AI-102 Course: Introduction to Python

Simple syntax allows easy coding and learning.
High-level language abstracts complex details.
Open source and free to use, fostering widespread adoption.
Compatible across multiple platforms, enabling versatility.
Supports multiple programming paradigms like procedural and object-oriented.
Offers a dynamic typing system, eliminating the need for explicit type declaration.
Extensive standard library provides numerous modules and tools.
Facilitates rapid development, helping to accelerate project timelines.
Backed by a strong community that offers support and resources.
Interpreted language that executes code line by line.
Case-sensitive, distinguishing between uppercase and lowercase characters.

Integer (int): Whole numbers, including negative, positive, or zero (e.g., x = 15).
Floating Point Numbers (float): Decimal numbers (e.g., x = 3.14).
Strings (str): Sequences of characters, enclosed in quotes (e.g., name = “Ali”).
Boolean (bool): Represents true or false values (e.g., x = True).

Expressions: Combinations of values, variables, and operators that yield a value (e.g., 2 + 5 evaluates to 7).
Statements: Instructions executed by the interpreter, such as assignments and print outputs (e.g., x = 10).

input() function retrieves user input, defaults to string datatype (e.g., name = input("Enter your name: ")).
Conversion to other data types must be done explicitly (e.g., using int() to convert a string to an integer).

Concatenation: Joining strings using the + operator (e.g., result = str1 + " " + str2).
Repetition: Repeating strings with the * operator (e.g., result = str1 * 3).
Slicing: Extracting substrings using indices within square brackets (e.g., str1[0:5] gives "Hello").
Length: Determining the number of characters using len() function (e.g., print(len(str1)) returns character count).
