code for making an exe file for python

pip install pyinstaller

cd PathOfFile

pyinstaller --onefile -w ScriptName.py

(note that if you are using -w then your python file has to be an application and the file will be inside the "dist" folder)

pip install pyinstaller

pip install pyinstaller

cd FullPathOfFile in cmd console
pyinstaller --onefile pythonScriptName.py
# a .exe file is created in the FullPathOfFile\dist

import os
os.startfile("C:\Documents and Settings\flow_model\flow.exe")
