N = 10

# input the number of columns

M = 10

# initializing the matrix

res = [ [ i*j for i in range(N) ] for j in range(M) ]
clash(i,j)=0

# printing in multiple lines

print("Multiline representation")
for i in range(N):
   for j in range(M):
          #matrix.append(["0"]*100)
      print(res[i][j] ,end =" ")
   print("")

存在一个错误，显示无法在clash（i，j）=0时分配到函数调用。因此，我真的需要帮助！
