When are Python circular imports fatal?

In your Python package, you have:

an __init__.py that designates this as a Python package
a module_a.py, containing a function action_a() that references an attribute (like a function or variable) in module_b.py, and
a module_b.py, containing a function action_b() that references an attribute (like a function or variable) in module_a.py.

This situation can introduce a circular import error: module_a attempts to import module_b, but can't, because module_b needs to import module_a, which is in the process of being interpreted.

But, sometimes Python is magic, and code that looks like it should cause this circular import error works just fine!

	function unorderArr(arr){
	let carr = arr.concat();
	carr.sort(function(x,y){
	return 0.5-Math.random()
	})
	return carr
	}

	//base64转 bob文件
	function dataURItoBlob(dataURI) {
	// convert base64/URLEncoded data component to raw binary data held in a string
	var byteString;
	if (dataURI.split(',')[0].indexOf('base64') >= 0)
	byteString = atob(dataURI.split(',')[1]);
	else
	byteString = unescape(dataURI.split(',')[1]);

	// separate out the mime component

	添加的自定义函数
	filename：编译后的目标文件，相对路径是 dist
	template：明确的模板，相对路径是项目根目录
	然后，来源，是 entry一一对应的入口（这是隐藏的）
	大原则，就是，和 webpack.base.config.js的Entry一一对应
