Question #197489 on Yade changed:
https://answers.launchpad.net/yade/+question/197489

Jan Stránský proposed the following answer:
Hello Nishith,

the first solution is to use

c1= O.bodies.appendClumped (spheres) # without braces around speheres

then you will have problems on the next line, as c1 is tuple of int and
list of ints.. I have never used makeClumpCloud, so I dont know how to
fix it, hopefully somebody else will help you :-)

Jan
