Not sure I hate it, either. ;)
Slightly more sophisticated code:
<code>
class NameSpace(object):
def __init__(self, current_globals):
self.globals = current_globals
self.saved_globals = current_globals.copy()
def __enter__(self):
return self
def __exit__(self, *args):
new_items = []
for key, value in self.globals.items():
if (key not in self.saved_globals and value is not self
or key in self.saved_globals
and value != self.saved_globals[key]):
new_items.append((key, value))
for key, value in new_items:
setattr(self, key, value)
del self.globals[key]
self.globals.update(self.saved_globals)
if __name__ == '__main__':
x = 'inside main!'
with NameSpace(globals()) as a:
x = 'inside a?'
def fn1():
print(a.x)
with NameSpace(globals()) as b:
x = 'inside b?'
def fn1():
print(b.x)
def fn2():
print('hello!')
b.fn1()
y = 'still inside main'
a.fn1()
b.fn1()
print(x)
print(y)
