In Python, how do I comment out a specific part of the code only?

Question

plt.plot (X, Y, label='xyz1', linewidth=2, linestyle='--', color='red', marker='v')

I don't want to delete linewidth=2, but only comment out that portion, in case I want it for future use. How do I do it?

I tried something like this but it didn't work:

plt.plot (X, Y, label='xyz1', #linewidth=2,\# linestyle='--', color='red', marker='v')
