Boolean Literals and Special Literals

Two boolean literals: True and False.
Special literal representing absence of value: None.

Operators and Punctuators

Operators perform operations on variables and values (e.g., arithmetic, comparison, logical).
Punctuators, also known as delimiters, define the structure and layout of code.

Examples of Punctuators

Common punctuators in Python: parentheses (), brackets [], braces {}, commas ,, colons :, and semicolons ;.

Keywords and Identifiers

Python keywords are reserved words with predefined meanings (e.g., if, else, for, while).
Identifiers are names given to entities like variables and functions, crucial for code readability and functionality.

Case Sensitivity

Python is case-sensitive in identifiers, meaning variable and Variable are distinct names.

Identifier Rules

Identifiers must start with a letter (a-z, A-Z) or an underscore (_), followed by letters, digits (0-9), or underscores.

Python Keywords Count

Currently, there are 35 keywords in Python.

Python Development Contribution

Python’s key characteristic is its open-source nature, enabling anyone to contribute to its development.

Interactive Features

Python provides an interactive shell for real-time testing and debugging of code snippets.

Portability

Python ensures portability via bytecode compilation, allowing code to run on different hardware and operating systems.

Modules for Efficiency

External modules and libraries, like NumPy and Pandas, can be integrated into Python to enhance performance and functionality.

GUI Application Support

The Tkinter library is a major feature of Python that facilitates the creation of graphical user interface (GUI) applications.

Structure for Large Programs

Python provides better structure and support through features like modules and functions, making it more suitable for large-scale applications compared to shell scripting.
