Hey, guys, am I the only one here who can't even guess what
this code does? When did Python become so obscure?
Thankfully it hasn't. The most Pythonic way to pass around a code
block is still to use a function.
"Most Pythonic" doesn't mean better, unfortunately.
For instance, assume that you want to write a function that accepts a
dictionary of callbacks:
func(some_args, callbacks)
Pythonic way
------------
def when_odd(n):
pass
def when_prime(n):
pass
def before_check():
pass
def after_check():
pass
func(some_args, {'when_odd' : when_odd,
'when_prime' : when_prime,
'before_check' : before_check,
'after_check' : after_check})
def when_prime(n):
pass
def when_perfect(n):
pass
def before_reduction()
pass
def after_reduction():
pass
func(some_args, {'when_prime' : when_prime,
'when_perfect' : when_perfect,
'before_reduction' : before_reduction,
'after_reduction' : after_reduction})
My way
------
with func(some_args) << ':dict':
with when_odd as 'n':
pass
with when_prime as 'n':
pass
with before_check as '':
pass
with after_check as '':
pass
with func(some_args) << ':dict':
with when_prime as 'n':
pass
with when_perfect as 'n':
pass
with before_reduction as '':
pass
with after_reduction as '':
pass
