How can I test a ros package version from python script

It appears there's a mechanism to fetch package version via ROS, available in CLI

e.g. rosversion nano_light

0.0.0

where 0.0.0 is saved in the ROS package XML

is there an API to get this data from rospy?

Here's one way to do it in Python, using rospkg:

import rospkg

r = rospkg.RosPack()
m = r.get_manifest('my_package')
print(m.version)

# Output: '1.3.0'
