如何在Python中使用文本文件中的行作为输入？

Question

如果这是一个非常简单的问题，我很抱歉…我对Python完全陌生，并在不断学习。在

一篇旧文章（Find all combinations (upper and lower and symbols) of a word in python）展示了一种将一个输入词进行多重排列的方法。代码运行得很好，但是显示的代码只允许输入一个单词；在本例中是Password。在

我想使用一个文本文件，每行一个单词，作为上面链接中显示的代码段的输入，并将结果保存到一个新的文本文件中。在

我本以为这很简单：以只读方式打开输入文件，打开输出文件进行写入，用填充读取线（）写入def并将结果写入输出文件。冲洗并重复。然而，尽管尝试了一些不同的方法和语法，我还是不能让它发挥作用。在

我修改moose代码的拙劣尝试如下：

#!/usr/bin/python
# -*- coding: utf-8 -*-

from itertools import product

def getAllCombinations(password):
    leet = ["Aa@","Bb","Cc", "Dd","Ee","Ff","Gg","Hh","Ii","Jj","Kk",
            "Ll","Mm","Nn","Oo0","Pp","Qq","Rr","Ss5","Tt","Uu","Vv",
            "Ww","Xx","Yy","Zz"]

    getPlaces = lambda password: [leet[ord(el.upper()) - 65] for el in password]

    for letters in product(*getPlaces(password)):
        yield "".join(letters)

with open("wordlist_in.txt", "r") as infile, open("wordlist_out.txt", "w") as outfile:
    data = infile.readlines()
    for el in getAllCombinations(data):    <<<Pretty sure this is where I go wrong
        outfile.write(el+'\n')

如何获取文件每行中包含的字符串作为getAllCombinations的输入？在

在听取了帕特里克·卡罗尔、pzp和本·格雷厄姆的建议后（谢谢你的回复！）！！我肯定会看看你提出的一些改进代码的方法。）经过反复试验，我发现我最初的尝试并没有太大的错误，我自己至少有一次成功了，除了一个小问题。在

我输入单词表中的每个单词都在自己的行上。当Python读取文件时，它将不可见的'\n'控制字符作为单词的一部分，例如alpha变成alpha\n。这个控制字符使Python函数异常。通过插入一行新行并使用rstrip（），我能够纠正问题，代码运行得非常完美。在

以下是最终修改后的代码（原始代码全部归功于@moose）：

#!/usr/bin/python
# -*- coding: utf-8 -*-

from itertools import product

def getAllCombinations(password):
    leet = ["Aa@","Bb","Cc", "Dd","Ee","Ff","Gg","Hh","Ii","Jj","Kk",
            "Ll","Mm","Nn","Oo0","Pp","Qq","Rr","Ss5","Tt","Uu","Vv",
            "Ww","Xx","Yy","Zz"]

    getPlaces = lambda password: [leet[ord(el.upper()) - 65] for el in password]

    for letters in product(*getPlaces(password)):
        yield "".join(letters)

with open("wordlist_in.txt", "r") as infile, open("wordlist_out.txt", "w") as outfile:
    data = infile.readlines()
    for line in data:
        line=line.rstrip('\n')
        for el in getAllCombinations(data):
            outfile.write(el+'\n')

编码愉快

我猜你的单词表_英寸.txt看起来像这样

word1
another_word
more_words

在这种情况下，一次只需要向函数传递一个字：

^{pr2}$
