如何建立新资料夹? [英] How to create new folder?

问题描述

我想将程序的输出信息放置到一个文件夹中.如果给定的文件夹不存在，则程序应使用程序中给定的文件夹名称创建一个新文件夹.这可能吗?如果可以，请告诉我.

假设我给定了"C:\Program Files\alex"之类的文件夹路径，并且alex文件夹不存在，那么程序应该创建alex文件夹，并将输出信息放置在alex文件夹中.

解决方案

您可以使用 os.path .exists()来查看它是否已经存在:

newpath = r'C:\Program Files\arbitrary' 
if not os.path.exists(newpath):
    os.makedirs(newpath)

如果您要制作安装程序: Windows Installer 为您做了很多工作. /p>

I want to put output information of my program to a folder. if given folder does not exist, then the program should create a new folder with folder name as given in the program. Is this possible? If yes, please let me know how.

Suppose I have given folder path like "C:\Program Files\alex" and alex folder doesn't exist then program should create alex folder and should put output information in the alex folder.

解决方案

You can create a folder with os.makedirs()
and use os.path.exists() to see if it already exists:

newpath = r'C:\Program Files\arbitrary' 
if not os.path.exists(newpath):
    os.makedirs(newpath)

If you're trying to make an installer: Windows Installer does a lot of work for you.
