Error : "can't multiply sequence by non-int of type 'float' "

[Ala]

Hello ! Please can someone help me to resolve this error, this is the One-electron approximate form. I need to applicate this equation for all orbitals of the atoms Cadmium, Thelium and Zinc (CdTeZn). I have the orbitals number of each atom and the corresponding J, as well as the number of electrons in each orbital.

from math import exp

# Approximate one-electron profiles :
    
# Zinc Zn, atomic number = 30
# Electronic Configuration : 1s2  2s2  2p6  3s2  3p6  4s2  3d10

# Cademium Cd, atomic number = 48
# Electronic Configuration : 1s2  2s2  2p6  3s2  3p6  4s2  3d10  4p6  5s2  4d10

# Thelium Te, atomic number = 52
# Electronic Configuration : 1s2  2s2  2p6  3s2  3p6  4s2  3d10  4p6  5s2  4d10  5s2  5p4

# For Zn
n = 2
d1 = (n - 1 / n) ** 1/n
d2 = 2/n * [d1** (1-n)]
# Ji,0 = Ji (0) <=> la valeur du profil à Pz = 0
J1_30 = 2.90*10**-2  # J(i = 1s), Pz = 30   ;    
Pz = 30
# electrons number = 1

# General equation form
# Ji,A_Pz = Ji,0* ((n * d2/2) [(d1 + d2 * Ji,0 * abs(Pz)) ** (n-1)]) (exp [d1**n- ((d1 + d2 * Ji,0 * abs(Pz))**n)])

Ji,A_Pz = J1_30 * ((n * d2/2) [(d1 + d2 * J1_30 * abs(Pz)) ** (n-1)]) (exp [d1**n- ((d1 + d2 * J1_30 * abs(Pz))**n)])

Error:

This is a float number (likely):

2/n

This is a list (list is a sequence type):

[d1** (1-n)]

You cannot multiply a list by a float number. You can multiple a list by an integer, but that results in a larger list with repeats.

[3]*3 == [3, 3, 3]

Most likely I think you are using square brackets when you should be using parenthesis. This code works fine.

d2 = 2/n * (d1** (1-n))

Look through your equations and make sure you are using the correct punctuation. Aside from square brackets where there should be parenthesis I think you are missing some implied operators (missing *).

Same problem, different message. You should not be using square brackets. Square brackets are used for creating lists or indexing sequence types. You are doing niether.
