This is my script, it's to draw a curve of the tension squared as a function of the inverse of the distance squared:

import numpy as np
import matplotlib.pyplot as plt

plt.title("Courbe de la tension en fonction de la distance à l'émeteur")

d = [0.1,0.12,0.15,0.2,0.25,0.3,0.4]
A = []
for n in range (len(d)):
A.append (1/(d[n]**2))

U = [0.456,0.340,0.304,0.224,0.172,0.152,0.116]

B = [ ]
for n in range (len(U)):
B.append (U[n]**2)

plt.plot(B, A)

plt.xlabel("inverse de la distance en m au carré")
plt.ylabel("tension au carrée")

modele= np.polyfit(A,B,1)
plt.plot(A, modele[0]*A + modele[1])

plt.show()


And this is the error:

Traceback (most recent call last):
File "<module1>", line 23, in <module>
TypeError: can't multiply sequence by non-int of type 'numpy.float64'
>>>


I don't fully understand this : can't multiply sequence by non-int of type 'numpy.float64'

Can you please tell me how to change my script so that I can model it ?
