[New-bugs-announce] [issue6862] exec(), locals() and local variable access

[john zeng]

New submission from john zeng <ooev at 163.com>:

Can you help me understand why variable `u' is not accessible after 
exec()? Is this sort of a late binding issue?

def test(v1):
    print(v1)
    print("Before exec(): " + str(locals()))
    exec(v1)
    print("After  exec(): " + str(locals()))
#   This fails:
#    print(u)
#   This is workaround:
    en = locals()['u']
    print(en)

v1="u=4"
test(v1)
