Why x+=1 doesn't return x value instead of an object

[Siddhharth Choudhary]

I want to know why x+=1 does not return the value of the variable. It would be 
great if It has returned the value of the variable instead of an object. It 
will increase the beauty of python.
For instance,
              x = 5
              x+=1
              print(x)   = 6
If x+=1 had returned the value instead of object
              x = 5
              print(x+=1)   = 6
which is not possible?
