How to Import File in Python Python language has a way to put definitions in one file and use them in the script or an interactive instance of the interpreter. Such a file is called the module ; definitions from a module can be imported into other modules or into the main module (the collection of variables that you have access to in the script executed at the top level and in calculator mode) You do not have many complex methods to import a python file from one folder to another. Just create a __init__.py file to declare this folder is a python package and then go to your host file where you want to import just type . from root.parent.folder.file import variable, class, whateve .py in Python's import path, then you won't be able to import math from the standard library. This isn't always the case, though. Create a file named time.py with the following content: # time.py print (Now's the time!) Next, open a Python interpreter and import this new module: >>> >>> import time >>> # Nothing is printed >>> time. ctime 'Mon.

- Import doc. The __init__.py files are required to make Python treat the directories as containing packages, this is done to prevent directories with a common name, such as string, from unintentionally hiding valid modules that occur later on the module search path.. __init__.py can just be an empty file, but it can also execute initialization code for the package or set the __all__ variable

- The import system¶ Python code in one module gains access to the code in another module by the process of importing it.

Functions such as importlib.import_module() and built-in __import__() can also be used to invoke the import machinery
- Import class from a file in a different directory Packages. The most Pythonic way to import classes from other directories is by using packages.

6.1.3. Compiled Python files¶. To speed up loading modules, Python caches the compiled version of each module in the __pycache__ directory under the name module. version.pyc, where the version encodes the format of the compiled file; it generally contains the Python version number.For example, in CPython release 3.3 the compiled version of spam.py would be cached as __pycache__/spam. But before we start, here is a template that you may use in Python to import your Excel file: import pandas as pd df = pd.read_excel (r'Path where the Excel file is stored\File name.xlsx') print (df) Note that for an earlier version of Excel, you may need to use the file extension of 'xls
A Python file called hello.py has the module name of hello that can be imported into other Python files or used on the Python command line interpreter. You can learn about creating your own modules by reading How To Write Modules in Python 3. Modules can define functions, classes, and variables that you can reference in other Python .py files. Importing and using a package is just like importing a .py file however Python treats the entire test directory as the package itself. This means you need to run Python from above the test directory so Python can find the package. Also note be sure you don't have a test.py file in the same directory as the test package! If you do Python could get confused and import the test.py file instead of. For example, since packB lacks a __init__.py file, calling import packB (in Python 3.3+) has very little use because no objects in the packB package are made available. A subsequent call to packB.b1 would fail because it has not been imported yet. Absolute vs. Relative Import.
