I want to update my similar name atributes but I get an error:

```
Traceback (most recent call last):
  File "python", line 12, in <module>
NameError: name 'name_0_' is not defined

```

Here is my code:

```
class Test:
    name_0_1 = 0 
    name_0_2 = 0   
    name_0_3 = 0 
    name_0_4 = 0

my_object = Test()
my_list_value = range(1,8)

for i in my_list_value:
  print(setattr(my_object, name_0_ + str(i), i))

```
