The builtins module in Python provides a set of functions and constants that are always available without the need for import statements. These built-in functions and constants can be useful for writing more efficient and concise code.

Here are some examples of using built-in functions:

  1. len(): The len() function returns the length of a list, tuple, or string. It can be used to quickly get the number of elements in a collection.

  2. sum(): The sum() function returns the sum of all the elements in a list or tuple. It can be used to quickly compute the total of a collection of numbers.

  3. max(), min(): The max() and min() functions return the maximum and minimum values in a list or tuple, respectively. They can be used to quickly find the highest or lowest value in a collection.

  4. range(): The range() function generates a sequence of numbers. It can be used to quickly create a list of numbers without using a loop.

Here are some examples of using built-in constants:

  1. True, False: The True and False constants are used to represent boolean values in Python. They can be used to simplify boolean expressions.

  2. None: The None constant is used to represent a null value in Python. It can be used to initialize variables or to indicate that a function does not return a value.

  3. Ellipsis: The Ellipsis constant is used to represent an extended slice in Python. It can be used to create complex slices of arrays or other data structures.

By using these built-in functions and constants, you can write more efficient and concise code in Python.
