PYTHON BASICS
1
...
- Statements don't require explicit termination characters (e
...
, semicolons) like in some other
languages
...
**Data Types**:
- Python has various built-in data types, including integers, floating-point numbers, strings,
booleans, lists, tuples, dictionaries, and sets
...
3
...
- Loops can be implemented using while and for loops
...
**Functions**:
- Functions in Python are defined using the "def" keyword
...
5
...
- External libraries can be installed using package managers like pip
...
**File Handling**:
- Python can read from and write to files easily using built-in functions
...
**Exception Handling**:
- Errors can be handled using try, except, else, and finally blocks
...
**Object-Oriented Programming (OOP)**:
- Python supports OOP principles, including classes, objects, inheritance, and polymorphism
...
**List Comprehensions**:
- A concise way to create lists based on existing lists or other iterable objects
...
**Lambda Functions**:
- Anonymous functions defined using the lambda keyword
...
**Packages and Modules**:
- Python code can be organized into modules and packages, promoting code reusability
...
**Virtual Environments**:
- Allows isolating Python environments to manage project dependencies effectively
...
**Input and Output**:
- Input can be taken from the user using "input()" function, and output can be displayed using
"print()" function
...
**Documentation**:
- Python code is often documented using docstrings to provide useful information for developers
...
**Dynamic Memory Management**:
- Python uses automatic memory management with a garbage collector to handle memory
allocation and deallocation
...
