如何获取之前的第二个文件夹或具有特定名称的文件夹

Question

我想获取某个文件夹，这个文件夹的名称是'certainName' 或者是前两个文件夹。

myFolder = 'certainName'
myPath = r'C:/Documents/something/certainName/anotherFolder/folder'

p = pathlib.Path(myPath)
print(p.relative_to(*p.parts[-2:]))

# Another way

folder = myPath.split(myFolder)
print(folder[0])

我得到了什么

Traceback (most recent call last):
  File "model.py", line 26, in <module>
    getPrice(int(sys.argv[1]), int(sys.argv[2]), int(sys.argv[3]))
  File "model.py", line 11, in getPrice
    print(p.relative_to(*p.parts[-2:]))
  File "C:\Users\user\anaconda3\lib\pathlib.py", line 907, in relative_to
    raise ValueError("{!r} does not start with {!r}"

我想要的

'C:/Documents/something/certainName/'

Answer 1

您可以通过

获取

from pathlib import Path

myFolder = 'certainName'
myPath = r'C:/Documents/something/certainName/anotherFolder/folder'

p = Path(myPath)
print(p.parent.parent)

或

myFolder = 'certainName'
myPath = r'C:/Documents/something/certainName/anotherFolder/folder'

print('/'.join(myPath.split('/')[:-2]))
print(myPath.rsplit('/', maxsplit=2)[0])

他们都得到了

C:/Documents/something/certainName
