i have a problem:

I need to implement a function in python which prints a skalar multiple of an argument - the argument is a function itself which has the signature:

```
def innerF(a,b):
    return x

```

The skalar multiplier is a constant within the function - e.g.

`return 55 * x`

Now comes the part i dont seem to get:
The call Sytanx is required to be:

`print( outerF(innerF)(a,b))`

So in summary

```
def innerF(a,b):
    return a + b

def outerF( #What goes here? ):
    return 55* #How two call the innerF?

print(outerF(innerF)(a,b))

```

What i know so far:

* I can pass the innerF an the a,b as seperate arguments to outerF like

def outerF(innerF,a,b):
return 53\* innerF(a,b)

What i dont get:

The signature of the outerF call with `innerF(outerF)(a,b)` is completly unknow to me. Also i could not find refernce.

Thank you very much in advance!
