17.3. Pathlib Files

17.3.1. SetUp

>>> from pathlib import Path

17.3.2. Create File

Touch creates a file

>>> myfile = Path('/tmp/myfile.txt')
>>> myfile.touch()

17.3.3. Is File

>>> myfile = Path('/tmp/myfile.txt')
>>> myfile.is_file()
True

17.3.4. Read Text

>>> myfile = Path('/tmp/myfile.txt')
>>> result = myfile.read_text()

17.3.5. Name

>>> myfile = Path('/tmp/myfile.txt')
>>> myfile.name
'myfile.txt'

17.3.6. Stem

>>> myfile = Path('/tmp/myfile.txt')
>>> myfile.stem
'myfile'

17.3.7. Parent

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

17.3.8. Suffix

>>> myfile = Path('/tmp/myfile.txt')
>>> myfile.suffix
'.txt'

17.3.9. Suffixes

>>> myfile = Path('/tmp/myfile.txt')
>>> myfile.suffixes
['.txt']

17.3.10. 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')]

17.3.11. Join Paths

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

>>> myfile = Path('/')
>>> myfile /= 'tmp'
>>> myfile /= 'mydirectory'
>>> myfile /= 'myfile.txt'
