If you run with -m to run a module, the current directory gets added to the PYTHONPATH. Check out our Code of Conduct. Python 有兩種 import 方法，absolute import 及 relative import。Absolute import 就是完整使用 module 路徑，relative import 則是使用以當前 package為參考的相對路徑。 import supergraphics.graphics . Python Package: A Python package consists of one or more modules, and it contains one file named __init__.py that tells Python that this directory is a package.The init file may be empty, or it may include code to be executed upon package initialization. Using the PYTHONPATH environment variable simplifies this process and makes importing local . If a module with the required name (in our case, config) already exists in the sys path's previous paths, the python interrupter will import it instead of our module. I think I could import and then check __file__, but I'd rather avoid that if possible. I do have a relative path from the script but when I call the script it treats that as a path . This PEP is intended to provide a solution which permits explicit relative imports from main modules, without . For each folder it cycles through every MXD file and sets them to relative paths.

I'm building a simple helper script for work that will copy a couple of template files in our codebase to the current directory. The difference between sys.path.insert and sys.path.append is that append will add the given path to the end of the sys.path's list, while insert is going to insert it at the given index(0 in our case). Python 3 has disabled implicit relative imports altogether; imports are now always interpreted as absolute, meaning that in the above example import baz will always import the top-level module. This is how you re-use code and share it among multiple files or different projects. Add a comment | Active Oldest . The first one knows how to locate built-in modules, and the second knows how to locate frozen modules. Join Paths. Relative Import In relative import, we mention the path of the imported package as relative to the location of the current script which is using the imported module. Import from path/directory. Everyone's heard about the infamous "relative path hell" in NodeJS, and while there are a lot of different solutions out there, none is standard ( cough) nor cross platform and almost all feel hacky. EDIT Nov 2014 (3 years later): Python 2.6 and 3.x supports proper relative imports, where you can avoid doing anything hacky. This is the list of directories Python looks through when it's executing: test_drink.py import unittest import sys # added! Thanks for reading! Be sure that dirBar has the __init__.py file -- this makes a directory into a Python package. To append a directory relative to this script file, you can use __file__ to get the current script's full path and build a full path to the import from there. These are: Absolute Imports Relative Imports 1. The difference between sys.path.insert and sys.path.append is that append will add the given path to the end of the sys.path's list, while insert is going to insert it at the given index(0 in our case). If we used a relative path, the path would resolve differently based on the directory from which the user is running the script, not relative to script.py's path. The import statement is the most common way of invoking the import machinery, but it is not the only way. The PYTHONPATH is by default, to some system libraries along with the folder of the original source file. $\endgroup$ - Mörkö Python Package: A Python package consists of one or more modules, and it contains one file named __init__.py that tells Python that this directory is a package.The init file may be empty, or it may include code to be executed upon package initialization. The '..' means, go to the directory above me: Use: import api.api_key # in tests, examples Run from the project directory: python -m tests.test_one. Python searches for the directories to import by going through the list. Source code: Lib/pathlib.py. import rootpath # 1. prepends root path to `sys.path` rootpath. Import statement consists of the import keyword along with the name of the module. Current working directory as a string value can be obtained the following way. However, this method is very fragile. Importing modules as run time: python -m packA.a2; Append sys.path before importing your files: import os, sys sys.path.append(os.path.dirname(os.path.dirname(os.path.realpath(__file__)))) from packA.subA import sa2 Relative Imports. And welcome to the Real Python guide to Absolute vs Relative Imports in Python. import os from typing import List path_dir: str = r"C:\Users\sselt\Documents\blog_demo" content_dir: List[str] = os.listdir(path_dir) The file is okay, but I'm more interested in file statistics, for which we have os.stat. This is how you re-use code and share it among multiple files or different projects. It is one access point to importing modules dynamically, and useful in some cases where the name of the module that needs to be imported is unknown when the code is written (for example, for plugins or extensions to an application). Relative paths in Python. The default import method is already "relative", from the PYTHONPATH. Starting with Python 2.5, in addition to the implicit relative imports described above, you can write explicit relative imports with the from module import name form of import statement. 2. print(sys.path) #%% import foo foo.fooPrint('world') Since the last part of python module search is to use the current directory you don't see the problem with the missing sys.path entry unless you actually change the working directory. New in version 3.4. Logged In: YES user_id=1038590 Patch attached that allows relative imports from a main module to work so long as: a. the top level package is either in the current directory or somewhere else on sys.path; and b. the module is executed using -m so Python knows where it fits in the package hierarchy So to get the PEP 328 example to work, you'd . #5240. When a package is imported, Python runs all of the code in the package's __init__.py file, if such a file exists. Follow asked 57 mins ago. All of the objects defined in the module or the package's __init__.py file are made available to the importer. Python 2.7 : Attempted relative import in non-package; Python 3.7 : attempted relative import with no known parent package; Why use explicit relative imports. To get the test file running regardless of where we are running Python from we need to append the relative parent directory to Python's in-built sys.pathvariable. This will import the "app" Python module from the directory above the folder in which the program with this import statement is written. But in Python you can use the so-called relative import. It provides functions to interact with the interpreter itself. Note that the path appended to sys.path is an absolute path. These explicit relative imports use leading dots to indicate the current and parent packages involved in the relative import. ¶. # utils/__init__.py from .lower import to_lower from .upper import to_upper from .length import get_length Python relative Import. import module We can also use modules that are bundled with Python, such as sys: import sys In this case, sys is a module that belongs to the Python Standard Library. You can use two different types of import statements to import a module or package to your current Python program. Pandas Transform: Preform operations on groups and concatenate the results.
