Calling a service within a Python script

[lpmrz]

Hello,

Let's say I want to call a service within a Python script, namely /uav1/control_manager/start_trajectory_tracking. How can I achieve this?

Thank you very much.

edit: I tried the solution below but failed. I didn't understand why it needs an argument since when I check if it needs an argument it returns false.

edit#2 : I solved my problem.

Hello, this is a standard ROS and Python question. Please, google first, then search for examples, and then ask questions. Calling service requires setting a service client first.
