Ans : A function, which can accept other function as an arguments and return function to the caller is known as higher order fi=unction. See the example below.
|
def doOperation(a,b): def operation(x): return (a+x) *(b+x) return operation |
Here, doOperation function take two arguments a and b as input and return operation function as an output. So you call the function as below.
|
result=doOperation(5,10) result(10) |
It will give output as below
(5+10)*(10+10)=(15)*(20)=300
