Syntax and Data Types of Python

Python's hallmark is its clear and intuitive syntax, making it an ideal language for newcomers to programming. The language uses indentation to define code blocks instead of traditional curly braces, enhancing readability.

Variables in Python are dynamically typed, meaning their data types are determined at runtime. Python Data Types includes integers, floating-point numbers, strings, lists, tuples, dictionaries, and more.

1) Integers: Integers are whole numbers, both positive and negative, without any decimal point. They can be represented as numbers like 1, -42, 0, etc.

2) Floating-point numbers: Floating-point numbers, or floats, represent real numbers with decimal points or in scientific notation (e.g., 3.14, -0.001, 1.23e-4). They are used to handle numbers with fractional parts.

3) Strings: Strings are sequences of characters commonly used to represent text data. In the context of Python String, they can be enclosed in single (''), double ("") or triple (''' or ""'') quotes.

4) Lists: Lists are ordered collections of items. They can contain elements of different Data Types, including other lists. Lists are mutable, meaning you can change their content (add, remove, or modify elements).

5) Tuples: Python Tuples are like lists, but they are immutable. It means that once created, their contents cannot be changed. They are typically used to represent fixed collections of items, such as coordinates or records.

6) Dictionaries: Dictionaries are unordered collections of key-value pairs. They are used for storing and retrieving data using a unique key. Keys are unique and immutable, and they are used to access associated values.

Here's a Python program showing the syntax and dynamically typed nature of the language:

Python's built-in functions and libraries make it easy to work with these data types, enabling developers to manipulate and analyse data efficiently.
