Using a dictionary to select function to execute

Question

I am trying to use functional programming to create a dictionary containing a key and a function to execute:

myDict={}
myItems=(\"P1\",\"P2\",\"P3\",....\"         


        

Answer 1

Simplify, simplify, simplify + DRY:

tasks = {}
task = lambda f: tasks.setdefault(f.__name__, f)

@task
def p1():
    whatever

@task
def p2():
    whatever

def my_main(key):
    tasks[key]()
