How do I use the new SVN merge-tracking?

问题 In my existing (Pre-SVN 1.5) merge strategy, we create a copy of the Trunk (called BasePoint) at the moment of branch-creation for referencing later during the merge. When we need to merge a branch back into the trunk, we perform 2 operations. Merge from BasePoint to LatestTrunk (Trunk has likely moved on since the original branch) into Working copy of Branch and then commit. At this point we typically check that the merge into the branch has not damaged anything Merge from LatestTrunk to

Merge two columns into one within the same data frame in pandas/python

问题 I have a question to merge two columns into one in the same dataframe(start_end), also remove null value. I intend to merge 'Start station' and 'End station' into 'station', and keep 'duration' according to the new column 'station'. I have tried pd.merge, pd.concat, pd.append, but I cannot work it out. dataFrame of Start_end: Duration End station Start station 14 1407 NaN 14th & V St NW 19 509 NaN 21st & I St NW 20 638 15th & P St NW.

<范浩强treap>-函数式平衡树 范好强treap是一种毒瘤treap,它并不用通过旋转来达到平衡,它主要有两种操作: merge(x,y): 将x的子树和y的子树合并起来;{ 注意:merge操作中,x子树中的最大值永远会小于等于y子树中的最小值 所以在merge的过程中只需要考虑随机值,而不需考虑key值 }所以merge时要不就x连接在y的左儿子, 要不就y连接在x的右儿子,这时就需通过随机值来确定哪个为儿子。 1 int merge(int x,int y){ 2 //printf("merge:%d %d\n",x,y); 3 if(!x||!y) return x+y; 4 else{ 5 if(t[x].fix<t[y].fix){ 6 int r=copynode(x); 7 t[r].son[1]=merge(t[r].son[1],y); 8 update(r); 9 return r; 10 } 11 else{ 12 int r=copynode(y); 13 t[r].son[0]=merge(x,t[r].son[0]); 14 update(r); 15 return r; 16 } 17 } 18 } merge split(k,x,y): 将小于等于k值的数分离到以x为根的子树中,另外一部分分离到y;只需判断当前节点与k的关系, 若小于等于K

问题 I have an extensive DATE-TIME conversion class, but i came across a scenario that i cannot resolve: I have a java.util.date: Tue May 10 00:00:00 BST 2011 I have a java.sql.time: 03:58:44 I need to create a java.util.date: Tue May 10 03:58:44 BST 2011 The only approach i came up with is: public static Date getDate(Date date, Time time) { Calendar calendar=Calendar.getInstance(); calendar.set(date.getYear(), date.getMonth(), date.getDay(), time.getHours(), time.getMinutes(), time.getSeconds());

(e.g. df1 and df2 has an identical row as "aaa, bbb,

How to detect merged cells in excel with openpyxl

我是研究僧i 提交于 2020-01-29 03:49:26
问题 I'm trying to read data from excel sheet that contains merged cells. When reading merged cells with openpyxl the first merged cell contain the value and the rest of the cells are empty. I would like to know about each cell if it merge and how many cells are merged but I couldn't find any function that do so. The sheet have empty others cells, so I can't use that. Will appreciate any help, I prefer openpyxl module but other modules can work,too. Thank you all! 回答1: You can use merged_cells

Git使用小结

廖雪峰的Git教程 一、 Git 仓库 仓库分为本地仓库和远程仓库,它们通过 秘钥 和 远程仓库地址 来建立连接。 A. 创建秘钥 SSH KEY (远程仓库:公钥,本地仓库:私钥) $ ssh-keygen -t rsa -C "youremail@example.com" 若 Git 只管理 GitHub 或 GitLab 中的一个,直接用上述命令即可 执行命令后,会在 ~/.ssh/ 目录下生成私钥 id-rsa 和公钥 id-rsa.pub 。 若同时管理两个,则需为其指定一下名称。 $ ssh-keygen -t rsa -C "youremail@example.com" id_rsa_lab $ ssh-keygen -t rsa -C "youremail@example.com" id_rsa_hub B. 提示:若上述命令在普通 cmd 界面执行,则可能会报错: 针对该问题,其实 git 相关命令都在 git bash 中执行即可 或者自行添加环境变量: 1. 找到Git/usr/bin目录下的ssh-keygen.exe 2. 如果找不到,可以在计算机全局搜索 3. 属性-->高级系统设置-->环境变量-->系统变量, 找到Path变量,进行编辑,End到最后,输入分号, 粘贴复制的ssh-keygen所在的路径,保存; 重新cmd,执行ssh-keygen
