#in another script you would import test_module (without the .py)
#you would then call the functions you defined in your module one by one
#example (in a new script)

import test_module as tm  #imports this module and all the functions it contains

tm.hello_world()  #runs a function included in the module
import test_module as tm

tm.hello_world(
)  #the period allows to get the members of tm, thus we are calling the
#hello_world function
