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. When a module named spam is imported, the interpreter first searches for a built-in module with that name. Python is a programming language that lets you work quickly and integrate systems more effectively. Python knows the usual control flow statements that other languages speak — if, for, while and range — with some of its own twists, of course. Path to the Python interpreter, or the path to a folder containing the Python interpreter. os.path.dirname() method in Python is used to get the directory name from the specified path. sys: We will only be using this to retrieve the module object of the current package with sys.modules. Let’s walk through each of them. When the interpreter executes the above import statement, it searches for mod.py in a list of directories assembled from the following sources:. Can use variables like ${workspaceFolder} and ${workspaceFolder}/.venv . Example 3 from drf-action-serializer.

For Python this root is the current directory or the directory where the module is located. 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. sys.path is initialized from these locations:. import sys import inspect import pkgutil from pathlib import Path from importlib import import_module. How Python search module path. 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. os.path module is sub module of OS module in Python used for common path name manipulation.

So, we will need to the Full path or Absolute path of the module. . inspect: This is a very handy builtin python module to check the nature of the object. For example, a list view should have one serializer whereas the detail view would have a different serializer. The way to it is by using os.path.abspath(__file__) . This module provides a portable way of using operating system dependent functionality.

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. The easiest way to import a Python module, given the full path is to add the path to the path variable.

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.
