python circular import python循环导入问题

遇到的问题是因为模块之间存在循环导入(circular import),导致了ImportError。循环导入是指两个或多个模块相互导入对方,如模块A导入了模块B的方法,模块B又导入了模块A的方法,从而导致其中一个模块在完全初始化之前就被另一个模块尝试导入,进而引发错误。 解决循环导入问题的方法 重构代码结构: 尽量避免模块之间的直接相互导入。可以考虑将公共的部分抽象出来,放到单独的模块中。

boost库---circular_buffer用法

Boost.Circular_buffer维护了一块连续内存块作为缓存区,当缓存区内的数据存满时,继续存入数据就覆盖掉旧的数据。 它是一个与STL兼容的容器,类似于 std::list或std::deque,并且支持随机存取。circular_buffer 被特别设计为提供固定容量的存储大小。当其容量被用完时,新插入的元素会覆盖缓冲区头部或尾部(取决于使用何种插入操作)的元素。 circular

Python报错most likely due to a circular import

import numpy as npa=np.zeros(1)print(a)    因为在学习numpy这个库,所以顺手把文件名字命名成了numpy,但是在运行中发现报错。 将文件名字改成其他的再次运行即可,注意: 1.如果文件名与库名相同,改文件名会同时把文件里的import 库改掉,所以文件里面的内容也要检查一下。 2.今后命名时避开常用库,以及编程中尽量使用英文与数字的结合
