User-Defined Functions and Libraries
Learn about user-defined functions in Python and Java, focusing on definitions, parameters, return types, and syntax differences.
In Python, a user-defined function is a block of statements that does a specific task, and once defined, it can be used throughout the program. Functions are named and parametrized, and a def
keyword comes ahead, followed by the brackets containing the function name and the parameters. The function body contains the code that will be executed when the function is called.
