问题 For school i am writing a small program for a rankinglist for a game. I am using dicts for this, with the name of the player as keyname, and the score as keyvalue. there will be 10 games, and each game will have an automatic ranking system which i print to file. ive already managed to code the ranking system, but now im facing a bigger challange which i cannot solve: I have to make an overall ranking, which means someplayername can be in several contests with several scores, but i need to

How to merge two pandas DataFrames based on a similarity function?

问题 Given dataset 1 name,x,y st. peter,1,2 big university portland,3,4 and dataset 2 name,x,y saint peter3,4 uni portland,5,6 The goal is to merge on d1.merge(d2, on="name", how="left") There are no exact matches on name though. So I'm looking to do a kind of fuzzy matching. The technique does not matter in this case, more how to incorporate it efficiently into pandas. For example, st. peter might match saint peter in the other, but big university portland might be too much of a deviation that we

What's the fastest way to merge multiple csv files by column?

守給你的承諾、 提交于 2020-04-08 06:41:03
问题 I have about 50 CSV files with 60,000 rows in each, and a varying number of columns. I want to merge all the CSV files by column. I've tried doing this in MATLAB by transposing each csv file and re-saving to disk, and then using the command line to concatenate them. This took my computer over a week and the final result needs to transposed once again! I have to do this again, and I'm looking for a solution that won't take another week. Any help would be appreciated. 回答1: [...] transposing

场景: 用户UserA修改了文件File1,用户UserB也修改了文件File1并成功merge到了服务器上,而UserA和UserB改动了同一个代码块,当UserA拉取代码时git无法merge此改动,就会出现如下错误提示: $ git pull Updating 88b0e2d..af4b152 error: Your local changes to the following files would be overwritten by merge: xxxxx/TuningPool.java Please, commit your changes or stash them before you can merge. Aborting 1、先将本地修改存储起来 Git提供了一个stash功能,可以把当前工作现场“储藏”起来,等以后恢复现场后继续工作 $ git stash 用git stash list可以看到保存的信息,其中stash@{0}就是刚才保存的标记。 $ git stash list stash@{0}: WIP on dev: 88b0e2d Control the thread number 2、pull内容 暂存了本地修改之后,就可以pull了。 $ git pull 3、还原暂存的内容 工作现场还在,Git把stash内容存在某个地方了

git 标签

打标签 同大多数 VCS 一样,Git 也可以对某一时间点上的版本打上标签。人们在发布某个软件版本(比如 v1.0 等等)的时候,经常这么做。本节我们一起来学习如何列出所有可用的标签,如何新建标签,以及各种不同类型标签之间的差别。 列显已有的标签 列出现有标签的命令非常简单,直接运行 git tag 即可: $ git tag v0.1 v1.3 显示的标签按字母顺序排列,所以标签的先后并不表示重要程度的轻重。 我们可以用特定的搜索模式列出符合条件的标签。在 Git 自身项目仓库中,有着超过 240 个标签,如果你只对 1.4.2 系列的版本感兴趣,可以运行下面的命令: $ git tag -l 'v1.4.2.*' v1.4.2.1 v1.4.2.2 v1.4.2.3 v1.4.2.4 新建标签 Git 使用的标签有两种类型:轻量级的(lightweight)和含附注的(annotated)。轻量级标签就像是个不会变化的分支,实际上它就是个指向特 定提交对象的引用。而含附注标签,实际上是存储在仓库中的一个独立对象,它有自身的校验和信息,包含着标签的名字,电子邮件地址和日期,以及标签说明,标 签本身也允许使用 GNU Privacy Guard (GPG) 来签署或验证。一般我们都建议使用含附注型的标签,以便保留相关信息;当然,如果只是临时性加注标签,或者不需要旁注额外信息

Git 的标签管理。跟大多数的 VCS 工具一样,git 也有在历史状态的关键点“贴标签”的功能,一般人们用这个功能来标记发布点(例如’v1.0′)。 列出git中现有标签 要想列出git中现有的所有标签,输入’git tag’命令运行即可: $ git tag v0.1 v1.3 这个列表是按照字母表顺序给出的,其实排名先后跟重要程度没有直接联系。 当然,你也可以按照特定表达式搜索某些标签。假如在一个 git 仓库中有超过 240 个标签,而你只想得到 1.4.2 序列的标签,那么你可以: $ git tag -l v1.4.2.* v1.4.2.1 v1.4.2.2 v1.4.2.3 v1.4.2.4 创建标签 在 git 中有两种最主要的标签–轻量级标签(lightweight)和带注释的标签(annotated)。轻量级标签跟分枝一样,不会改变。它就是针对某个特定提交的指针。然而,带注释的标签是git仓库中的对象。它是一组校验和,包含标签名、email、日期,标签信息,GPG签名和验证。一般情况下,建议创建带注释的标签,这样就会保留这些信息,但是如果你只是需要临时性标签或者某些原因你不想在标签中附带上面说的这些信息,lightweight标签更合适些。 带注释的标签 在git中创建带注释的标签非常简单,在运行’tag’命令时加上-a就可以了。 $ git tag -a v1
