🚨 #PythonTip: 99% of devs are still sprinkling print() like confetti 🎉, meanwhile Python ships with a built-in function breakpoint() that you can drop anywhere with no imports needed. Type c to continue, n to step, or poke around in the REPL.

🧠 #PythonTip
Want to access object attributes dynamically?
Use getattr()!
code :
name = getattr(obj, "name")
✅ Cleaner than obj.__dict__
Perfect for serializers, reflection, or dynamic access! 🔁

Good morning, Pythonistas! 🐍
Today’s #PythonTip: Did you know you can use list comprehensions to make your code more readable and efficient?
💡 Example:
squares = [x**2 for x in range(4)]
print(squares)
Output:
[0, 1, 4, 9]

#PythonTip
Допустим, у вас есть строчка
y = f(x) f(x)**2
Но вы не хотите считать f(x) дважды. Что делать? Заводить новую переменную?
fx = f(x)
y = fx fx**2
Есть метод получше!
y = (lambda t: t t**2)(f(x))

#PythonTip Assume you want to execute a line:
y = f(x) f(x)**2
If you don't want to evaluate f(x) twice, you usually introduce a new variable to store f(x):
fx = f(x)
y = fx fx**2
What if you don't want to introduce new variable? Use lambda!
y = (lambda t: t t**2)(f(x))

Ends function execution and returns a result.
🖨️ print:
Outputs messages to the console.
Useful for debugging and displaying info.
Know when to use each! 👨💻👩💻

Remember, in Python indexing starts at 0, not 1. So, the first element in a list or a string is at position 0.

#PythonTip: Are you familiar with slicing? It's a quick way to access subsets of lists, strings, and other sequences. For example, list[1:3] gives the 2nd and 3rd items.
