What is the best way to sanitize user input for a Python-based web application? Is there a single function to remove HTML characters and any other necessary characters combinations to prevent an XSS or SQL injection attack? Here is a snippet that will remove all tags not on the white list, and all tag attributes not on the attribues whitelist (so you can't use onclick ). It is a modified
清理基于Python的Web应用程序的用户输入的最佳方式是什么？ 是否有单个函数来删除HTML字符和任何其他必要的字符组合以防止XSS或SQL注入攻击？ 这里是一个代码片段，它将删除所有不在白名单上的标签，以及所有不属于白名单的标签属性（所以你不能使用onclick ）。 它是http://www.djangosnippets.org/snippets/205/的一个修改版本，使用属性值的正则表达式来防止人们使用href="javascript:..." ，以及http： //ha.
I am trying to complete a form on a website automatically for academic purposes using Python's mechanize. When a human completes the form and submits it, there is no recaptcha. But when I fill in the controls for the form via mechanize in Python, there is a hidden control that is a recaptcha apparently. <HiddenControl(recaptcha_response_field=manual_challenge)> Since this recaptch
我正在尝试使用Python的机械化自动完成学术目的的网站表单。 当一个人完成表格并提交时，没有任何回复。 但是当我通过Python中的机械化来填充表单的控件时，显然有一个隐藏的控件是一个recaptcha。 <HiddenControl(recaptcha_response_field=manual_challenge)> 由于这种回忆从来没有向人类展示，我不知道它在寻找什么，或者说这是一个手工挑战。 因此，我的问题是，我怎样才能通过这个挑战，让我可以继续自动化/
I'm trying to print a PDF with Python, without opening the PDF viewer application (Adobe, Foxit etc.). I need also to know when printing has finished (to delete the file). Here I found this implementation : import win32ui, dde, os.path, time from win32api import FindExecutable from os import spawnl, P_NOWAIT ... pd = "C:\temp\test.pdf" pdbits = os.path.split(pd) readerexe = FindExecutable
我试图用Python打印PDF，而不用打开PDF查看器应用程序（Adobe，Foxit等）。 我还需要知道何时完成打印（删除文件）。 在这里我找到了这个实现 ： import win32ui, dde, os.path, time from win32api import FindExecutable from os import spawnl, P_NOWAIT ... pd = "C:\temp\test.pdf" pdbits = os.path.split(pd) readerexe = FindExecutable(pdbits[1],pdbits[0]) spawnl(P_NOWAIT,readerexe[1],"DUMMY") #I added "DUMM
Basically, I want to disable a certain Combobox, based on the value of another combobox. I couldn't find a answer to this question, maybe because it's very uncommon to do this to a Combobox. I have a code more or less as follow... self.cBox1Var=tki.StringVar() self.cBox1=ttk.Combobox(self.mframe, width=16, textvariable=self.cBox1Var, state='readonly',values=['Text entry','Comb
基本上，我想根据另一个组合框的值禁用某个组合框。 我无法找到这个问题的答案，也许是因为这对Combobox来说是非常罕见的。 我有一个或多或少的代码如下... self.cBox1Var=tki.StringVar() self.cBox1=ttk.Combobox(self.mframe, width=16, textvariable=self.cBox1Var, state='readonly',values=['Text entry','Combo box','Check button']) self.cBox1.grid(row=0,column=1,sticky=tki.W) self.cBox1Var.se
I have a floating point number, say 135.12345678910 . I want to concatenate that value to a string, but only want 135.123456789 . With print, I can easily do this by doing something like: print "%.9f" % numvar with numvar being my original number. Is there an easy way to do this? With python < 3 (eg 2.6 [see comments] or 2.7), there are two ways to do so. # Option one older_method_str
我有一个浮点数，比如135.12345678910 。 我想将该值连接到一个字符串，但只想要135.123456789 。 通过打印，我可以通过执行以下操作轻松完成此操作： print "%.9f" % numvar numvar是我的原始数字。 是否有捷径可寻？ 使用python <3（例如2.6 [见注释]或2.7），有两种方法可以这样做。 # Option one older_method_string = "%.9f" % numvar # Option two newer_method_string = "{:.9f}".format(numvar) 但是请
EDIT: I've found an interesting issue here. This link shows that gensim uses randomness in both training and inference steps. So what it suggested here is to set a fixed seed in order to get same results every time. Why however am I getting for every topic the same probability? What I want to do is to find for every twitter user her topics and calculate the similarity between twitter use
编辑：我发现这里有一个有趣的问题。 该链接显示gensim在训练和推理步骤中都使用随机性。 所以它在这里建议的是设置一个固定的种子，以便每次获得相同的结果。 为什么我要为每个主题获取相同的概率？ 我想要做的是为每个推特用户找到她的主题，并根据主题的相似性计算推特用户之间的相似度。 是否有可能为gensim中的每个用户计算相同的主题，或者是否必须计算主题词典并聚集每个用户主题？ 总的来说，在gensim中基于主题

I have this order form which allows my users to create an order. An order consists of multiple tuples of (producetype, quantity) . Producetype should be rendered in a <select> form while quantity can just be an input. The choices of producetype should be dynamically added because that could change. Currently, I've written this in bare html I would like to use WTForm for this becau
我有这个订单，允许我的用户创建订单。 一个订单由(producetype, quantity)的多个元组组成。 Producetype应该以<select>形式呈现，而数量只能是输入。 农产品类型的选择应该动态添加，因为这可能会改变。 目前，我已经写在这个纯粹的HTML 我想为此使用WTForm，因为WTForm确实简化了我的代码。 但是，我无法这样做： 码： class OrderEntryForm(Form): quantity = IntegerField('Quantity',
I am writing a series of tests for a palindrome solver. I came across the interesting palindrome in Hebrew: טעם לפת תפל מעט Which is a palindrome, but the letter Mem has both a regular form (מ) and a "final form" (ם), how it appears as the last letter in a word. But short of hardcoding that "0x5de => 0x5dd" in my program, I was not able to figure out a way to programm
我正在为回文求解器编写一系列测试。 我遇到了希伯来语有趣的回文： טעםלפתתפלמעט 这是一个回文，但Mem这个字母既有常规形式也有“最终形式”（ם），它看起来像是一个单词中的最后一个字母。 但是在我的程序中缺少硬编码，即“0x5de => 0x5dd”，我无法找到一种通过编程方式依靠Unicode，Python或将这两者视为相同的库的方法。 我做过的事情： s = 'טעם לפת תפל מעט' s.casefold() # Python 3.4 s.lower() s.upper() impor
