Programming in Python Theory

Functions are the most important aspect of an application. A function can be defined as the organized block of reusable code, which can be called whenever required. Python allows us to divide a large program into the basic building blocks known as a function. The function contains the set of programming statements enclosed by {}. A function can be called multiple times to provide reusability and modularity to the Python program. The Function helps to programmer to break the program into the smaller part. It organizes the code very effectively and avoids the repetition of the code. As the program grows, function makes the program more organized. Python provide us various inbuilt functions like range() or print(). Although, the user can create its functions, which can be called user-defined functions. There are mainly two types of functions. User-define functions - The user-defined functions are those define by the user to perform the specific task. Built-in functions - The built-in fu...
