First Python Program

• Create a project in PyCharm
• Write a simple print statement
• Run the program to see output

Basic Python Concepts

• Variables: Store data temporarily
• Data Types: Integers, floats, strings, booleans
• Input/Output: Use input() to get user data, print() to display

Python Syntax and Operations

• Arithmetic Operators: Addition, subtraction, multiplication, division
• Order of Operations: Follows mathematical precedence rules

Conditional Statements

• If Statements: Execute code based on conditions
• Logical Operators: and, or, not for complex conditions
• Comparison Operators: >, <, ==, !=

Loops

• While Loops: Repeatedly execute a block of code
• For Loops: Iterate over sequences like lists or strings

Functions

• Define reusable blocks of code
• Pass parameters and return values

Data Structures
