Summary0001394: Python imports used on functions output warnings on Debian|Ubuntu installations
DescriptionOn Debian|Ubuntu the installation process execute /usr/lib/freecad/Mod/Ship/simRun/Simulation.py which outputs some warning due to using import on functions.

 SyntaxWarning: import * only allowed at module level
  def run(self):

https://github.com/FreeCAD/FreeCAD_sf_master/blob/master/src/Mod/Ship/simRun/Simulation.py#L92

According to http://stackoverflow.com/questions/3571514/python-why-should-from-module-import-be-prohibited this restriction was introduced in Python 2.1, as a consequence of the "Nested Scopes" feature (PEP 227), quoting:

One side effect of the change is that the from module import * and exec statements have been made illegal inside a function scope under certain conditions. The Python reference manual has said all along that from module import * is only legal at the top level of a module, but the CPython interpreter has never enforced this before. As part of the implementation of nested scopes, the compiler which turns Python source into bytecodes has to generate different code to access variables in a containing scope. from module import * and exec make it impossible for the compiler to figure this out, because they add names to the local namespace that are unknowable at compile time. Therefore, if a function contains function definitions or lambda expressions with free variables, the compiler will flag this by raising a SyntaxError exception.

Steps To ReproduceI'm not sure in which way Freecad is called during the configuration phase. However it seems that at least the /usr/lib/freecad/Mod/Ship/simRun/Simulation.py is executed.

the install debian/ubuntu install scripts try to compile .py to .pyc files. This makes some sense as the ordinary user won't have sufficient rights to compile them at the time of the first run.
