python3 - os.path更改

Question

I am using python 3.3 in Windows 7.

The python file, main.py is in D:\\my proj\\$MY\\1

I wrote the following code in that file:

import os

file_usage = "usage.txt"
p1 = os.getcwd()
print ("os.getcwd(): ", p1)

p5 = os.path.join(p1,"report")
print ("os.path.join: ", p5)

file = open(file_usage, "a")
file.write ("*****BLAH-BLAH*****")
file.close()

So, When I run my program in cmd, it gives me output like:

os.getcwd():  D:\my proj\$MY\1
os.path.join:  D:\my proj\$MY\1\report

Now, usage.txt file is generating in the directory where my main.py is located means inside the 1 folder.

But I have tried to modify the path that it should be saved in report folder as you can see the value of os.path.join .

So, I want to save the generated usage.txt in the report folder instead of 1 . What type of changes should I do? or what other modules do I need to use?

I'm a novice user. So, please try to tell me in-depth or send me links from where I can get more knowledge or examples related to this. I'm awaiting for your reply.

Answer 1

open(os.path.join(p5, "usage.txt"), "w")

由于p5是报告目录的路径，因此将在该目录中打开usage.txt文件。
