Its not normally very helpful since in Python the same function can have 
many names:

def F(x):
    return x*x

a = F
b = F
c - lambda y: F(y)

print F(1), a(2), b(3), c(4)

Now, why would knowing whether the caller used F,a or b
to call the same function object help? And what do you
do in the case of c()? Do you return 'c' or 'F'?

Maybe you could use it to tell you the context from
which they were calling? But in that case there are
usually better, more reliable, techniques
  - like examining the stackframe.
