how display labels edges and color with dictionary? ​

edit

Hi

How can I label edges style :edge (0,1) ='01' and give them a color like in the simplex1ColorRevDic dictionary ?

# functions
def strListToList(strL) :
    Lstr=strL.replace('[','').replace(']','').split(',')
    return [SR(e) for e in Lstr]

    # add axis for real part
    plt += arrow3d((0, 0, 0), (xBound, 0, 0), color='red',width=wA,radius=rA)
    plt += text3d("ex", (xBound, 0, 0), fontsize='200%', color='black')
    plt += arrow3d((0, 0, 0), (0, yBound, 0), color='gray',width=wA,radius=rA)
    plt += text3d("ey", (0, yBound, 0), fontsize='200%', color='gray')
    plt += arrow3d((0, 0, 0), (0, 0, zBound), color='pink',width=wA,radius=rA)
    plt += text3d("ez", (0,0, zBound), fontsize='200%', color='pink')
    plt+=textToPlt
    return plt
