Creating an executable file of a Python script can be a very helpful tool for people who frequently use Python. This article will cover how to create an executable file of a Python script using the PyInstaller package, along with the necessary steps for setting up Python and running a Python script.
Adding Python to Windows Path
Before we can start with the process of creating an executable file, we need to make sure that Python is added to our Windows Path.
Adding Python to Windows Path allows us to type ‘python’ in the command prompt and directly execute Python code without having to browse to the Python installation folder. To add Python to Windows Path, follow these steps:
1.
Open the Start menu and search for “Environment Variables”. 2.
Click on “Edit the system environment variables.”
3. In the System Properties window, click on the “Environment Variables” button.
4. Under “System Variables”, search for “Path” and click on “Edit”.
5. Click on the “New” button and enter the path to your Python installation folder.
The typical path is “C:Pythonxx” (where xx is the version number, e.g. 36, 37, 38). With this step completed, we can now move on to installing the PyInstaller package.
Installing the PyInstaller Package
The PyInstaller package can be easily installed using pip. Pip is a package manager for Python that allows us to easily manage and install Python packages.
To install PyInstaller, follow these steps:
1. Open a command prompt.
2. Type “pip install pyinstaller” and press Enter.
3. Wait for the installation to complete.
This should only take a few seconds. With PyInstaller installed, we can now move on to writing our Python script.
Saving the
Python Script
For the purposes of this article, we will use a simple Python script that displays text when a button is clicked. To write the Python script, open a text editor such as Notepad or Sublime Text and type the following code:
“`python
from tkinter import *
root = Tk()
label = Label(root, text=”Hello, world!”)
label.pack()
button = Button(root, text=”Click me!”)
button.pack()
root.mainloop()
“`
Save the file as “hello.py” in a folder of your choice.
Creating the Executable using PyInstaller
Now that we have our Python script, we can create an executable for it using PyInstaller. To do this, follow these steps:
1.
Open a command prompt. 2.
Navigate to the folder where your Python script is saved. 3.
Type the command “pyinstaller hello.py” and press Enter. 4.
Wait for PyInstaller to create the executable. This will create a new folder called “dist” in the same directory as your Python script.
Running the Executable
To run the executable, navigate to the “dist” folder and double-click on “hello.exe”. If the executable does not run, you may need to install the Visual C++ Redistributable for Visual Studio.
This can be downloaded from the Microsoft website.
Python Script
As promised, we will provide a simple Python script example that displays text when a button is clicked. This can be a helpful introduction for those new to Python.
To write the Python script, open a text editor such as Notepad or Sublime Text and type the following code:
“`python
from tkinter import *
root = Tk()
label = Label(root, text=”Hello, world!”)
label.pack()
button = Button(root, text=”Click me!”)
button.pack()
root.mainloop()
“`
Save the file as “hello.py” in a folder of your choice. Then, follow the steps outlined in the previous section to create an executable for the script.
Folder Location
When writing Python scripts, it’s important to save them in a location that is easily accessible and organized. This ensures that we can quickly find our scripts when we need them, and makes it easier for us to manage our projects.
We recommend creating a folder specifically for your Python scripts. This can be named something like “
Python Scripts” or “Projects”.
Save all of your Python scripts in this folder, and organize them by project or by topic.
Conclusion
Creating an executable file of a Python script can be a huge time-saver for anyone who frequently uses Python. By following the steps outlined in this article, you can easily create an executable for your Python script using PyInstaller.
Remember to save your Python scripts in a well-organized folder for easy access. With these tips, you’ll be well on your way to becoming a Python expert!

By adding Python to the Windows Path, we can easily access Python commands from any directory in our computer, making it easier to work on large projects or when we need to run Python scripts from different directories.
PyInstaller can be a powerful tool when we need to distribute our Python scripts to others who may not have Python installed on their computer. By creating standalone executable files, we can ensure that our scripts can be run on any Windows computer without requiring the recipient to install Python or any dependencies.
Saving the
Python Script
Saving a Python script is an essential step in the development process. Saving the script ensures that our work is saved, and we can easily return to it later.
Additionally, saving the script with a proper naming convention helps us organize our work more efficiently. In this section, we will discuss the importance of saving Python scripts and the proper naming convention for Python scripts.
Importance of Saving
Python Script
Saving a Python script is important because it provides us with a backup of our work. In case of any computer or program crashes or accidents, we can quickly recover our work and continue from where we left off.
Moreover, when saving the script, we can track the changes made throughout the development process and revert to previous versions if we need to. Proper Naming Convention for
Python Script
Proper naming convention for Python scripts is essential for good organization and readability.
Using a consistent naming convention makes it easy to find scripts later on. Here are some guidelines for choosing a naming convention for Python scripts:
– Use a descriptive name that indicates the purpose or functionality of the script.
– Use all lower case letters, and separate words using underscores (_) rather than spaces. – Begin the file name with a letter, not a number.
– End the file name with the file extension “.py”, which indicates that it is a Python script. Following a proper naming convention can help us quickly identify our scripts and keep our work organized.
Creating the Executable using PyInstaller
PyInstaller is a widely used package in the Python community that allows us to create standalone executables from Python scripts. With PyInstaller, we can quickly and easily package our Python scripts into a single executable file that can be run on any computer without requiring any Python installations or dependencies.
In this section, we will discuss how to use the command prompt to create an executable and the details of the PyInstaller templates.
Using Command Prompt to Create Executable
To create an executable using PyInstaller, we need to follow the steps listed below:
1. Open a command prompt and navigate to the directory where the Python script is saved.
2. Type the command “pyinstaller scriptname.py” and press Enter.
3. Wait for the process to complete.
Once the process is finished, the executable will be saved in a “dist” folder in the same directory as the Python script. PyInstaller automatically scans our Python script and identifies the necessary dependencies to package into the executable file.
The resulting executable file is self-contained and does not require any prior installations of Python or its dependencies.
Details of PyInstaller Template
PyInstaller also provides templates that can be customized to create the executable file according to our requirements. These templates are based on the bootloader used to load the executable when it is run.
Some of the available PyInstaller templates include one-file, one-directory, multi-file, and console-based templates. Using a one-file template creates a single executable file that contains everything needed to run the application.
This template is useful when we need to distribute a single file to users without any additional dependencies. Similarly, using a one-directory template creates an executable file along with its dependencies in a single directory.
This template is helpful when we need to distribute a complete application with multiple files and resources. The multi-file template creates an executable that contains multiple source files and libraries required to run the application.
This template is useful when we need to package an entire application with multiple dependent files. Finally, the console-based template specifies that the application runs in a console window rather than a GUI.
This is useful when we need to interact with the user via command-line input.
Conclusion
Saving Python scripts with proper naming conventions help us organize our work better. Creating executables using PyInstaller provides developers with a convenient way to distribute their Python scripts to users without requiring the installation of additional dependencies.
PyInstaller templates provide developers with flexible options to customize the packaging of executables according to their requirements. Follow these guidelines to create and distribute your Python scripts effectively and efficiently.
Running the Executable
Once we have created an executable using PyInstaller, we can run it on any computer without requiring any prior installations of Python or its dependencies. However, there are some details we need to keep in mind when running the executable.
In this section, we will discuss the details of executing the executable and testing it.
Details of Executing the Executable
To execute the executable, we need to navigate to the “dist” folder where the executable is saved and double-click on the “.exe” file. However, there are some details we need to keep in mind when running the executable.
Sometimes, when we try to run the executable, we may encounter an error message that says “The program can’t start because VCRUNTIME140.dll is missing from your computer.” This error message appears when the Visual C++ Redistributable is not installed on the computer. To resolve this issue, we need to download and install the Visual C++ Redistributable from the Microsoft website before running the executable.
Testing the Executable
Testing the executable is an essential step after creating an executable. This step will ensure that the executable has been created correctly and is working as expected.
Here is a simple test to check whether the executable is working properly:
1. Create a simple Python script that displays a message when a button is clicked.
Here is an example script:
“`python
from tkinter import *
root = Tk()
label = Label(root, text=”Hello, world!”)
label.pack()
button = Button(root, text=”Click me!”, command=lambda: label.config(text=”Hello, again!”))
button.pack()
root.mainloop()
“`
Save the file as “hello.py” in a folder of your choice. 2.
Follow the steps outlined in the previous sections to create an executable from the Python script. 3.
Navigate to the “dist” folder where the executable is saved and double-click on the “.exe” file to run it. 4.
Verify that the executable is working as expected by clicking on the button. The text should change from “Hello, world!” to “Hello, again!” after clicking the button.
This simple test can give us an immediate indication of whether the executable is working properly. If we encounter any issues, we can review the script and the PyInstaller setup to determine where the problem lies.
Conclusion
After creating an executable using PyInstaller, we need to test it to ensure that it is working as expected. Simple tests such as clicking a button can give us an indication of whether the executable is working as intended.
Additionally, we need to keep in mind the details of executing the executable, including checking for error messages and installing any necessary dependencies such as the Visual C++ Redistributable. By following these steps, we can create and distribute our Python scripts efficiently and effectively.
