Welcome to the advanced Python tutorial! Dive deeper into powerful concepts that will elevate your coding skills. Let's explore key topics together:
1. Decorators 🎒
Decorators allow you to modify or enhance functions without changing their code.
Example:
def my_decorator(func):
def wrapper():
print("Before function call")
func()
print("After function call")
return wrapper
@my_decorator
def say_hello():
print("Hello!")
say_hello()
📌 Output:
Before function call
Hello!
After function call
2. Generators 🧠
Generators are functions that yield values instead of returning them.
Syntax:
def count_up_to(n):
count = 1
while count <= n:
yield count
count += 1
Run for num in count_up_to(5): print(num)
to see the sequence!
3. Context Managers 📁
Use with
statements to manage resources safely.
Example:
with open("file.txt", "r") as f:
content = f.read()
This ensures proper file closure automatically.
4. Metaclasses 🔍
Metaclasses define class creation behavior.
Basic usage:
class MyMeta(type):
def __new__(cls, name, bases, attrs):
return super().__new__(cls, name, bases, attrs)
Use metaclass=MyMeta
in your class definitions.
5. Concurrency vs Parallelism 🔄
- Concurrency: Handling multiple tasks in a single process
- Parallelism: Executing multiple tasks simultaneously
Useconcurrent.futures
ormultiprocessing
for advanced task management.
