You clear sys.modules, which apparently CPython uses in its normal function.
Python 3.2.5 (default, Oct 2 2013, 22:58:11)
d = {}
import sys
d = sys.modules
type(d)
<class 'dict'>
dir(d)
['__class__', '__contains__', '__delattr__', '__delitem__', '__doc__',
'__eq__', '__format__', '__ge__', '__getattribute__', '__getitem__',
'__gt__', '__hash__', '__init__', '__iter__', '__le__', '__len__',
'__lt__', '__ne__', '__new__', '__reduce__', '__reduce_ex__',
'__repr__', '__setattr__', '__setitem__', '__sizeof__', '__str__',
'__subclasshook__', 'clear', 'copy', 'fromkeys', 'get', 'items', 'keys',
'pop', 'popitem', 'setdefault', 'update', 'values']
dir(d) is the contents of d.__dict__, not d itself, so the above is not
what you clear. Just type d to see what is cleared.
d.clear()
Traceback (most recent call last):dir(
File "<stdin>", line 1, in <module>
There is no code line because the exception in in C code. 3.4.2 gives
more info: RuntimeError: lost builtins module. Do upgrade if you can.
In Idle, this executes 'ok', without an exception, because it clears
sys.modules in the user process, not the Idle process.
d
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
However, this throws the user process into a loop, literally.
