('File3', 'w') as out_file:
  for pair in zip(words):
    # The zip method will take one element from each list and pair them up

    out_file.write(" ".join(pair) + "\n")
    # The join method will take the pair of words and return them as a string, 
    # separated by a space.

Answer 3

import random    
list1 = [ x.strip() for x in open('file1.txt', 'r').readlines()]
list2 = [ x.strip() for x in open('file2.txt', 'r').readlines()]
random.shuffle(list1)
random.shuffle(list2)
for word1, word2 in zip(list1, list2):
    print word1, word2

Answer 4

尝试这样的事情：

file1 = []
for line in open("file1.txt"):
    file1.append(line)
#or just list(open("file1.txt"))
...
file3 = open('file3.txt','w')
file3.write(...)

并解决这个问题。 查看random模块及其功能。 （ http://docs.python.org/library/random.html ）

Answer 5

你可以做点什么

f = open(file,'r')
data = [" "]

while data[-1] != "":
    data += [f.readline()
# do this a second time for the second file

接着

out = ""
from random import randint
for x in xrange(len(data)):
     y = randint(0, len(data) -1)
     if data[y] != 0: 
        out += data[y] + "\n"
        data[y] = 0

f3 = open(third file,'w+b')
f3.write(out)

这是一个可怕的代码，但它应该工作

Answer 6

这是一个快速尝试......

import random

f1 = [line.rstrip() for line in open('file1', 'r').readlines()]
f2 = [line.rstrip() for line in open('file2', 'r').readlines()]

random.shuffle(f1)
random.shuffle(f2)
out = zip(f1, f2)

f3 = open('file3', 'w')
for k, v in out:
    f3.write(k + ' ' + v + '\n')
