Matplotlib - Real-World Visualization Patterns

Find the mistake in this dashboard layout code:

fig, axs = plt.subplots(1, 3)
for i in range(4):
    axs[i].plot([1, 2, 3], [3, 2, 1])

ATypeError because axs is not iterable

BSyntaxError due to missing colon

CNo mistake, code runs correctly

DIndexError because axs has only 3 elements but loop runs 4 times

Step-by-Step Solution

Solution:

Step 1: Check axs length
plt.subplots(1, 3) creates 3 subplots, so axs has length 3 with indices 0,1,2.
Step 2: Analyze loop range
The loop runs from 0 to 3 (4 times), so axs[3] access causes IndexError.
Final Answer:
IndexError because axs has only 3 elements but loop runs 4 times -> Option D
Quick Check:
Loop index exceeds axs size = C [OK]

Quick Trick: Loop indices must match subplot count [OK]
