Nine Rules for Scheduling Events

How would Slipmat’s @ scheduler work when applying various Python methodologies?

To celebrate the release of my friend Sarah MacLean’s new book, Nine Rules to Break When Romancing a Rake, here are 9 rules for scheduling events. Each of the following examples produce the exact same result:

1. Individual Events

@0 foo()
@1 foo()
@2 foo()
@3 foo()

2. List

@[0, 1, 2, 3] foo()

3. Identifier

t = [0, 1, 2, 3]
@t foo()

4. List Comprehension

@[i for i in range(0, 4)] foo()

5. Loop

for i in range(0, 4):
    @i foo()    

6. Function

def bar():
    @0 foo()
    @1 foo()
    @2 foo()
    @3 foo()
    
bar()

7. Nested

foo()
1:
    foo()
    1:
        foo()
        1:
            foo()

8. Item Iteration

items = (0, 1, 2, 3)
@[i for i in items] foo()

9. Map

def bar(x): return x
@(map(bar, range(0, 4)) foo()
