Divide a list by elements of another list

I want to divide a list error_variance_vector by an element in another list sigma_square1, such that it gives corresponding W element (w_i).

error_variance_vector=[]
for i in range(0,len(bpm_indexes)):
    n = 10
    error_variance_vector.append(n)

error_variance_vector = [10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10] 

sigma_square = [i**2 for i in error_variance_vector]

Here’s my attempt:

w = []
for sigma_square1 in sigma_square:
    w.append(error_variance_vector / sigma_square1)
    
W = np.diag(w)
print(W)

but I got an error message:

TypeError: unsupported operand type(s) for /: 'list' and 'int'

Answer

This should work:

w = [e/s for e,s in zip(error_variance_vector,sigma_square)]
