🐍 Python Flow Control - Complete Tutorial | Beginner to Advanced Master Python's conditional statements, operators, and control flow in this comprehensive tutorial! Perfect for beginners and students learning programming fundamentals. 📚 TOPICS COVERED: ✅ OPERATORS: Comparison Operators Logical Operators: and, or, not Truth tables and Boolean logic Short-circuit evaluation Operator precedence hierarchy ✅ ERROR HANDLING: Syntax Errors (Compile-Time) Runtime Errors (Exceptions) Logical Errors (Semantic) ValueError, TypeError, ZeroDivisionError NameError, IndexError, KeyError Try-Except blocks Error handling best practices ✅ TYPE CONVERSION: str(), int(), float(), bool() String concatenation with numbers Type casting vs Type conversion Implicit casting (automatic) Explicit casting (manual) Common conversion pitfalls ✅ TRUTHINESS & FALSINESS: Falsy values in Python (0, "", [], {}, None, False) Truthy values (everything else) Boolean context evaluation Using truthiness for cleaner code Logical operators with non-Boolean values ✅ CONDITIONAL STATEMENTS: Simple IF statement IF-ELSE (two-way decisions) IF-ELIF-ELSE (multiple conditions) Nested IF statements When to use which structure Real-world decision-making examples ✅ INDENTATION: What is indentation and why it matters 4 spaces vs tabs Indentation errors ✅ ADVANCED TOPICS: eval() function - usage and security risks Safe alternatives to eval() Exception handling with try-except Multiple exception types try-except-else-finally structure By the end of this tutorial, you will: ✓ Master all comparison and logical operators ✓ Understand operator precedence and evaluation order ✓ Handle errors gracefully with try-except ✓ Convert between different data types confidently ✓ Use truthiness to write cleaner Python code ✓ Make decisions with IF statements effectively ✓ Write properly indented, readable code ✓ Avoid common beginner mistakes ✓ Build real-world applications ✓ Debug your code efficiently ⏰ LAST UPDATED: December 2025 - All content current with Python 3.12 © 2025 [Aya Nabil Alharazin].
