1. 解释错误含义 TypeError: iteration over non-sequence 错误表明你尝试对一个非序列类型(non-sequence type)的对象进行迭代操作。在 Python 中,序列类型包括列表(list)、元组(tuple)、字符串(string)等,它们都是可迭代对象。如果尝试对如整数(int)、浮点数(float)、NoneType 或自

当函数或操作应用于不适当类型的对象时,Python 中会引发 TypeError。 例如,添加整数和字符串对象会返回 TypeError。 当您尝试迭代不可迭代的对象时,会出现错误TypeError: iteration over non-sequence。 本篇文章将介绍修复TypeError: iteration over non-sequence。 重现Python 中 TypeError: iteration over non-sequence...
The errorTypeError: iteration over non-sequenceoccurs when you try to iterate over an object which is not iterable. This tutorial will teach you to fixTypeError: iteration over non-sequencein Python. Now you have understood the cause ofTypeError, let’s recreate theiteration over non-sequenceerro...
This makes multiple // iterations over the iterable safe for non-trivial cases, // such as use of break or nested looping over the same iterable. let index = 0; return { next: () => { if (index < this.data.length) { return {value: this.data[index++], done: false} } else {...
In such scenario, certain workloads may perform the worst on VMs, but, would execute faster over the containers, virtualized containers or bare-metal (non-virtualized) platforms [133]. Lower execution times may mean higher energy efficiency, lesser users costs and vice versa; however, energy ...
The objective is separable over different variables. Distributed algorithm is designed by iteratively solving the following convex smaller programming: minxf(x,y)s.t.x∈C1 and minyf(x,y)s.t.y∈C2 until convergence. In Xu and Li (2013), the problem is formulated as a general workload ...
For example, the methodNonRepeatablein the example below yields a non-repeatable sequence of three integers. The second loop overnrdoes nothing, because the non-repeatable sequence has already been consumed. Although this example is somewhat contrived, non-repeatable sequences are unfortunately not al...

The figure shows the variable bound ranges for the real and imaginary components of the voltages averaged over all buses of the same shortest path in terms of the number of transmission lines from the reference bus. The iteration count for OBBT is shown on the x-axis. The figure shows the...
