What are lists, tuples, and dictionaries in Python?

In Python, lists, tuples, and dictionaries are three commonly used data structures that serve different purposes:

1. Lists:

   • Lists are ordered, mutable (changeable), and allow duplicate elements.
   • They are defined by square brackets [] and elements are separated by commas.
   • Example: my_list = [1, 2, 3, 'apple', 'banana']
   • Lists are useful when you need to store a collection of items that may change over time.

2. Tuples:

   • Tuples are ordered, immutable (unchangeable), and allow duplicate elements.
   • They are defined by parentheses () and elements are separated by commas.
   • Example: my_tuple = (1, 2, 3, 'apple', 'banana')
   • Tuples are useful when you need to store a collection of items that should not change, providing a fixed set of values.

3. Dictionaries:

   • Dictionaries are unordered, mutable, and do not allow duplicate keys.
   • They are defined by curly braces {} and consist of key-value pairs separated by commas.
   • Example: my_dict = {'name': 'Alice', 'age': 25, 'city': 'New York'}
   • Dictionaries are useful when you need to store data in a way that allows for quick lookups based on keys.

In the context of cloud computing, these data structures can be used in various applications running on platforms like Tencent Cloud. For instance, you might use dictionaries to manage configuration settings for a cloud service, lists to store a sequence of tasks to be executed, or tuples to represent immutable data such as user credentials.
