Finding the largest repeating substring

Here is a function I wrote that will take a very long text file. Such as a text file containing an entire textbook. It will find any repeating substrings and output the largest string. Right now it doesn't work however, it just outputs the string I put in For example, if there was a typo in which an entire sentence was repeated. It would output that sentence; given it is the largest in

找到最大的重复子字符串

这是我写的一个函数,它将需要一个非常长的文本文件。 如包含整个教科书的文本文件。 它会查找任何重复的子字符串并输出最大的字符串。 现在它不起作用,它只是输出我放入的字符串 例如,如果有整个句子重复的错字。 它会输出这个句子; 因为它是整个文件中最大的。 如果在输入整个段落两次时出现错字,则会输出该段落。 该算法采用第一个字符,查找任何匹配项,如果匹配并且长度最大,则存储子字符串。 然后它需要前2

way repeated measures anova using statsmodels?

I found this example, which explains how to perform a 2-way ANOVA. I was wondering how to do the same for a repeated-measures design. I did see this question, but I cannot assume independence of my repeated measurements. I'm using statsmodels version 0.5.0.dev-Unknown . Ideally, I'd like to use statsmodels, but if there's a viable solution using another library, I'd be inte

使用statsmodels重复测量anova吗?

我找到了这个例子,它解释了如何执行双向ANOVA。 我想知道如何为重复措施设计做同样的事情。 我确实看到了这个问题,但我不能假设我重复测量的独立性。 我正在使用statsmodels版本0.5.0.dev-Unknown 。 理想情况下,我想使用statsmodels,但如果有一个可行的解决方案使用另一个库,我也有兴趣听到它。 提前致谢! 没有什么内置的重复措施设计ANOVA,但我怀疑它不会很难支持。 如果您可以提供或指向我一个示例并提交

Python functions with multiple parameter brackets

I've been having trouble understanding what h(a)(b) means. I'd never seen one of those before yesterday, and I couldn't declare a function this way: def f (a)(b): return a(b) When I tried to do def f (a, b): , it didn't work either. What do these functions do? How can I declare them? And, finally, what's the difference between f(a, b) and f(a)(b) ? Functions with m

Python具有多个参数括号

我一直无法理解h(a)(b)含义。 我以前从未见过其中之一,我也无法这样声明函数: def f (a)(b): return a(b) 当我试图做def f (a, b):它也不起作用。 这些功能是做什么的? 我该如何申报? 最后, f(a, b)和f(a)(b)之间有什么区别 ? 正如您在尝试定义一个时所看到的那样,具有多个参数括号的函数不存在。 然而,有些函数返回(其他)函数: def func(a): def func2(b): return a + b return func2

How to properly handle Redis connections with Python / Python RQ?

What is the best pattern to handle Redis connections (both for interacting with Redis directly and indirectly through Python-RQ)? Generally, database connections need to be closed / returned to a pool when done, but I don't see how to do that with redis-py. That makes me wonder if I'm doing it the wrong way. Also, I have seen some performance dips when enqueuing jobs to RQ, which I&#

如何正确处理与Python / Python RQ的Redis连接?

处理Redis连接的最佳模式是什么(通过Python-RQ直接或间接与Redis进行交互)? 通常,数据库连接在完成时需要关闭/返回到池中,但是我不明白如何使用redis-py来完成此操作。 这让我怀疑我是否以错误的方式行事。 另外,在将工作排入RQ时,我看到一些性能下降,据我了解,这可能与连接使用/重用不良有关。 基本上,我有兴趣了解正确的模式,因此我可以验证或更正我们在应用程序中的内容。 非常感谢! 如果有更多有用的

memory Python object for nginx/uwsgi server

I doubt this is even possible, but here is the problem and proposed solution (the feasibility of the proposed solution is the object of this question): I have some "global data" that needs to be available for all requests. I'm persisting this data to Riak and using Redis as a caching layer for access speed (for now...). The data is split into about 30 logical chunks, each about

内存Python对象,用于nginx / uwsgi服务器

我怀疑这甚至是可能的,但这里是问题和提出的解决方案(提出的解决方案的可行性是这个问题的目标): 我有一些“全局数据”需要适用于所有请求。 我坚持将这些数据保存到Riak中,并使用Redis作为访问速度的缓存层(现在...)。 数据分成大约30个逻辑块,每个大约8 KB。 每个请求都需要读取这些8KB块中的4块,从Redis或Riak中读取32KB数据。 这对于任何需要读取的请求特定数据都是附加的(这是相当多的)。 假设每秒甚至有

Flattening a shallow list in Python

This question already has an answer here: Making a flat list out of list of lists in Python 31 answers If you're just looking to iterate over a flattened version of the data structure and don't need an indexable sequence, consider itertools.chain and company. >>> list_of_menuitems = [['image00', 'image01'], ['image10'], []] >>> import itertools >>> chain =

在Python中展开浅层列表

这个问题在这里已经有了答案: 在Python 31列表中列出一个扁平列表的答案 如果您只是在遍历数据结构的扁平版本并且不需要可索引序列,请考虑itertools.chain和company。 >>> list_of_menuitems = [['image00', 'image01'], ['image10'], []] >>> import itertools >>> chain = itertools.chain(*list_of_menuitems) >>> print(list(chain)) ['image00', 'image01', 'image10'] 它将处

Read specific sequence of lines in Python

I have a sample file that looks like this: @XXXXXXXXX VXVXVXVXVX + ZZZZZZZZZZZ @AAAAAA YBYBYBYBYBYBYB ZZZZZZZZZZZZ ... I wish to only read the lines that fall on the index 4i+2, where i starts at 0. So I should read the VXVXV (4*0+2 = 2)... line and the YBYB...(4*1 +2 = 6) line in the snippet above. I need to count the number of 'V's, 'X's,'Y

在Python中读取特定的行序列

我有一个如下所示的示例文件: @XXXXXXXXX VXVXVXVXVX + ZZZZZZZZZZZ @AAAAAA YBYBYBYBYBYBYB ZZZZZZZZZZZZ ... 所以我应该读VXVXV (4*0+2 = 2)...行和YBYB...(4*1 +2 = 6) VXVXV (4*0+2 = 2)...行。我希望只读取索引4i + 2上的行, YBYB...(4*1 +2 = 6)在上面的代码段中。 我需要计算'V's, 'X's,'Y's and 'B's并存储在一个预先存在的字典中。 fp = open(fi

scipy.quad trouble for decreasing functions over large ranges

I have a problem with scipy.quad . In short, I have a really long and complicated set of nested functions and integrals which include an integral of a decreasing function which must be integrated over the specific range 10^2 < x < 10^20. To demonstrate this problem simply, consider the integral of y=x^(-2) between these values using numpy.quad : import numpy as np from scipy.int

scipy.quad在大范围内减少功能的麻烦

我有一个scipy.quad的问题。 简而言之,我有一个非常长而复杂的嵌套函数和积分集合,其中包含积分递减函数,它必须在特定范围内集成10 ^ 2 <x <10 ^ 20。 为了简单地演示这个问题,使用numpy.quad这些值之间的y = x ^( - 2)的numpy.quad : import numpy as np from scipy.integrate import quad def func(x,z): "decreasing function to test" #print x,x**-2. return x**(-2

Python List comprehension with items() and enumerate()

I would like to implement this: asset_hist = [] for key_host, val_hist_list in am_output.asset_history.items(): for index, hist_item in enumerate(val_hist_list): row = collections.OrderedDict([("computer_name", key_host), ("id", index), ("hist_item", hist_item)]) asset_hist.append(row) Using list comprehension. This is as close as I can get: asset_hist = [collections.Orde

Python列表理解item()和枚举()

我想实现这一点: asset_hist = [] for key_host, val_hist_list in am_output.asset_history.items(): for index, hist_item in enumerate(val_hist_list): row = collections.OrderedDict([("computer_name", key_host), ("id", index), ("hist_item", hist_item)]) asset_hist.append(row) 使用列表理解。 这是尽可能接近,我可以得到: asset_hist = [collections.OrderedDict([("computer_name", k
