There are plenty of tools available for converting python script into executable. For example, check out:
For Python 2, I used to prefer py2exe. It is a neat tool that does the trick by making a stand alone executable from python script. The one problem I faced was, py2exe used to support only python 2! Then I moved on to PyInstaller. Now the good thing is, py2exe now provides support to Python 3 as well! I might share my py2exe experience as well but, that will be in another article.
This article is all about PyInstaller! It is a handy tool specially when you can create an .exe file for windows with only one command! Although I prefer Linux, I had to create executable for windows all the time targeting various Windows distributions (Yes, It was Clients’ requirement)
Lets explore the process of creating executable using PyInstaller.
Hassle free installation, all you have to do is to run the following command (if you have already installed python) and that’s it!
pip install pyinstaller
Note: If you are working on Windows. You might need to install PyWin32 as well! Download it from here:
And, If you need additional help, you can always head right to the Official Documentation of PyInstaller:
If you are using different package management tool such as conda (forAnaconda) then you will have to use the following commands instead:
conda install -c conda-forge pyinstaller conda install -c anaconda pywin32
Please, find suitable installation documentation for your package management tool for more details.
Now that, you have installed PyInstaller all you have to do is find the python script that you want to convert to an executable. Just navigate to your python script directory. Now, open up your Terminal/Command Prompt in the script directory and, test your python script:
Make sure, the script work as expected. Now, The command I prefer for compiling the script into executable is the following one!
Run the command:
pyinstaller --onefile <your_script_name>.py
This will create a standalone executable in the
dist directory of your script folder. Don’t worry, if the folder doesn’t exist it will create one automatically.
Notice that we passed an argument
--onefile. This argument tells PyInstaller to create only one file. If you don’t specify this, the libraries will be distributed as separate files along with the executable.
The format/extension of the executable will depend on which operating system you used for compilation. For example, if you run the PyInstaller command on windows the executable file will be .exe. If you run it on Linux the extension will depend on the distribution you are using.
You can only create executable for your Operating system, i.e. the Operating system you used to compile the executable.
For example, It is not possible to create a Windows executable (.exe) by directly running a Pyinstaller command on a Linux Distribution and vice versa. (If you know a way to do it, feel free to comment)
What you can do is run Virtualbox or similar application to run the OS virtually and, create executable in that virtual os and export it later. Also, Wine works as well! (Though, I didn’t try it myself)
If your python script depends on additional executables say for example, phantomjs or chromedriver. You may have to put these executable in the same directory of your executable!
For these types of dependencies, when I’m working on Windows Platform I usually package them using NSIS. The procedure is like below (Assuming NSIS already installed):
- Create a ZIP of all the necessary files i.e script’s executable, dependencies, read me etc.
- run NSIS
- Click on the
make installer from zip archiveoption.
- Select the zip file that you’ve created earlier.
- Provide a name and create the Installer.exe/Setup.exe file.
This executable is basically an extractor that extracts all the necessary file in a directory. Cool!
