$$What is wrong with my code? I keep getting error that says operands could not be broadcast together with shapes

Part $1$: Matrix Operations

$1\mathrm{.}1[3$ pt$]$ Write a function called operations that takes three inputs: a real number $c($a float$)$ and two matrices A and $B($numpy arrays$).$ It should return a dictionary that has seven keyvalue pairs:

shape: the shape of $A($as a tuple$)$

scale: A scaled by $c($as a numpy array$)$

sum: A plus $B($as a numpy array$)$

difference: A minus $B($as a numpy array$)$

elementwise$\_$multiplication: elementwise multiplication between A and $B($as a numpy array$)$

matrix$\_$multiplication: matrix multiplication between A and $B($as a numpy array$)$

transpose: A transposed $($as a numpy array$)$

If the shapes of A and $B$ are such that a certain key's value is not mathematically possible, then make its value the string "not possible".

import numpy as np

def operations $(c,A,B$ :

result $=\{\}$

result $[\text{'}$shape $\text{'}]=$A$.$ shape

if A$.$ shape$[1]==$ B$.$ shape$[0]$:

result$[\text{'}$scale$\text{'}]=C**A$

result$[\text{'}$sum$\text{'}]=A+B$

result $[\text{'}$difference$\text{'}]=A-B$

result$[\text{'}$elementwise$\_$multiplication'$]=A**B$

result $[\text{'}$matrix$\_$multiplication'$]=np*dot(A,B)$

result $[\text{'}$transpose$\text{'}]=$A$.$transpose$()$

else:

result$[\text{'}$scale$\text{'}]=$ 'not possible'

result$[\text{'}$sum$\text{'}]=$'not possible'

result$[\text{'}$difference$\text{'}]=$ 'not possible'

result$[\text{'}$elementwise$\_$multiplication'$]=$'not possible'

result$[\text{'}$matrix$\_$multiplication'$]=$ 'not possible'

result$[\text{'}$transpose$\text{'}]=$'not possible'

return result
