I have never used a call to "locals()" in my code. Can you show me a
use case where it is valuable and Pythonic?
def print_item(item):
description = textwrap.fill(item.description, 40)
short = item.description.split('\n', 1)[0]
code = str(item.id).zfill(6)
print "%(code)s %(short)s\n%(description)s\n" % locals()
Transferring arguments:
def foo(some, long, list, of, arguments):
additional = 5
return other(**locals())
Defining properties:
class ColourThing(object):
@apply
def rgb():
def fset(self, rgb):
self.r, self.g, self.b = rgb
def fget(self):
return (self.r, self.g, self.b)
return property(**locals())
