    Function composition is a programming technique where multiple functions are combined such that the output of one function becomes the input of the next. This approach is widely used to build modular, reusable, and maintainable code. In Python, function composition is not built-in but can be implemented using various techniques.

    Basic Function Composition

    In Python, you can compose functions manually by nesting them. For example:

    def add(x):
    return x + 2

    def multiply(x):
    return x * 2

    result = multiply(add(5)) # First add(5) ā†’ 7, then multiply(7) ā†’ 14
    print(result)
    Gekopieerd.

    This approach is straightforward but becomes cumbersome when dealing with multiple functions.

    Creating a Composition Utility

    To simplify the process, you can create a utility function to compose two or more functions:

    def compose(f, g):
    return lambda x: f(g(x))

    def add(x):
    return x + 2

    def multiply(x):
    return x * 2

    composed_function = compose(multiply, add)
    result = composed_function(5) # Equivalent to multiply(add(5))
    print(result)
    Gekopieerd.

    This utility makes it easier to reuse and chain functions dynamically.
