What is the difference between a list and a tuple in Python?

The distinction between a list and a tuple in Python primarily revolves around mutability. A list is mutable, meaning that you can modify its contents by adding, removing, or changing elements after the list has been created. This flexibility allows for dynamic data management, which is particularly useful when you need to store a collection of items that may change over time.

In contrast, a tuple is immutable, which means that once it is created, its contents cannot be altered. This property makes tuples ideal for use cases where you want to ensure that a collection of items remains constant throughout the program. For example, tuples can be used to store fixed sets of values, such as coordinates or records that should not change.

This fundamental difference affects how each data type is used in programming. Lists are frequently used for collections that require modifications, while tuples are typically used for collections of items that should remain static. Understanding this distinction helps developers choose the appropriate data structure based on the requirements of their applications.
