Python check variable against multiple lists

So I have 3 lists of data, I need to test if any of the data I get from the json response is in any of the lists, I'm probably being stupid about it but I'm trying to learn and can't seem to get it to work right.

list1 = ['a', 'b', 'c']
list2 = ['a1', 'b1', 'c1']
list2 = ['a2', 'b2', 'c2']

#block of code...
#block of code...

content = json.loads(response.read().decode('utf8'))
data = content
for x in data:
   #if x['name'] in list1: #This works fine the line below does not.
   if x['name'] in (list1, list2, list3):
   print("something")

As a pythinc way for such tasks you can use any for simulating the OR operand and all for and operand.

So her you can use a generator expression within any() :

if any(x['name'] in i for i in (list1, list2, list3))

What about concatenating the lists?

if x['name'] in [list1 + list2 + list3]:

I suggest something simple and straight-forward:

if (x['name'] in list1 or 
    x['name'] in list2 or 
    x['name'] in list3):
    ...
