# Python Topics Advanced
Welcome to the **Python Topics Advanced** repository! This repository contains advanced Python topics with explanations, examples, and interview questions to help you deepen your knowledge and prepare for technical interviews.
## Repository Contents
- [Context Manager](#context-manager)
- [Data Classes](#data-classes)
- [Decorator](#decorator)
- [Logging](#logging)
- [Typer](#typer)
- and others....
- [Interview Questions](#interview-questions)
## Context Manager
Context managers are a way to allocate and release resources precisely when you want to. The most widely used example of context managers is the `with` statement.
**Example:**
```python
with open('file.txt', 'w') as file:
file.write('Hello, World!')
```
## Data Classes
Data classes provide a decorator and functions for automatically adding generated special methods such as `__init__()` and `__repr__()` to user-defined classes.
**Example:**
```python
from dataclasses import dataclass
@dataclass
class Point:
x: int
y: int
p = Point(1, 2)
print(p) # Point(x=1, y=2)
```
## Decorator
Decorators are a design pattern in Python that allows a user to add new functionality to an existing object without modifying its structure. They are usually called before the definition of a function you want to decorate.
**Example:**
```python
def my_decorator(func):
def wrapper():
print("Something is happening before the function is called.")
func()
print("Something is happening after the function is called.")
return wrapper
@my_decorator
def say_hello():
print("Hello!")
say_hello()
```
## Logging
Logging is a means of tracking events that happen when some software runs. The logging module in Python is a standard module that provides a flexible framework for emitting log messages from Python programs.
**Example:**
```python
import logging
logging.basicConfig(level=logging.DEBUG, format='%(asctime)s - %(levelname)s - %(message)s')
logging.debug('This is a debug message')
logging.info('This is an info message')
logging.warning('This is a warning message')
logging.error('This is an error message')
logging.critical('This is a critical message')
```
## Typer
Typer is a library for building command-line interface (CLI) applications that users will love using and developers will love creating. Based on Python's type hints.
**Example:**
```python
import typer
def main(name: str):
typer.echo(f"Hello {name}")
if __name__ == "__main__":
typer.run(main)
```
