[英]How to modify a path which's in a variable (python)?
After finding the path of the Python file which I am actually working on with os.getcwd()
and __file__
I want to modify it, so if I put it in a variable named r
and then delete one part of the path that will be very good.在找到我实际使用
os.getcwd()
和__file__
处理的 Python 文件的路径后,我想修改它,所以如果我把它放在一个名为r
的变量中,然后删除路径的一部分,那将非常好的。 For example, the path is 'C:\\\\Users\\\\Shadow\\\\Desktop\\\\213.py'
if I want to delete \\\\213.py
from the path ( r
) how can I do that?例如,路径是
'C:\\\\Users\\\\Shadow\\\\Desktop\\\\213.py'
如果我想从路径 ( r
) 中删除\\\\213.py
我该怎么做?
you can manipulate your string:你可以操纵你的字符串:
r = 'C:\\Users\\Shadow\\Desktop\\213.py'
r.rsplit('\\', 1)[0]
output:输出:
'C:\\Users\\Shadow\\Desktop'
you may also want to have a look over pathlib.Path你可能还想看看pathlib.Path
You extract the directory name in your example.您在示例中提取目录名称。 This is easily achieved with
os.path.dirname
.这可以通过
os.path.dirname
轻松实现。
import os
os.path.dirname(__file__)
This solution is cross-platform (mostly), and avoids most pitfalls that arise from treating paths as strings.该解决方案是跨平台的(主要是),并避免了将路径视为字符串而产生的大多数陷阱。
If you need the value stored in a variable:如果您需要将值存储在变量中:
import os
r = on.path.dirname(__file__)
