Matplotlib - Seaborn Integration

Identify the error in this code snippet that tries to add a legend:

import matplotlib.pyplot as plt
plt.plot([1, 2, 3], label='Line 1')
plt.legend()
plt.show()

AThe plot function is missing y-values

BThe legend function is called before plot

CThe label parameter is invalid in plot

DThere is no error; the code runs correctly

Step-by-Step Solution

Solution:

Step 1: Check plot function parameters
The plot call has only one list, so it treats it as y-values with x as indices 0,1,2.
Step 2: Understand matplotlib behavior
This is valid syntax; it plots y-values against default x-values. So no error here.
Step 3: Re-examine options carefully
The plot function is missing y-values says missing y-values, but y-values are given. The legend function is called before plot is wrong order. The label parameter is invalid in plot label is valid. There is no error; the code runs correctly says no error.
Final Answer:
There is no error; the code runs correctly -> Option D
Quick Check:
Code runs fine with legend after plot [OK]

Quick Trick: Check if plot syntax matches matplotlib docs [OK]
