Introduction

Python is a very popular programming language. It is easy to learn and has many modules and libraries that allow you to do complex things with just a few lines of code.

A module is a Python file with some additional functions or classes. You can import a module into your Python code using the import keyword.

In this tutorial, we will show you how to create a module in Python. We will also show you how to import and use the module in your code.

What is a Module?

In Python, a module is a self-contained piece of code that can be reused in other Python programs. Modules are typically used to encapsulate functionality that can be shared across multiple programs. For example, the “math” module contains a set of functions for performing mathematical operations such as square roots and trigonometric functions.

Creating a Module
Modules are typically stored in files with a “.py” extension. To create a module, simply create a new file with this extension. For example, let’s create a file called “mymodule.py” and add the following code to it:

def greeting(name):
print(“Hello, ” + name + “!”)

This code defines a function called “greeting” which takes one parameter – “name” – and prints out a greeting message. Now, any program that wants to use this functionality can simply import the “mymodule” module and call the “greeting” function:

import mymodule
mymodule.greeting(“John”)

Creating a Module

In Python, a module is a self-contained piece of code that has an associated name. A module can define functions, classes, and variables. A module can also include other modules.

When you import a module, the Python interpreter searches for the module in the following order:

1. The current directory.
2. All directories listed in the environment variable PYTHONPATH (which you can see as sys.path within a Python interpreter session).
3. The site-packages directory of your virtualenv or sys.prefix (for Python installations from source).
4. The standard library directories (if any).

Importing a Module

A module is a Python object with arbitrarily named attributes that you can bind and reference. Simply, a module is a file consisting of Python code. A module can define functions, classes and variables. A module can also include runnable code. Modules are useful for organizing related Python code. You can import any valid Python module in your code to use its functionality.

There are different ways to import a module. You can use the import keyword, the from keyword or the imp package.

The import keyword lets you import a module in your code. For example, you can use the import keyword like this:

Code:
import mymodule
The from keyword lets you import specific members of a module in your code. For example, you can use the from keyword like this:

Code:
from mymodule import MyClass
from mymodule import myfunction
The imp package lets you access functions in a module by name instead of using from . For example, if you have a module named mymodule , you can access all members of this module without importing it by using imp like this:

Code:
def __import__(name): # Make sure we have latest copy
return _import(name)

Using a Module

Python modules are files containing Python code. This code can either be functions, classes, or variables. modules are imported from other modules using the import command.

In this example we will create a module named mymodule. The code in this module will define two functions, one called add and one called subtract.

def add(x,y):
return x + y
def subtract(x,y):
return x – y
Now we can use the module we just created by typing import mymodule at the top of our program.

import mymodule

a = mymodule.add(5,3)
b = mymodule.subtract(5,3)

print (a) #prints 8
print (b) #prints 2

Deleting a Module

It is possible to delete a module.USE the del statement to remove the module named spam.

Note: You can not delete built-in modules.

Tips and Tricks

Python is a very popular programming language. It is used in many different applications, including web development, scientific computing, and artificial intelligence. Python is relatively easy to learn, and its syntax is simple and straightforward. However, one of the things that can make Python difficult to use is its module system.

A module is a collection of code that can be reused in different programs. Python comes with a standard library of modules, but you can also create your own modules. Creating a module can be as simple as writing a single file, or it can be more complex, depending on your needs.

There are two ways to create a module in Python: using the import statement, or using the from-import statement. The import statement is the most common way to create a module. To use the import statement, you simply write “import” followed by the name of the module you want to create. For example:

The from-import statement is used when you want to import only some of the symbols from a module. For example:

You can also use the from-import statement to rename symbols when you import them. This can be useful if there are symbols in your module with names that are already used by other symbols in your program. For example:

Once you have imported a module, you can access the symbols it defines using the dot (.) operator. For example, if you have imported a module named mymodule, you can access the symbols it defines using mymodule., such as mymodule.symbol1 and mymodule.symbol2.

FAQ

Q: What is a module in Python?
A: A module is a Python object with arbitrarily named attributes that you can bind and reference.

Q: Why use modules?
A: Modules help us break down large programs into small manageable and organized files. They also help avoid duplication of code as well promote reusability.

Q: How do I create a module in Python?
Creating a module is easy. All you need to do is create a new .py file and add the following line of code at the top of the file:

module MyFirstModule
{}

Q: How do I import a module in Python?

Importing modules in Python is fairly straightforward. You can use the import keyword followed by the name of the module you want to import.

Conclusion

Modules in Python are simply Python files with a .py extension. The name of the module will be the name of the file. A Python module can have a set of functions, classes or variables defined and implemented.
