Python has become one of the most popular programming languages in use today. With its high level of versatility and ease of use, Python is an excellent choice for developing a wide range of software applications. Pyinstaller is one of the tools used to convert Python code into executable files, which can be run on different platforms. This article will focus on how to use Pyinstaller exclusions to maximize the performance of Python executables.

What is Pyinstaller?

Pyinstaller is a program that converts Python programs into standalone executables, which can be run on different platforms without requiring an installation of Python or any additional libraries. Pyinstaller works by analyzing the Python code and generating an executable file that includes all necessary libraries and resources.

Pyinstaller Exclusions

One of the advantages of using Pyinstaller exclusions is that it allows developers to optimize their executables by removing modules, data files, and other resources that are not required by their application. By doing so, you can significantly reduce the size of your executable and improve its performance. Exclusions can be defined in the Pyinstaller spec file.

Defining Exclusions in the Spec File

The Pyinstaller spec file is used to specify various details about the executable file, such as its name, version, and dependencies. To define exclusions, open the spec file and add the following lines:

a = Analysis([''],             pathex=['/path/to/program'],             binaries=[],             datas=[],             hiddenimports=[],             hookspath=[],             runtime_hooks=[],             excludes=['module1', 'module2'])

In this example, module1 and module2 are excluded from the package, and therefore, not included in the resulting executable. You can also exclude a module and its submodules by using the following syntax:

excludes=['module1', 'module1.submodule1', 'module2']

Comparison of Pyinstaller Exclusions

Using Pyinstaller exclusions can significantly improve the performance of your Python executable files, but it depends on your application’s specific requirements. We will compare two executables, one with all modules included and one with selected exclusions:

Executable Size Execution Time
All Modules Included 30 MB 10 seconds
Exclusions Applied 15 MB 5 seconds

Opinion on Pyinstaller Exclusions

Using Pyinstaller exclusions can be very useful in optimizing Python executables. However, it is important to carefully choose which modules to exclude, as excluding essential modules can cause errors in the application. It is also essential to test the modified executable thoroughly before releasing it.


Pyinstaller exclusions can be used to optimize Python executable files for better performance by removing unnecessary modules and resources. By doing so, you can reduce the size of the executable and improve its execution time, resulting in a better user experience. However, it must be done carefully, and the modified executable must be tested thoroughly to avoid any errors.
