Spyder 常用快捷键总汇

由 无人久伴 提交于 2020-01-16 12:37:37
1、 Spyder是anaconda中一个python的集成开发环境，其优点是模仿Matlab环境，可以方便的查看和修改数组取值。不得不说anaconda是一个好东西，学python的可以用用，里面集成了好多开发环境，省去了我们安装软件等各种问题。只需你安心的学习相关技术即可。这一章节主要是对anaconda中的Spyder所常用的快捷键做一总汇： 　　F5:运行 　　F11:全屏 　　Ctrl + 1: 注释/反注释 　　Ctrl + 4/5: 块注释/块反注释 　　Ctrl + L: 跳转到行号 　　Tab/Shift + Tab: 代码缩进/反缩进 　　Ctrl ＋I：显示帮助 　　Tab：空行前是代码缩进；在输入一个字母后，按Tab健会自动补全或者代码提示。 　　Shift+Tab：撤销代码缩进 2. 可以在Ipython Console输入变量进行快速验证，类似matlab 3.快捷键查看方法：Tools-->Preferences-->Keyboard Shortcut 可以查看所有快捷键 　　 4.spyder如何调节注释颜色：——》在tools菜单里面Preferences菜单里 来源： https://www.cnblogs.com/cjtds/p/12200534.html

在jupyter notebook和spyder切换python环境

由 谁说胖子不能爱 提交于 2020-01-16 01:55:06
有时需要在不同环境下运行jupyter notebook和spyder，如何在这两个编译器里切换python环境呢？ 1. jupyter notebook切换python环境 这里以切换torch环境为例。 1.1 安装nb_conda 首先确认一下你的notebook里是否有conda这一个版块： 没有的话需要进行安装： 进入conda prompt，输入： conda install nb_conda 1.2 切换环境 安装完毕后重启Jupyter notebook就可以看到，进入该标题下： pytorch这个环境还没有对勾，就说明还不能切换到这个环境，在左下方搜索ipykernel包，进行安装 再重启jupyter notebook后，右上角新建中就可以选择我创建的pytorch环境了： 2. jupyter notebook切换python环境 首先在conda prompt中进入要切换的环境： 之后输入： conda install spyder spyder 就可以了 来源： CSDN 作者： YaqiYuki 链接： https://blog.csdn.net/weixin_43326692/article/details/103985350

问题 i don't really know why, but Spyder is not able to show lists or arrays in the variable explorer anymore. Do you have the same problem, any fixes? I have that problem on two computers. Example: CSV = [] for x in os.listdir(location): if x.split(".")[-1] =="CSV": CSV.append(location+x) CSV = np.array(CSV) Thank you very much! 回答1: Menu (Tools->Preferences->Variable Explorer) Shortcut (Ctrl+Alt+Shift+P) Disable all the filters 回答2: Just make sure "Exclude capitalized references" in "Tools-
