将数组转换为对象

蓝咒 提交于 2019-12-06 14:00:48
有时候,出于某种目的,需要将数组转化成对象,一个简单快速的方法是就使用展开运算符号(...): var fruits = [“banana”, “apple”, “orange”, “watermelon”]; var fruitsObj = { …fruits }; console.log(fruitsObj); // returns {0: “banana”, 1: “apple”, 2: “orange”, 3: “watermelon”, 4: “apple”, 5: “orange”, 6: “grape”, 7: “apple”} 来源: https://www.cnblogs.com/ll15888/p/11988415.html

''' 列表 ''' lst = [1, "apple", "bb"] ''' 列表相对于字符串,不仅可以存放不同的数据类型,而且可以存放大量的数据。32位Python可以存放:536870912个元素,64位可以存放: 115291504606846975个元素。而且列表是有序的(按照你保存的顺序),有索引,可以切片方便取值。 ''' ''' 1、列表的索引 ''' lst = ["apple", "banana", "orange", "strawberry"] print(lst[0]) # apple print(lst[1]) # banana print(lst[-1]) # strawberry lst[2] = "桔子" # 注意,列表是可以发送改变的,这里和字符串不一样 print(lst) # ['apple', 'banana', '桔子', 'strawberry'] s1 = "apple" # s1[0] = "A" # TypeError: 'str' object does not support item assignment print(s1) ''' 2、列表的切片 ''' lst = ["apple", "banana", "orange", "strawberry"] print(lst[0:3]) # ['apple', 'banana'

How do I create a new data table in Orange?

生来就可爱ヽ(ⅴ<●) 提交于 2019-12-03 15:51:39
I am using Orange (in Python) for some data mining tasks. More specifically, for clustering. Although I have gone through the tutorial and read most of the documentation, I still have a problem. All the examples in docs and tutorials assume that I have a tab delimited table with data in it. However, there is nothing saying how one can go about creating a new table from scratch. For example, I want to create a table for word frequencies across different documents. Maybe I am missing something so if anyone has any insight it'd be appreciated. Thanks George EDIT: This is how I create my table

IOC的单例和多例

  Spring容器在默认情况下管理的bean是单例(singleton)的,即该bean只会创造一个对象,无论之后调用多少次该bean,都只会返回同一个对象。   多例(prototype)模式,每次调用同一个bean,都会创造不同的对象。 实验:   两个实验类: package com.tsvv.pojo; public class Apple { } --------------------------------------- package com.tsvv.pojo; public class Orange { }   application.xml: <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd"> <!-- scope属性控制当前bean的创建模式:

I'm tryng to do something similar but with "[@]" to iterate over the array. Thanks in advance, 回答1: ${!ARRAYNAME[@]} means "the indices of ARRAYNAME ". As stated in the bash man page since ARRAYNAME is set, but as a string, not an array, it returns 0 . Here's a solution using eval . #!/usr/bin/env bash ARRAYNAME='FRUITS' FRUITS=( APPLE BANANA ORANGE )

Here is it . gcolor2 utility shows HSV at the center of the lid to be (22, 59, 100). The question is how to choose the limits of the color then? I tried min = (18, 40, 90) and max = (27, 255, 255), but have got unexpected Here is the Python code: import cv in_image = 'kaffee.png' out_image = 'kaffee_out.png' out_image_thr = 'kaffee_thr.png' ORANGE_MIN = cv.Scalar(18, 40, 90) ORANGE_MAX = cv.Scalar(27, 255, 255) COLOR_MIN = ORANGE_MIN COLOR_MAX = ORANGE_MAX
