星球大战与Python之间的那些事
Python与星球大战背后的工业光魔
提起Python语言,很多人会想起系统运维、Web开发等工作。很少有人会知道Python也能够用于电影视觉特效的制作,其中就包括了《星球大战》某些电影特效的制作。
星战之父乔治·卢卡斯于1975年创建了工业光魔(全称:Industrial Light and Magic),从第一部《星球大战》起便参与了电影的特效制作。据Python官网介绍,工业光魔从1996年起开始使用Python语言,取代了此前的Unix shell脚本。工业光魔做出这个决定的原因,在于Python的学习难度低,开发速度快。当时,Python还只是1.4版本。
电影特效行业竞争十分激烈,制作公司会不断地寻找更加优秀的编程语言,提高工作效率。工业光魔也是一直在评估Python语言的使用,但是近20年以来,还没有找到一个更好的替代品。
工业光魔的资深技术总监Tommy Burnette曾经这样评价道:
- Python在我们的生产流程中扮演了至关重要的作用。如果没有它,像《星球大战》第二部这样的大项目就很难完成。从集体渲染到批量处理再到影片合成,Python将所有步骤都紧密的粘合在了一起。
由此可见Python的强大。
Star Wars API
你知道《星球大战》系列大战中出现了多少个种族,多少种飞船吗?这些答案都可以在Star Wars API中找到。
据开发者介绍,Star Wars API是全球首个量化的、可供编程使用的星战数据集。开发者经过漫长的搜集和整理,汇总了星战系列电影中的人物、种族、星球、飞船等详细数据。目前,这个API中已经收录了《原力觉醒》中的新数据。API的作者还用Python开发了一个helper库。
我们来看看可以用这个库做些什么。
将所有星球按大小排列:
import swapi for planet in swapi.get_all("planets").order_by("diameter"): print(planet.name)
查看哪些人开过1艘以上的飞船:
import swapi for people in swapi.get_all("people").iter(): if len(people.starships) > 1: print(people.name)
检索Jar Jar Binks是否在电影中出现:
import swapi pm = swapi.get_film(4) jj = swapi.get_person(36) for c in pm.get_characters().iter(): if c.name == jj.name: print("Why George, why.")
Python编写的Star Wars小游戏
最后,再与大家分享一个国外开发者用Python开发的星战相关游戏,希望大家喜欢。
这个游戏类似现在的跑酷,通过上下左右方向键控制。
是不是很酷!很赞!很期待!

PHP and Python have their own advantages and disadvantages, and the choice depends on project needs and personal preferences. 1.PHP is suitable for rapid development and maintenance of large-scale web applications. 2. Python dominates the field of data science and machine learning.

Python and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.

In VS Code, you can run the program in the terminal through the following steps: Prepare the code and open the integrated terminal to ensure that the code directory is consistent with the terminal working directory. Select the run command according to the programming language (such as Python's python your_file_name.py) to check whether it runs successfully and resolve errors. Use the debugger to improve debugging efficiency.

VS Code can be used to write Python and provides many features that make it an ideal tool for developing Python applications. It allows users to: install Python extensions to get functions such as code completion, syntax highlighting, and debugging. Use the debugger to track code step by step, find and fix errors. Integrate Git for version control. Use code formatting tools to maintain code consistency. Use the Linting tool to spot potential problems ahead of time.

Docker uses Linux kernel features to provide an efficient and isolated application running environment. Its working principle is as follows: 1. The mirror is used as a read-only template, which contains everything you need to run the application; 2. The Union File System (UnionFS) stacks multiple file systems, only storing the differences, saving space and speeding up; 3. The daemon manages the mirrors and containers, and the client uses them for interaction; 4. Namespaces and cgroups implement container isolation and resource limitations; 5. Multiple network modes support container interconnection. Only by understanding these core concepts can you better utilize Docker.

VS Code extensions pose malicious risks, such as hiding malicious code, exploiting vulnerabilities, and masturbating as legitimate extensions. Methods to identify malicious extensions include: checking publishers, reading comments, checking code, and installing with caution. Security measures also include: security awareness, good habits, regular updates and antivirus software.

VS Code can run on Windows 8, but the experience may not be great. First make sure the system has been updated to the latest patch, then download the VS Code installation package that matches the system architecture and install it as prompted. After installation, be aware that some extensions may be incompatible with Windows 8 and need to look for alternative extensions or use newer Windows systems in a virtual machine. Install the necessary extensions to check whether they work properly. Although VS Code is feasible on Windows 8, it is recommended to upgrade to a newer Windows system for a better development experience and security.

Python excels in automation, scripting, and task management. 1) Automation: File backup is realized through standard libraries such as os and shutil. 2) Script writing: Use the psutil library to monitor system resources. 3) Task management: Use the schedule library to schedule tasks. Python's ease of use and rich library support makes it the preferred tool in these areas.
