Hello, checkiomates🐱‍👤!

This week's digest explores the pursuit of mastery, featuring Simon Willison's take on verifying code correctness, the importance of embracing whitespace for readability, and a guide to essential Python skills. Our mission evolves: you must now extract hidden messages with a customizable starting index.

💡TIP

On Easy difficulty, each of the few starting stations is dedicated to a distinct data type.

🏁 MISSION

Extraction II: Spy With a Head Start by freeman_lex -

The spy got trickier! Now, the secret message might start later in the string. Extend your function to accept the third parameter start with default value 0.

extraction("aqxczaqsgiunwoorkoaypablnea", 2, 3) == "casinoroyale"
extraction("PYTHON", 4, 1) == "YN"
extraction("mlhipvzeraqnfddlleetndoiie", 2, 1) == "liveandletdie"

👩‍💻CODE SHOT

What do you think the following code does?

def checkio(values: list[int]) -> list[int]:
    
    if not values: return []
    res = [values[0]]
    for i in values[1:]:
        if i >= res[-1]:
            res.append(i)
            
    return res
