揭秘 Python 的打包之谜:PyInstaller 终极指南

python Package PyInstaller executable file for distribution

Introduction

PyInstaller is an open source tool used to package Python scripts into executable files so that they can run independently of the Python interpreter. It is useful for distributing and deploying Python applications as it eliminates dependency on the Python environment and simplifies the application installation and distribution process.

Install PyInstaller

To install PyInstaller, use the following command:

# hello_world.py

print("Hello World!")

To package this application, run the following command:

pyinstaller hello_world.py

This will generate the following files in the dist directory:

  • hello_world.exe:executable file
  • hello_world.spec:Packaging specification file

Custom packaging options

PyInstaller provides many options to customize the packaging process. For example, you can include or exclude certain files, set the icon for an executable file, or specify a virtual environment. See the PyInstaller documentation for a complete list of options.

Precautions

When packaging Python applications, you need to pay attention to some things:

  • Make sure all dependencies in your application are installed correctly.
  • PyInstaller cannot package C extensions.
  • The packaged application may be larger in size than the original script.

in conclusion

PyInstaller is a powerful tool for packaging Python applications into standalone executables. By following the guidance in this article, you can easily get the hang of PyInstaller and start distributing your code for others to use.

How to Use Python to Find the Zipf Distribution of a Text FileHow to Use Python to Find the Zipf Distribution of a Text FileMar 05, 2025 am 09:58 AM

This tutorial demonstrates how to use Python to process the statistical concept of Zipf's law and demonstrates the efficiency of Python's reading and sorting large text files when processing the law. You may be wondering what the term Zipf distribution means. To understand this term, we first need to define Zipf's law. Don't worry, I'll try to simplify the instructions. Zipf's Law Zipf's law simply means: in a large natural language corpus, the most frequently occurring words appear about twice as frequently as the second frequent words, three times as the third frequent words, four times as the fourth frequent words, and so on. Let's look at an example. If you look at the Brown corpus in American English, you will notice that the most frequent word is "th

Mathematical Modules in Python: StatisticsMathematical Modules in Python: StatisticsMar 09, 2025 am 11:40 AM

Python's statistics module provides powerful data statistical analysis capabilities to help us quickly understand the overall characteristics of data, such as biostatistics and business analysis. Instead of looking at data points one by one, just look at statistics such as mean or variance to discover trends and features in the original data that may be ignored, and compare large datasets more easily and effectively. This tutorial will explain how to calculate the mean and measure the degree of dispersion of the dataset. Unless otherwise stated, all functions in this module support the calculation of the mean() function instead of simply summing the average. Floating point numbers can also be used. import random import statistics from fracti

Serialization and Deserialization of Python Objects: Part 1Serialization and Deserialization of Python Objects: Part 1Mar 08, 2025 am 09:39 AM

Serialization and deserialization of Python objects are key aspects of any non-trivial program. If you save something to a Python file, you do object serialization and deserialization if you read the configuration file, or if you respond to an HTTP request. In a sense, serialization and deserialization are the most boring things in the world. Who cares about all these formats and protocols? You want to persist or stream some Python objects and retrieve them in full at a later time. This is a great way to see the world on a conceptual level. However, on a practical level, the serialization scheme, format or protocol you choose may determine the speed, security, freedom of maintenance status, and other aspects of the program
