将A类对象的每个字段复制到列表中classB对象的每个字段中

class A:
    def __init__(self, field1, field2):
        self.field1 = field1
        self.field2 = field2

class B:
    def __init__(self, field1, field2):
        self.field1 = field1
        self.field2 = field2

def copy_fields(a_objects):
    b_objects = []
    for a_obj in a_objects:
        b_obj = B(a_obj.field1, a_obj.field2)
        b_objects.append(b_obj)
    return b_objects

# 示例用法
a_objects = [A("value1", "value2"), A("value3", "value4")]
b_objects = copy_fields(a_objects)
for b_obj in b_objects:
    print(b_obj.field1, b_obj.field2)
