A Python module is a file containing Python definitions and statements. A module can define functions, classes, and variables. A module can also include runnable code. Grouping related code into a module makes the code easier to understand and use. It also makes the code logically organized.
To create a Python module, write the desired code and save that in a file with.py extension. Let’s understand it better with an example: Example: Let’s create a simple calc.py in which we define two functions, one addand another subtract.
We can import the functions, and classes defined in a module to another module using the import statementin some other Python source file. When the interpreter encounters an import statement, it imports the module if the module is present in the search path. Note: A search path is a list of directories that the interpreter searches for importing a ...
Python’s from statement lets you import specific attributes from a module without importing the module as a whole.
The * symbol used with the import statement is used to import all the names from a module to a current namespace. Syntax:
Whenever a module is imported in Python the interpreter looks for several locations. First, it will check for the built-in module, if not found then it looks for a list of directories defined in the sys.path. Python interpreter searches for the module in the following manner – 1. First, it searches for the module in the current directory. 2. If the...
There are several built-in modules in Python, which you can import whenever you like. Output: We have covered Python Modules and it’s operations like create, import, etc. This article will give the overview about Python modules so that you can easily create and use modules in Python.
Import Python Standard Library Modules. The Python standard library contains well over 200 modules. We can import a module according to our needs. Suppose we want to get the value of pi, first we import the math module and use math.pi. For example,

2 days ago · Note that relative imports are based on the name of the current module. Since the name of the main module is always "__main__", modules intended for use as the main module of a Python application must always use absolute imports. 6.4.3. Packages in Multiple Directories¶ Packages support one more special attribute, __path__.
Remember, the right use of Python modules not only lays the foundation for robust code but also transforms your programming workflow, making it more efficient and pleasurable. By investing in learning how to effectively utilize modules, you’re not just coding; you’re crafting a scalable and organized masterpiece.
Naming a Module. You can name the module file whatever you like, but it must have the file extension .py. Re-naming a Module. You can create an alias when you import a module, by using the as keyword:

Mar 2, 2024 · Think of a module as a toolbox. Just like a carpenter reaches for a hammer or a screwdriver neatly organized within a toolbox, a Python programmer can access functions, variables, and classes from a module. In the area of programming, especially in Python, modules are essential for creating organized, manageable, and reusable code.
