Python Data Structures: Quick Visual Guide ๐
๐น Lists: Ordered, mutable, created with [ ]
โ Access/modify via index: myList[0], myList[-1]
โ Methods: .append(), .sort(), .pop()
โ Mixed types allowed
โ Loop: for item in myList:
๐น Tuples: Immutable, ordered โ (1, 2, 3)
๐น Sets: Unordered, unique elements
๐น Dictionaries: Key-value pairs, fast lookups
๐น Arrays: Mainly for numeric data (array/NumPy)
๐ Key Points:
โ
Indexing: 0 to len-1 (forward), -1 backward
โ
Assignment myList[i] = x modifies in place
โ
Lists are the most versatile & commonly used
This is the perfect cheat sheet for beginners and for quick revision!

Decorators Are Not Magic. Theyโre Callbacks in Disguise
Youโve used @lru_cache to speed up a slow function, and it worked... until your app started eating RAM because the cache never forgot anything.
from functools import lru_cache
@lru_cache
def fib(n):
return fib(n-1) + fib(n-2) # โ Cache grows forever!
๐Hereโs whatโs really happening:
A decorator is just a function that wraps another function. When you write @lru_cache, Python replaces your fib with a new version that remembers every answer itโs ever given. Cool๐ until n goes from 1 to 100,000.
โ
Fix it like a pro:
from functools import lru_cache
@lru_cache(maxsize=128) # Only keep last 128 results
def fib(n):
if n > 1000:
return manual_calc(n) # Skip cache for huge inputs
return fib(n-1) + fib(n-2)
Now the cache stays small, predictable, and safe.
๐Bonus: Write your own @timerdecorator in 5 lines. no more time.time() spam.
