```
s=[[2,3],[4,5]]
t=[[1,2,3],[1,2,0]]
l1=[]
def multiply_matrices(a,b):
for i in range(len(a)):
l2=[]
for j in range(len(b[0])):
x=a[i][0] * b[0][j]
y=a[i][1] * b[1][j]
m=x+y
l2.append(x)
l1.append(l2)
return(l1)
multiply_matrices(s,t)
```

i have submitted the matrix assignment and in that in the last question i have done it 2 times ,this above code is the first one and it is incorrect ,so how to correct it using only 2 for loops
