I want to update the "label"/legend parameter dynamically. It will be an integer variable coming from a function. I want the label to change every time that value in the function changes.

so i want it to say alpha = some int variable

    plt.plot(vals, smpl_sz, 'b', marker = 'o', label='alpha='**some value that updates**)
    plt.plot(val2, smpl_sz2, 'g', marker = 'o', label = 'alpha='**some value that updates** )
    plt.title('Power vs Sample Size')
    plt.xlabel('Power')
    plt.ylabel('Sample Size')
    plt.legend(loc = "lower right")

Do you mean something like `label=f'alpha={somevaluethatupdates:.0f}`? – JohanC Jan 05 '23 at 23:11
