I have searched in google or some other search engines, i got some packages “pyinstaller” and “pyuic” but in that examples only .py files are converting into .exe file. But i have another two .ui files which i want to include into the .exe along with .py files.
What do you mean by a “.ui file”? What libraries, frameworks etc. are you already using?
In software development, a “.ui” file typically refers to a User Interface (UI) file. UI files are commonly used in graphical user interface (GUI) frameworks and tools to define the layout and structure of a user interface. I am using PyQt5 library for GUI development and it’s functionality, Ya i am using this libraries and frameworks.
Can’t be all THAT common; I’ve never used them myself, and this is the first time I can recall hearing about them. There are quite a few ways of having external files that define your GUI, and far more ways of defining a GUI that don’t use external files at all. 
Thank you chris.
Qt Designer creates a user interface layout in a “.ui” XML file. For PyQt or PySide, a “.ui” file can either be converted to a Python class or loaded at runtime.
You could try asking on the pyqt mailing list fir help.
There are very knowledgeable people that are helpful there.

I use qt a lot, but do not use .ui files at all as i find it is easy to build the ui in python.
Thanks. My point was, though, that no matter how “obvious” you think this is, it’s worth including the context.
