How to Convert a Python .py Script to an .exe File Using cx_Freeze?

Converting Python .py to .exe

Introduction

Converting a Python script to an executable (.exe) allows it to run independently of a Python interpreter. To achieve this in Python 3.6, several methods are available, but they can present challenges. This article addresses those challenges and provides a comprehensive guide for converting a Python script to .exe using cx_Freeze.

Method:

1. Install Python 3.6: Ensure you have Python 3.6 installed on your system.
2. Install cx_Freeze: Use pip to install cx_Freeze:

pip install cx_Freeze

3. Install idna: Some modules may require additional dependencies. Install idna:

pip install idna

4. Create Python Script: Write a Python script with the extension .py. For example, let's name it "myfirstprog.py."
5. Create setup.py Script: Create a new Python file named "setup.py" in the same directory as your script.
6. Add Code to setup.py: Paste the following code into setup.py:

from cx_Freeze import setup, Executable

base = None

executables = [Executable("myfirstprog.py", base=base)]

packages = ["idna"]
options = {
    'build_exe': {
        'packages':packages,
    },
}

setup(
    name = "<any name>",
    options = options,
    version = "<any number>",
    description = '<any description>',
    executables = executables
)

7. Open Command Prompt: Shift-right-click in the directory to open a command prompt window.
8. Run Command: Type the following command:

python setup.py build

9. Locate .exe File: If successful, a "build" folder will be created. Within that folder, your .exe application will be located.

Additional Notes:

• Modify setup.py: Update the name, version, and description fields in setup.py to match your application.
• Include Imported Packages: Add any imported packages in your Python script to the "packages" list in setup.py.
• Install Dependencies: Ensure all required dependencies are installed before running "python setup.py build."

By following these steps, you can easily convert a Python script to an executable using cx_Freeze in Python 3.6.
