Module Attributes in Python

Module Attributes in Python

Module attributes are variables or constants defined within a Python module. They can be accessed and used by other parts of the code that import the module. Here's a breakdown of module attributes:

1. Definition
Module attributes are declared at the top level of a module and are accessible using dot notation, such as module_name.attribute_name.

2. Examples
Let's create a Python module named example_module.py with some module attributes:

python
# example_module.py

# Module-level variables
module_variable = 42

# Module-level constant
MODULE_CONSTANT = "Hello, World!"

# Module-level function
def module_function():
    return "This is a function within the module."

3. Explanation

• The module_variable is a module attribute and can be accessed as example_module.module_variable from other parts of the code.
• MODULE_CONSTANT is a constant attribute, and its value cannot be changed once defined.
• module_function is a function attribute that can be called using example_module.module_function().

4. Importing the Module
To use the module attributes, we need to import the example_module in our main code:

python
# main.py

import example_module

# Accessing the module attributes
print(example_module.module_variable)
print(example_module.MODULE_CONSTANT)
print(example_module.module_function())

In the example above, we import the example_module and access its attributes using dot notation.

Remember to ensure both example_module.py and main.py are in the same directory or within Python's module search path.

This documentation provides an overview of module attributes in Python, along with a coding example to illustrate their usage and importance. Remember to maintain proper file structure and import statements for effective utilization of module attributes.
