os.path module is sub module of OS module in Python used for common path name manipulation. If you try to import something then the current working directory is where it looks first, where it looks second, third and fourth depend a bit on your python installation. So, we will need to the Full path or Absolute path of the module.
This module provides a portable way of using operating system dependent functionality. inspect: This is a very handy builtin python module to check the nature of the object. The directory containing the input script (or the current directory when no file is specified). The directory from which the input script was run, or the current directory if the interpreter is being run interactively; The list of directories contained in the PYTHONPATH environment variable, if it is set. Path to the Python interpreter, or the path to a folder containing the Python interpreter. How Python search module path. sys.path is initialized from these locations:. Example 3 from drf-action-serializer. drf-action-serializer is an extension for Django REST Framework that makes it easier to configure specific serializers to use based on the client's request action. Can use variables like ${workspaceFolder} and ${workspaceFolder}/.venv .
For example, a list view should have one serializer whereas the detail view would have a different serializer. When a module named spam is imported, the interpreter first searches for a built-in module with that name. os.path.dirname() method in Python is used to get the directory name from the specified path. The way to it is by using os.path.abspath(__file__) . The easiest way to import a Python module, given the full path is to add the path to the path variable. For Python this root is the current directory or the directory where the module is located. More control flow tools in Python 3.
If not found, it then searches for a file named spam.py in a list of directories given by the variable sys.path. .
Let’s walk through each of them. Python is a programming language that lets you work quickly and integrate systems more effectively. The path variable contains the directories Python interpreter looks in for finding modules that were imported in the source files. Try this: import sys print sys.path This prints out a list of directories, when you tell Python to import something then it looks in each of the listed locations in order. sys: We will only be using this to retrieve the module object of the current package with sys.modules.
Python knows the usual control flow statements that other languages speak — if, for, while and range — with some of its own twists, of course. When the interpreter executes the above import statement, it searches for mod.py in a list of directories assembled from the following sources:. OS comes under Python’s standard utility modules. import sys import inspect import pkgutil from pathlib import Path from importlib import import_module.
