How do you import a module in Python?

In Python, modules are imported using the import statement. This allows you to access functions, classes, and variables defined in another file or module, thus promoting code reuse and organization. The import statement is fundamental in Python programming as it enables developers to modularize their code, making it more manageable and readable.

When you want to use a specific module, you simply include the import statement followed by the module name. For instance, if you want to use the math module, one would write import math. After this, all the functions within the math module become accessible using the module's namespace, such as math.sqrt() for calculating the square root.

Other methods for importing modules or specific elements of modules exist, such as 'from module import function', but the primary method remains the basic import statement. This versatility and simplicity of the import statement make it crucial for any Python programmer looking to leverage existing libraries or modules.
