python - 在python中读取文件并将输出写入不同的文件

问题描述

我有一个 test.txt 文件如下：

qwerty1

qwerty2

qwerty3

我想要输出如下：

test1.txt will contain: qwerty1

test2.txt will contain: qwerty2

test3.txt will contain: qwerty3

更新的问题：

我有以下文件 md5_list.txt ，其中包含：

现在我想在三个名为 md5_list1、md5_list2、md5_list3 的单独文件中获取数据。

所需输出：

在 md5_list1.txt ：

for num in range(0,no_of_files) :
        with open('md5_list.txt','r') as file:
            data = file.readlines()
            for i in data:
                if not i.startswith('\n'):
                    with open('md5_list'+str(num+1)+'.txt','a+') as finalfile:
                        finalfile.write(i)
                else:
                    break

它正在创建文件，唯一的问题是只有第一个数据块被写入每个文件。

标签： python

解决方案

以读取模式打开文件读取行检查行是否不是换行符然后写入新文件。

with open("test.txt", "r") as testfile:
    i = 1
    for line in testfile:
        if line != "\n":
            with open("test{}.txt".format(i), "w+") as newfile:
                newfile.write(line)
            i += 1

更新：

with open("test.txt", "r") as testfile:
    i = 1
    for line in testfile:
        if line == "\n":
            i += 1
        else:
            with open("test{}.txt".format(i), "a") as newfile:
                newfile.writelines(line)
