16.3. Pathlib Path

  • Path.absolute() - Get the absolute path

  • Path.resolve() - Get the absolute path

  • Path.relative_to(other) - Get the relative path to another path

  • Path.match(pattern) - Check if the path matches a pattern

  • Path.is_absolute() - Check if the path is absolute

  • Path.is_relative_to(other) - Check if the path is relative to another path

  • Joining paths with the / operator

  • Path.glob() - Find files matching a pattern

  • Path.rglob() - Recursively find files matching a pattern

16.3.1. SetUp

>>> from pathlib import Path

16.3.2. Glob

SetUp:

>>> mydir = Path('/tmp/mydir/')
>>> mydir.mkdir(exist_ok=True)
>>> (mydir / 'myfile1.md').touch()
>>> (mydir / 'myfile2.md').touch()

>>> mydir.glob('*.md')
<map object at 0x...>

16.3.3. RGlob

16.3.4. Glob and Rglob

SetUp:

>>> mydir = Path('/tmp/mydir/')
>>> mydir.mkdir(exist_ok=True)
>>> (mydir / 'myfile1.md').touch()
>>> (mydir / 'myfile2.md').touch()

Usage:

>>> mydir.glob('*.md')
<map object at 0x...>
>>>
>>> sorted(mydir.glob('*.md'))
[PosixPath('/tmp/mydir/myfile1.md'), PosixPath('/tmp/mydir/myfile2.md')]

>>> sorted(mydir.rglob('*.md'))
[PosixPath('/tmp/mydir/myfile1.md'), PosixPath('/tmp/mydir/myfile2.md')]

16.3.5. Join Paths

>>> basedir = Path('/tmp')
>>> mydir = basedir / 'mydir'
>>> myfile = mydir / 'myfile.txt'
>>>
>>> myfile
PosixPath('/tmp/mydir/myfile.txt')

>>> myfile = Path('/') / 'tmp' / 'mydir' / 'myfile.txt'
>>>
>>> myfile
PosixPath('/tmp/mydir/myfile.txt')

>>> myfile = Path('/')
>>> myfile /= 'tmp'
>>> myfile /= 'mydir'
>>> myfile /= 'myfile.txt'
>>>
>>> myfile
PosixPath('/tmp/mydir/myfile.txt')
