在不更改目录的情况下用Python写入新目录 [英] Writing to a new directory in Python without changing directory

问题描述

当前，我有以下代码...

Currently, I have the following code...

file_name = content.split('=')[1].replace('"', '') #file, gotten previously
fileName = "/" + self.feed + "/" + self.address + "/" + file_name #add folders 
output = open(file_name, 'wb')
output.write(url.read())
output.close()

我的目标是让python将文件(在file_name下)写入当前目录(即python脚本所在的目录)"feed"文件夹中"address"文件夹中的文件中.

My goal is to have python write the file (under file_name) to a file in the "address" folder in the "feed" folder in the current directory (IE, where the python script is saved)

我已经研究了os模块，但是我不想更改我的当前目录，并且这些目录还不存在.

I've looked into the os module, but I don't want to change my current directory and these directories do not already exist.

推荐答案

首先，我不是100％确信我理解这个问题，所以让我说一下我的假设:1)您要写入尚不存在的目录中的文件.2)路径是相对的(相对于当前目录).3)您不想更改当前目录.

First, I'm not 100% confident I understand the question, so let me state my assumption: 1) You want to write to a file in a directory that doesn't exist yet. 2) The path is relative (to the current directory). 3) You don't want to change the current directory.

因此，鉴于:检查以下两个函数:os.makedirs和os.path.join.由于您要指定相对路径(相对于当前目录)，因此您不想添加初始的"/".

So, given that: Check out these two functions: os.makedirs and os.path.join. Since you want to specify a relative path (with respect to the current directory) you don't want to add the initial "/".

dir_path = os.path.join(self.feed, self.address)  # will return 'feed/address'
os.makedirs(dir_path)                             # create directory [current_path]/feed/address
output = open(os.path.join(dir_path, file_name), 'wb')
