Detecting whether a Flask app handles a URL

I have a case for having a preliminary frontend Flask app before continuing to my main app. I've implemented it using a "middleware" pattern: class MyMiddleware(object): def __init__(self, main_app, pre_app): self.main_app = main_app self.pre_app = pre_app def __call__(self, environ, start_response): # check whether pre_app has a rule for this URL

检测Flask应用程序是否处理URL

在继续使用我的主应用程序之前,我有一个初步的前端Flask应用程序的案例。 我已经使用“中间件”模式实现了它: class MyMiddleware(object): def __init__(self, main_app, pre_app): self.main_app = main_app self.pre_app = pre_app def __call__(self, environ, start_response): # check whether pre_app has a rule for this URL with self.pre_app.request_context(environ) a

np.isnan on arrays of dtype "object"

I'm working with numpy arrays of different data types. I would like to know, of any particular array, which elements are NaN. Normally, this is what np.isnan is for. However, np.isnan isn't friendly to arrays of data type object (or any string data type): >>> str_arr = np.array(["A", "B", "C"]) >>> np.isnan(str_arr) Traceback (most recent call last): File "<std

在dtype“object”数组上的np.isnan

我正在处理不同数据类型的numpy数组。 我想知道,在任何特定的数组中,哪些元素是NaN。 通常,这是np.isnan的用途。 但是, np.isnan对数组类型object (或任何字符串数据类型)不友好: >>> str_arr = np.array(["A", "B", "C"]) >>> np.isnan(str_arr) Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: Not implemented for this type >>>

Return multiple lists from comprehension in python

Is there any way in Python to return multiple lists from a comprehension? I want to do something to the effect of: x,y = [i,(-1*j) for (i,j) in enumerate(range(10))] # x = [0 .. 9] # y = [0 .. -9] that's a dumb example, but I'm just wondering if it's possible. x,y =zip(* [(i,(-1*j)) for (i,j) in enumerate(range(10))] ) 你只需解压缩列表xy = [(1,2),(3,4),(5,6)] x,y = zip(*xy) # x =

如何使用Python在相同的TCL shell上运行命令

我有用TCL编写的所有库。 我想在Python中创建一个图形用户界面,它将有几个按钮和其他选项。 在开始的时候TCL shell会打开。 当我点击按钮时,相应的命令将在TCL外壳上执行。 是否可以在不关闭TCL外壳的情况下在TCL的同一个外壳上触发命令? 我搜索谷歌并在Python中找到Tkniter模块,但每次我需要执行命令时都会打开TCL shell。 您当然可以使用Tkinter在同一个Tcl解释器中运行一系列命令: Python 2.7.9 (default, Feb
