Functions as Objects

def add1(n):
    return n+1

L1 = [ random.randint(1,30) for i in range(5) ]

L2 = []
for val in L1:
    newval = add1(val)
    L2.append(newval)

print(L1)
print(L2)

def apply_func(func, data):
    result = []
    for val in data:
        newval = func(val)
        result.append(newval)
    return result

L2 = apply_func(add1, L1)
print(L2)

Q Create three more functions, add2, add3, and add4 and then create a list called funcs whose elements are the four functions add1 through add4.

# YOUR CODE HERE
raise NotImplementedError()

Q Suppose you are given a list of numbers L3 whose length is the same as funcs. Write code to generate list L4 whose values come from applying the corresponding function from funcs to its correspondent in L3. Bonus to do this with a list comprehension.

L3 = [5, 9, 2, 7]
# YOUR CODE HERE
raise NotImplementedError()
print(L4)
