Lesson 13 — enumerate & zip
Loop smarter
enumerate(items) gives you the position and the value on each turn, so you do not need a separate counter. zip(a, b) walks two lists side by side and hands you one item from each per turn. It stops at the end of the shorter list.
colors = ["red", "green"]
for i, c in enumerate(colors):
print(i, c) # 0 red, then 1 green
Why it matters: pairing related lists (names and scores, questions and answers) is everyday work, and these two keep the loop short and safe.
