I dislike Python’s native string for complex numbers, and so wrote my own:

def str (z):
    result = f"{z.a}"
    if (z.b < 0.0):
        result += " - "
    else:
        result += " + "
    result += f"{abs(z.b)}i"
    return result

I saw the article here about overriding a function at the instance level, but is it possible to override str in complex’s class? That is, any complex number I instance would use my str function?
