Python Tip 🐍

In Python, you can unpack both a string and a list using the same code. ✨

# Example usage
text = "abc"
lst = [1, 2, 3]
# Unpacking works similarly for both
a, b, c = text
x, y, z = lst

Why identical arguments can create different entries in `lru_cache`? 🤔

The lru_cache creates a key not only from the values of the arguments, but also from the way they are passed.

load(True)
load(debug=True)

Although both calls pass the same value, for the cache, these are different keys, so the function will be executed twice.

print(load.cache_info())
# CacheInfo(hits=0, misses=2, ...)

The order of named arguments can also affect how an entry is created in the cache.

func(a=1, b=2)
func(b=2, a=1)

Therefore, it is best to call cached functions in a consistent style: either by position or by name, in the same order.

load(debug=True)
load(debug=True)

🔥 A consistent call format prevents unnecessary cache misses and redundant execution of expensive operations.
