Matplotlib - Performance and Large Data

Identify the error in this code snippet:

import matplotlib.pyplot as plt
for i in range(5):
    fig = plt.figure()
    plt.plot([1,2,3], [4,5,6])
plt.close(fig)

ANo error, code runs correctly

Bplt.close(fig) is called outside the loop, closing only last figure

Cplt.close() cannot accept figure objects

Dplt.plot() is called without specifying figure

Step-by-Step Solution

Solution:

Step 1: Check where plt.close(fig) is called
plt.close(fig) is outside the loop, so only last figure is closed.
Step 2: Effect on memory
First 4 figures remain open, causing unnecessary memory use.
Final Answer:
plt.close(fig) is called outside the loop, closing only last figure -> Option B
Quick Check:
Close inside loop to free all figures [OK]

Quick Trick: Close each figure inside loop to avoid memory leaks [OK]
