006.【Python Basics】 Check Results with a Graph

📈 See the Results Visually with Python

Calculation results become
clear at a glance when shown as a graph.

Here, we
visualize the V–I characteristic using a graph.

✅ What You Can Do

Display calculation results as a graph
Understand behavior visually
Run everything directly in VS Code

⚡ Demo: Plotting the V–I Characteristic

import numpy as np
import matplotlib.pyplot as plt

R = 100.0

I = np.linspace(0, 0.05, 50)
V = R * I

plt.plot(I, V)
plt.xlabel("Current I [A]")
plt.ylabel("Voltage V [V]")
plt.title("V–I Characteristic (Ohm's Law)")
plt.grid(True)

plt.show()

💡 Key Points

Calculate → Run → Visualize is one continuous flow
Graphs help you understand behavior intuitively
VS Code is your workspace

📝 Summary

Python is useful not only for calculation, but also for verification
Visualizing results makes understanding faster

This is enough for Python basics.
