It is possible to get values from thread , while thread is executing , but not yet complete?
if it is possible then how can I realise it in python?

with hope to solution

In the past I have used global variables to pass messages to/from threads. In order to avoid disaster I only allow one thread to write to any given variable.

There are operating-system-specific message passing primitives you can also use, but then they tend to be operating system specific, or relatively heavyweight like networking.

In this case global variables are not suitable.
Maybe do you know another solution?
the basic problem is : I have a webservice and I need to get results from webservice , when it is not yet finished..

Package the results you need in a class designed for that purpose.
Each thread you start, pass a unique class instance.
Have the thread routine modify fields in the class instance as appropriate.
