&gt; The math module build-in python use c modules , according to
&gt; Python-3.7.2\setup.py , the math module information as below:
&gt; shared_math = 'Modules/_math.o'
&gt; # complex math library functions

&gt; Can you tell me how to import the math module on windows via
&gt; pyqtdeploy? thank you!

Enable the module in the pyqtdeploy GUI.

&gt; 
&gt; I have no idea what that DLL is. pyqtdeploy supports the standard 
&gt; Python
&gt; math module. If you do not have lots of experience building and
&gt; debugging C++ code on Windows then please use something else.
