There are two types of functions in Python: 1. User-defined functions 2. Built-in (system-defined) functions
User-defined Functions: These are functions created by the developer to fulfill specific needs within the program. Developers can define these functions according to their requirements and can use them multiple times within the program.
Built-in (System-defined) Functions: These are predefined functions provided by Python, such as print(), len(), range(), etc. They are part of Python’s standard library and can be used directly without needing to be defined by the user.
