Excel: Sequential numbers + specified start and end values + shift column data down

由 房东的猫 提交于 2019-12-24 12:35:06
问题 I have a start value in column "A" (02) And an end value in column "B" (06) In column "C" I'd like to list the range of number sequentially using the start and end values in columns "A" and "B". However I'd also like to shift the cell data down to stop any data overlapping. To go one step further, I don't know if this is possible, but it would help if the data from the original row could be duplicated in each of the new rows that have been created with the sequential values. Edit: This code

bash mass rename files in folders and subfolders with sequential number

由 孤街浪徒 提交于 2019-12-24 00:37:45
问题 I need a bash script which does the following: for every file of a certain type present in a folder and in its sub folders it prepends a sequential number (4 digits) followed by a separator (-) So for example I have: /Queen/(1986) A Kind of Magic/01.One vision.mp3 /Queen/(1986) A Kind of Magic/02.A kind of magic.mp3 /Queen/(1986) A Kind of Magic/cover.jpg /Queen/(1991) Innuendo/01.Innuendo.mp3 /Queen/(1991) Innuendo/02.Headlong.mp3 /Queen/(1991) Innuendo/cover.jpg /Queen/(1991) Innuendo

What is the fastest way to retrieve sequential data from database?

由 ε祈祈猫儿з 提交于 2019-12-23 05:43:31
问题 I have a lot of rows in a database and it must be processed, but I can't retrieve all the data to the memory due to memory limitations. At the moment, I using LIMIT and OFFSET to retrieve the data to get the data in some especified interval. I want to know if the is the faster way or have another method to getting all the data from a table in database. None filter will be aplied, all the rows will be processed. 回答1: SELECT * FROM table ORDER BY column There's no reason to be sucking the

李宏毅 Keras2.0演示

李宏毅 Keras2.0演示 不得不说李宏毅老师讲课的风格我真的十分喜欢的。 在keras2.0中，李宏毅老师演示的是手写数字识别（这个深度学习框架中的hello world） 创建网络 首先我们需要建立一个Network scratch，input是28*25的dimension，其实就是说这是一张image，image的解析度是 2 8 ∗ 2 8，我们把它拉成长度是 2 8 ∗ 2 8维的向量。 output呢？ 现在做的是手写数字辨识，所以要决定它是0-9的哪个数字，output就是每一维对应的数字，所以output就是10维。 中间假设你要两个layer，每个layer有500个hidden neuro，那么你会怎么做呢。 如果用Keras的话，首先需要声明一个network model=Sequential() 然后你需要吧第一个hidden layer加进去，需要怎么做呢？很简单，只需要add即可。 model.add(Dense(input_dim=28*28,units=500,activation='relu')) Dense意思就是说你加一个全连接网络，可以加其他的，比如加Con2d，就是加一个convolution layer，这些都很简单。input_dim是说输入的维度是多少，units表示hidden layer的neuro 数，

replace pattern with a sequential number string in python

由 余生长醉 提交于 2019-12-19 03:14:14
问题 I'm trying to achieve the following replacement in python. Replace all html tags with {n} & create a hash of [tag, {n}] Original string -> " <h> This is a string. </H><P> This is another part. </P> " Replaced text -> "{0} This is a string. {1}{2} This is another part. {3}" Here's my code. I've started with replacement but I'm stuck at the replacement logic as I cannot figure out the best way to replace each occurrence in a consecutive manner i.e with {0}, {1} and so on: import re text = "<h>

Sequentially number rows by keyed group in SQL?

由 折月煮酒 提交于 2019-12-17 23:23:51
问题 Is there a way in SQL to sequentially add a row number by key group ? Assume a table with arbitrary (CODE,NAME) tuples. Example table: CODE NAME ---- ---- A Apple A Angel A Arizona B Bravo C Charlie C Cat D Dog D Doppler D Data D Down Desired projection using CODE as the grouping attribute: CODE C_NO NAME ---- ---- ---- A 0 Apple A 1 Angel A 2 Arizona B 0 Bravo C 1 Charlie C 0 Cat D 0 Dog D 1 Data D 2 Down D 3 Doppler Thanks, 回答1: SQL Server Oracle Postgres Sybase MySQL doesn't AFAIK.

SQL: create sequential list of numbers from various starting points

由 余生长醉 提交于 2019-12-12 16:39:19
问题 I'm stuck on this SQL problem. I have a column that is a list of starting points ( prevdoc ), and anther column that lists how many sequential numbers I need after the starting point ( exdiff ). For example, here are the first several rows: prevdoc | exdiff ---------------- 1 | 3 21 | 2 126 | 2 So I need an output to look something like: 2 3 4 22 23 127 128 I'm lost as to where even to start. Can anyone advise me on the SQL code for this solution? Thanks! 回答1: ;with a as ( select prevdoc + 1

Incrementing a counter variable in verilog: combinational or sequential

问题 I am implementing an FSM controller for a datapath circuit. The controller increments a counter internally. When I simulated the program below, the counter was never updated. reg[3:0] counter; //incrementing counter in combinational block counter = counter + 4'b1; However, on creating an extra variable, counter_next, as described in Verilog Best Practice - Incrementing a variable and incrementing the counter only in the sequential block, the counter gets incremented. reg[3:0] counter, counter
