如何从参数调用python对象？

def process_data(data):
    # 对传入的data对象进行处理
    # ...

my_data = [1, 2, 3, 4, 5]
process_data(my_data)

def process_data(data=None):
    # 对传入的data对象进行处理
    # ...

my_data = [1, 2, 3, 4, 5]
process_data(data=my_data)

def process_data(*args):
    for data in args:
        # 对传入的data对象进行处理
        # ...

my_data1 = [1, 2, 3]
my_data2 = [4, 5, 6]
process_data(my_data1, my_data2)

def process_data(**kwargs):
    for key, value in kwargs.items():
        # 对传入的value对象进行处理
        # ...

my_data1 = [1, 2, 3]
my_data2 = [4, 5, 6]
process_data(data1=my_data1, data2=my_data2)
