It is available in Python 3.9 and above. The cache size is unbounded and therefore the cached dictionary can grow to enormous sizes. Example:from functools import cache @cache def fibonacci(n): if n in [0, 1]: return n else: return fibonacci(n-1) + fibonacci(n-2) print(fibonacci(4...
Python for index in range(1, 1_000_001): print(f"This is iteration {index}") The built-in range() is the constructor for Python’s range object. The range object does not store all of the one million integers it represents. Instead, the for loop creates a range_iterator from the...
Here's a fun project attempting to explain what exactly is happening under the hood for some counter-intuitive snippets and lesser-known features in Python.While some of the examples you see below may not be WTFs in the truest sense, but they'll reveal some of the interesting parts of ...
As you notice, Python 3.12 is around 40% faster than Python 3.11 for these tasks. Of course, the real speedup will depend on your code and system. TypedDict for more precise kwargs typing. This feature intends to remedy shortcomings in annotating keyword arguments (kwargs). Currently, annotat...

This approach works, but is dreadfully slow... in reality I am working with much, much larger arrays than those here. I'm looking for a way to speed this up. One thing I've noticed is that one can submit two 1D arrays to a 2-variable function and have returned a 2D...
What is the fastest way to get the reverse complement of a sequence in python? I am posting my skeleton program to test different implementations below with DNA string size 17 as an example. #!/usr/bin/env pythonimport randomimport timeitglobal complementcomplemen...
What is Queue in Python Explain with examples - A queue is a linear data structure that works on the First In First Out mechanism(FIFO).The element which enters first in the queue is the first to be processed.ExampleThe queue data structure can be unders
Remember, use the timeit module to test which of small snippets of code is faster! $ python -m timeit 'for i in range(1000000):' ' pass' 10 loops, best of 3: 90.5 msec per loop $ python -m timeit 'for i in xrange(1000000):' ' pass' 10 loops, best of 3: 51.1 ms...
