Return function that modifies the value of the input function

2024/11/18 9:26:20

How can I make a function that is given a function as input and returns a function with the value tripled. Here is some pseudo code for what I'm looking for. Concrete examples in Python or Scala would be appreciated.

def f(int x):return x ** 2def tipleFunc(Function g)return 3 * gFunction newFunc = tripleFunc(f)
print newFunc(5)

Answer

def f(x):return x ** 2def tripleFunc(g):return lambda *args: 3 * g(*args)newFunc = tripleFunc(f)
print newFunc(5)
