hi, in python, i got a massive signals with random data types need to initialize, below is a sample:

import rclpy

from std_msgs.msg import Float32
from std_msgs.msg import Int8

x = Float32()
y = Int8()


x.data = 0.0
y.data = 0

where the initials of = 0.0 or = 0 depends on data types, when i coding i need to check type manually first then decide to write 0.0 or 0, is quite not smart.

if i directly make them all like

x.data = 0
y.data = 0

it's easy to coding but i got error AssertionError: The 'data' field must be of type 'int'

is there a way like auto in cpp to make this case easier to coding?

like auto_type() below

import rclpy

from std_msgs.msg import Float32
from std_msgs.msg import Int8

x = Float32()
y = Int8()


x.data = auto_type(0)
y.data = auto_type(0)

x.data # = 0
y.data # = 0
