本文分享自华为云社区《从零开始学习python | 通过示例学习如何制作Python模式程序》，原文作者：Yuchuan 。
Python编程语言很容易学习。易于语法实现的各种库使其脱颖而出，这是它成为本世纪最流行的编程语言的众多原因之一。虽然学习很容易，但访问员通常会在建立模式程序逻辑时寻求您的方法。尽管听起来很棘手，但使用python却是小菜一碟。在本文中，我们将学习python中的各种模式程序。此博客涵盖以下主题：
- Star Pattern Programs
- Pyramid Pattern Program
- Half-Pyramid Pattern Program
- Diamond Shaped Pattern Program
- Start Pattern Program
- Hourglass Pattern Program
- Number Pattern Programs
- Simple Numbers In A Pyramid
- Pascal’s Triangle Pattern
- Diamond Pattern Program
- Characters Patter Programs
模式程序包含许多嵌套循环。因此，如果您不熟悉python中的循环，请确保查看有关python中的循环的详细教程。
星型程序
以下是python中的一些星型程序。
