简介:当你在Python中遇到“RecursionError: maximum recursion depth exceeded while calling a Python object”这个错误时,通常意味着你的递归函数调用次数过多,超过了Python的默认递归深度限制。本文将解释这个错误的原因,并提供几种解决方案。 千帆应用开发平台“智能体Pro”全新上线 限时免费体验 面向慢思考场景,支持低...
Assignment statements in Python do not copy objects, they create bindings between a target and an object. For collections that are mutable or contain mutable items, a copy is sometimes needed so one can change one copy without changing the other. This module provides generic shallow and deep co...

append(20) >>> a [10, 20] >>> b [10] 默认参数为可变对象 默认参数是函数的一部分,不会在调用的过程中产生。 如果函数的默认参数是可变对象,会有很大的风险,如下所示。 # 定义的函数,使其参数s的默认值为空list,这是一个可变对象,mutable object >>> def f(s=[]): ... s.append(5) ......
