The os.environ documentation does state it’s a mapping: A mapping object representing the string environment. As such it behaves according to the python mapping documentation of which dict is the standard implementation. os.environ therefor behaves just like the standard dict, it has all the same methods: >>> import os >>> len(os.environ) 36 >>> ‘USER’ in … Read more
import os os.path.basename(os.path.dirname(os.path.realpath(__file__))) Broken down: currentFile = __file__ # May be ‘my_script’, or ‘./my_script’ or # ‘/home/user/test/my_script.py’ depending on exactly how # the script was run/loaded. realPath = os.path.realpath(currentFile) # /home/user/test/my_script.py dirPath = os.path.dirname(realPath) # /home/user/test dirName = os.path.basename(dirPath) # test
os.rename(), os.replace(), or shutil.move() All employ the same syntax: import os import shutil os.rename(“path/to/current/file.foo”, “path/to/new/destination/for/file.foo”) os.replace(“path/to/current/file.foo”, “path/to/new/destination/for/file.foo”) shutil.move(“path/to/current/file.foo”, “path/to/new/destination/for/file.foo”) The filename (“file.foo”) must be included in both the source and destination arguments. If it differs between the two, the file will be renamed as well as moved. The directory within which the new file is … Read more
It looks like there is a parents element that contains all the parent directories of a given path. E.g., if you start with: >>> import pathlib >>> p = pathlib.Path(‘/path/to/my/file’) Then p.parents[0] is the directory containing file: >>> p.parents[0] PosixPath(‘/path/to/my’) …and p.parents[1] will be the next directory up: >>> p.parents[1] PosixPath(‘/path/to’) Etc. p.parent is another … Read more
See this related thread. Basically, os.environ is found on import, and os.getenv is a wrapper to os.environ.get, at least in CPython. EDIT: To respond to a comment, in CPython, os.getenv is basically a shortcut to os.environ.get ; since os.environ is loaded at import of os, and only then, the same holds for os.getenv.
os.rename(), os.replace(), or shutil.move() All employ the same syntax: import os import shutil os.rename(“path/to/current/file.foo”, “path/to/new/destination/for/file.foo”) os.replace(“path/to/current/file.foo”, “path/to/new/destination/for/file.foo”) shutil.move(“path/to/current/file.foo”, “path/to/new/destination/for/file.foo”) Note that you must include the file name (file.foo) in both the source and destination arguments. If it is changed, the file will be renamed as well as moved. Note also that in the first two … Read more
