    2. pip install idna
  • Create a new python file named in the current directory of your script and put the following code in it:
from cx_Freeze import setup, Executable
import os
os.environ['TCL_LIBRARY'] = r'C:\\ProgramData\\Anaconda3\\envs\\ch2_venv\\tcl\\tcl8.6'
os.environ['TK_LIBRARY'] = r'C:\\ProgramData\\Anaconda3\\envs\\ch2_venv\\tcl\\tk8.6'

options = {
    'build_exe': {    

    name = "my_name",
    options = options,
    version = "0.1",
    description = 'My discription',
    executables = executables

I also had to add pyodbc in the packages list as cx_Freeze was giving me error otherwise.
    • Note: in the above code snippet for, put the filename for file for which you want the exe here executables (I am having
    • Note: in the above code snippet for, packages lists all the imported packages in your python code
  • now, in the terminal, type:python build
