[Python] Wrap class method with argument(s) only once

There are two classes and I want to wrap item.foo method only once, to prevent cache = {param1: 'param_value'} being reinited

class Foo:
_count = 0

def foo(self, param2):
self._count += param2


class Bar:
_collection = [Foo(), Foo(), Foo()]

def bar(self, param1, param2):
for item in self._collection:
wrapped_function = wrapper(item.foo, param1)
wrapped_function(param2)


def wrapper(func, param1):
# some database call or whatever
cache = {param1: 'param_value'}

def _wrapper(*args, **kwargs):
# access value to read
print(cache[param1])
return func(*args, **kwargs)
return _wrapper


bar = Bar()
bar.bar(1, 2)


It can be achieved if wrapper had no params in it and was used as a simple decorator, but I have to pass a param1 in it, though it's always the same. I also can save cache = {param1: 'param_value'} before the cycle in def bar and pass it as the parameter, but I was wondering if there any other way to accomplish it.

Kinda can't wrap my head around it(pun intended)
