if I turn a python script into an exe does it need python to run code example

Example 1: how to run a .exe through python

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

Example 2: can you release a python program to an exe file

# In the command line, install pyinstaller
python -m pip install pyinstaller

# You might need to add pyinstaller to path. You can do that
# by adding the "scripts" folder in your python installation to path
pyinstaller yourprogram.py
