Action if selection has item or not

import maya.cmds as cmds
target = cmds.ls(sl=True)
if target:
    print('yes')
else:
    print('no')

Adding objects

To a curve

from random import uniform
delta = 1.0/10
for n in range(40):
    if uniform(0,1) > 0.5:
        x,y,z = cmds.pointOnCurve( 'curve44', pr=(delta * n), p=True )
        cmds.sphere(r=uniform(0.01, 0.04))
        cmds.move(x,y,z)
