How can I install package with my debian package?

Question

Hello I have create a debian package but my problem is this package needs to have a python library so I thought I have to put inside the preinst file :

sudo apt-get install ...

So I tried but when I tried I get "Could not get lock ..."

I guess I can't install in the same time my package and also the python library.

But I noticed when I did a sudo apt-get install sometimes I installed other packages not only the package that I install. So I think there is a solution to my problem but I don't know it.

I try to a create a bash file which install the library python then I can install the package but I have two files...

Is there a solution to install in my debian file the package and the python library ?

Thank you very much !

I precise I work on Ubuntu 16.04
