问题 I have a form which contains some unique input fields and some others with duplicate names, like this: <form method="post"> Title: <input type="text" name="title" /><br /> Content: <input type="text" name="content" /><br /> Name: <input type="text" name="name" /><br /> Email: <input type="text" name="email" /><br /> Name: <input type="text" name="name" /><br /> Email: <input type="text" name="email" /><br /> Name: <input type="text" name="name" /><br /> Email: <input type="text" name="email"

问题 How can I store 08 and 09 into an int array? I understand that they cannot due to binary characteristics and have tried both... 0b08, 0b09 ... and ... 0B08, 0B09 with no luck. The following line of code is ideally what I'd like to have: final int[] monthValidDosInputs = {00, 01, 02, 03, 04, 05, 06, 07, 08, 09, 10, 11, 12}; Here is the error... ConvertDate.java:15: error: integer number too large: 08 ConvertDate.java:15: error: integer number too large: 09 Thanks! 回答1: When you start a literal

问题 I have this numpy array: a = np.array([[[1,2,3],[-1,-2,-3]],[[4,5,6],[-4,-5,-6]]]) b is a transpose of a . I want b be like this: b = np.array([[[1,-1],[2,-2],[3,-3]],[[4,-4],[5,-5],[6,-6]]]) Is it possible to do it in one line? EDIT: And if I have this instead: a = np.empty(3,dtype = object) a[0] = np.array([[1,2,3],[-1,-2,-3]]) a[1] = np.array([[4,5,6],[-4,-5,-6]]) How can I get b? 回答1: You can do it using np.transpose(a,(0,2,1)) : In [26]: a = np.array([[[1,2,3],[-1,-2,-3]],[[4,5,6],[-4,-5

问题 I'm getting an array from a C API, and I'd like to copy this to a std::array for further use in my C++ code. So what is the proper way of doing that ? I 2 uses for this, one is: struct Foo f; //struct from C api that has a uint8_t kasme[32] (and other things) c_api_function(&f); std::array<uint8_t, 32> a; memcpy((void*)a.data(), f.kasme, a.size()); And this class MyClass { std::array<uint8_t, 32> kasme; int type; public: MyClass(int type_, uint8_t *kasme_) : type(type_) { memcpy((void*)kasme

问题 I have two Arrays of unknown type...is there a way to check the elements are the same: public static boolean equals(Object a , Object b) { if (a instanceof int[]) return Arrays.equals((int[]) a, (int[])b); if (a instanceof double[]){ ////etc } I want to do this without all the instanceof checks.... 回答1: ArrayUtils.isEquals() from Apache Commons does exactly that. It also handles multi-dimensional arrays. 回答2: You should try Arrays.deepEquals(a, b) 回答3: Arrays utilities class could be of help

问题 I created a numpy array as follows: import numpy as np names = np.array(['NAME_1', 'NAME_2', 'NAME_3']) floats = np.array([ 0.1234 , 0.5678 , 0.9123 ]) ab = np.zeros(names.size, dtype=[('var1', 'U6'), ('var2', float)]) ab['var1'] = names ab['var2'] = floats The values in ab are shown below: array([(u'NAME_1', 0.1234), (u'NAME_2', 0.5678), (u'NAME_3', 0.9123)], dtype=[('var1', '<U6'), ('var2', '<f8')]) When I try to save ab as a .csv file using savetxt() command, np.savetxt('D:\test.csv',ab

问题 Does python have any equivalent to JavaScript's Array.prototype.some / every? Trivial JavaScript example: var arr = [ "a", "b", "c" ]; arr.some(function (element, index) { console.log("index: " + index + ", element: " + element) if(element === "b"){ return true; } }); Will output: index: 0, element: a index: 1, element: b The below python seems to be functionally equivalent, but I do not know if there is a more "pythonic" approach. arr = [ "a", "b", "c" ] for index, element in enumerate(arr):
