Built in

Python comes with a rich set of built-in functions and types that are always available. These built-ins can help you perform a wide variety of tasks without the need for external libraries. Here's an overview of some of the most commonly used built-in functions and how they're used:

Common Built-in Functions

print(): Displays the specified message(s) or object(s) to the screen.

print("Hello, World!")

len(): Returns the length (the number of items) of an object. It can be used with most iterable types, like strings, lists, and dictionaries.

print(len("Hello"))  # Output: 5

input(): Allows the user to input data from the keyboard as a string.

name = input("What is your name? ")

Built-in Types

Python also includes several built-in data types that are frequently used. These include:

• Numeric Types: int, float, complex
• Sequence Types: list, tuple, range
• Text Type: str
• Mapping Type: dict
• Set Types: set, frozenset
• Boolean Type: bool
• Binary Types: bytes, bytearray, memoryview

Understanding and utilizing Python's built-in functions and types is crucial for efficient programming. They are optimized and provide the foundation for more complex operations in Python coding.
