This may be due to changes regarding DLL dependency resolution in 3.8. If so, you can find the missing DLL using Process Monitor, configured to monitor file access in python.exe and pythonw.exe. Add the DLL's directory to the search path via os.add_dll_directory [1] before importing from pyodbc. The developers of pyodbc should be directed to the porting notes for the DLL search requirements in 3.8 [2]. The interpreter and ctypes no longer support the old DLL search path that includes the working directory and PATH [3].
