Python Full Course - Detailed Topic Guide
1. Introduction to Python
- Python is a high-level, interpreted programming language known for its simplicity and readability.
- It is widely used in web development, data science, automation, and more.
- Installation: Download Python from python.org and set up using an IDE like VSCode or PyCharm.
2. Basic Syntax
- Variables store data: x = 5
- Data types include int, float, str, bool, etc.
- Use input() to take user input and print() to display output.
3. Control Structures
- Conditional: if x > 0: print('Positive')
- Loops: for i in range(5): print(i), while x < 10: x += 1
- Control: break exits loop, continue skips iteration
4. Functions
- Defined using def: def greet(name): return 'Hello ' + name
- Functions can have parameters and return values
- Scope determines variable accessibility; recursion is a function calling itself
5. Data Structures
- List: [1, 2, 3], Tuple: (1, 2), Set: {1, 2}, Dictionary: {'a': 1}
- Use methods like append(), pop(), keys(), etc.
6. String Handling
- Strings are sequences of characters: 'hello'
- Methods: upper(), lower(), replace(), split()
- String formatting: f"Hello, {name}"
7. File Handling
- Open file: open('file.txt', 'r')
