Summary: weird behavior when assigning locals() to a variable
Initial Comment:
Tried this on Python 2.3.3, under Redhat Linux
Enterprise 3, and on Python 2.3.5, under MacOS X
10.4.3. Don't have access to 2.4 anywhere, so I can't
test it, but I took a look at the bug queue and can't
find any reference to this problem.
The following function yields a KeyError when run:
def foo():
b = locals()
c = 5
print b["c"]
The following function does not:
def foo():
b = locals()
c = 5
locals()
print b["c"]
There's no typo there. After referencing locals()
again, without updating the value of b, the printout works.
Note that b and locals(), as I believe is intended, are
identical:
def foo():
b = locals()
c = 5
print id(b)
print b.has_key()
print id(locals())
print b.has_key()
yields, when run:
>>> foo()
285984
False
285984
True
This has GOT to be a bug.
