在处理更复杂的SQL语句时,一些专门的构建器库如sqlbuilder会更加方便。 首先安装sqlbuilder: pip install sqlbuilder 1. 然后使用它来构建复杂的SQL语句: from sqlbuilder.smartsql import Q, T, Field from sqlbuilder.smartsql.dialects.mysql import compile as mysql_compile # 构建复杂查询 def create_complex_s...

建造者模式(Builder Pattern):将一个复杂对象的构建与它的表示分离,使得同样的构建过程可以创建不同的表示。 原型模式(Prototype Pattern):通过复制现有的实例来创建新的对象,而不是使用构造函数。 适配器模式(Adapter Pattern):将一个类的接口转换成客户希望的另一个接口。适配器模式可以让原本由于接口不兼容而不能...
PyPika is a Python API for building SQL queries. The motivation behind PyPika is to provide a simple interface for building SQL queries without limiting the flexibility of handwritten SQL. Designed with data analysis in mind, PyPika leverages the builder design pattern to construct queries to avoid...
为了大家能够对人工智能常用的 Python 库有一个初步的了解,以选择能够满足自己需求的库进行学习,对目前较为常见的人工智能库进行简要全面的介绍。 1、Numpy NumPy(Numerical Python)是Python的一个扩展程序库,支持大量的维度数组与矩阵运算,此外也针对数组运算提供大...
