Re: [libvirt] [PATCH 11/22] WmiClass: Don't share "versions" between instances

Lists in Python are mutable and when used as a default value of a parameter for class constructor, its value will be shared between all class instances. Example: class Test: def __init__(self, mylist=[]): self.mylist = mylist A = Test() B = Test() A.mylist.append("mylist from instance A") print(B.mylist) # Will print ['mylist from instance A'] Signed-off-by: Radostin Stoyanov <rstoyanov1(a)gmail.com&gt; --- src/hyperv/hyperv_wmi_generator.py | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-)
