可以使用别的软件代替Anaconda么?
我们以后的课程必须用Anaconda python呢?还是其他软件如果可以运行python和jupyter notebook就可以呢?

Question for adding and removing a string for each line from a txt file
老师因为今天QA session有事所以就来这里问了,因为自己没什么coding基础所以就想到什么就会自己去试试能不能用code解决;问题如下
Question 1:
单纯好奇为什么这里elif会比else快
Question 2:
不知道code的问题出在哪里,或者老师有哪些推荐更合理的code来remove string
Question 3:
不知道下面的code问题出在哪里
with open('1.txt', 'r') as f:
file_lines = [''.join(['#', x.strip(), '\n']) for x in f.readlines() if not line.startswith("#")]
with open('1.txt', 'w') as f:
f.writelines(file_lines)
谢谢^

这次的作业Pull requests在上次的homework1上了
我点Pull requests的时候,直接就在homework1上更新了,我现在把名字改成homework2了
The pandas book you mentioned in class
Hi Emma,
I'm curious what's the name of the pandas book you mentioned in the class that has a red cover and you said you have read through the whole book. Thanks.
And what other books you would recommend for data scientists overall, not only for data analyst but other parts like machine learning, coding, or statistic?
Thanks.
Confused about the branches
Hi Emma,
I got a bit confused about what I should be looking for in each branch. For instance, class01 branch has class 01, class 02 also has class01, class 04 has class01, class02, and class03. So is each branch an update from the last one? Does this mean I always look for the latest branch, e.g., class05, since it has all the contents from branches class01-04?
Also, there seems to be a new fold in the master branch that has the same content as other branches, should I just ignore branchs class01 - class05?
Thanks
If语句的判定
感觉还是有很多同学对于if
语句的判定和variable的boolean值有一些问题,推荐看一下这个documentation:
https://docs.python.org/3/library/stdtypes.html#truth-value-testing
图形操作界面的git (pull/stage/commit/push)-- SourceTree
同学们好,以下是我个人觉得比较方便的一个git 工具,可以非常直观方便地完成git 相关的操作。而且比较符合我们使用程序的习惯,只需要鼠标点击即可。
这款软件的名字叫做SourceTree. 下载链接如下:https://www.sourcetreeapp.com/.
首次使用我们需要将我们个人github 上的repo clone 下来,我们点击Clone
如上图, 第一栏我们输入github上自己repo 的clone 链接,第二栏是我本地新创建的一个文件的路径。
左边菜单栏里的“remote” 显示的就是我github上所有的branch,双击其中任何一个之后,本地的环境就会自动check out 对应的branch。如图所示,我双击了homework1 之后,我在本地文件做的任何改动都会最终对应到“homework” 这个branch 上。
当你做出任何改动的时候,sourcetree 就会侦测到,如下图,我创建了一个test.txt 的文件
我们只要相应地点击stage all, commit, push. 就可以将这一个改动,推送到我的github repo上
。
当我们的remote repo 有任何改动,然而我们的本地文件夹并没有跟上的时候,我们只需要点击“Pull” 即可。
希望上面的内容能对大家有所帮助
非默认path 用命令行不能打开jupyter notebook
win10用户,在非默认path 用命令行打开jupyter notebook的话会提示
'jupyter' is not recognized as an internal or external command,
operable program or batch file.
system path已经添加了
