Using PyCharm I want to show plot extra figure windows

阅读更多关于 Using PyCharm I want to show plot extra figure windows

问题 After installing Anaconda3 & PyCharm in new PC, I tried to test the same code as uploaded here And I got a window like this. But usually I use the plot window like this format (from google image search) I think the first view is useful for checking all of the plots, but I'm already used to the second version, separated plot figure from PyCharm console, and I can use the control panel. So I want to use PyCharm as in the second picture. How can I change my PyCharm settings to use the second

Get PyCharm to know what classes are mixin for

阅读更多关于 Get PyCharm to know what classes are mixin for

问题 Our application has set of complex form wizards. To avoid code duplication I created several mixins. The problem is that PyCharm highlights mixin methods with Unresolved attribute refference error. This is correct as object does not have such methods. But I know that this mixin will be used only with special classes. Is there any way to tell this info to PyCharm? For now I use such approach: class MyMixin(object): def get_context_data(self, **kwargs): assert isinstance(self,

PyCharm IDE how can I change font size with out zooming with mouse scroll

阅读更多关于 PyCharm IDE how can I change font size with out zooming with mouse scroll

问题 As title says, how can I change the font size in editor by some value. I like the scrolling thing, but the problem is I have to scroll again and every time I open an IDE again. I found the settings for changing the value of the font size, but it's disabled. Do I have to pay for that feature ? 回答1: version 2017.1 and older -- Settings/Preferences | Editor | Colors & Fonts | Font since 2017.2 -- Settings/Preferences | Editor | Color Scheme | Color Scheme Font I found the settings for changing

When I assign a list to variable why Pycharm give me a prompt that is “this list creation could be rewritten as a list literal”?

阅读更多关于 When I assign a list to variable why Pycharm give me a prompt that is “this list creation could be rewritten as a list literal”?

问题 I am a Python beginner and have a puzzle. When I write code like this: lst = [1, 2, 3, 4] Pycharm give me a prompt that is "this list creation could be rewritten as a list literal". But if it's replaced by lst = list([1, 2, 3, 4]) Pycharm doesn't say anything. Who could tell me why? Is this code like lst = [1, 2, 3, 4] legal in Python? Can I ignore prompt? 回答1: Check your code to make sure you don't have lst somewhere else as lst=[] . If you type the following: lst= [] # more code lst = [1, 2

mac安装完anaconda后,环境变量设置

阅读更多关于 mac安装完anaconda后,环境变量设置

环境：MacOS Sierra 10.12.3；PyCharm Community Edition 2017.1 1. 安装Anaconda：从 https://www.continuum.io/downloads/ 下载 python 2.7 version中的图形界面版本或者命令行版本（根据自己的需要），然后在terminal中执行命令bash Anaconda2-4.3.1-MacOS-x86_64.sh 2. 这个时候在终端里面输入conda 是无法识别这个这个命令的，需要添加环境变量。在terminal中执行以下命令（需要根据自己anaconda的安装路径作出调整）： export PATH=~/anaconda2/bin:$PATH 这时在terminal里面输入conda就可以给出命令信息了，这样可以检验你的conda是不是可以用。来源： oschina 链接： https://my.oschina.net/u/4350688/blog/4272065

How to make PyCharm Python console work with code?

阅读更多关于 How to make PyCharm Python console work with code?

问题 I am new to PyCharm (coming from IDLE) and still trying to understand how it works. I'm running PyCharm Professional 2019.3.1 on MacOS Mojave. What I'm asking is that when I run a code in PyCharm, the variables and data aren't stored in the Python console - it remains completely blank and I have to separately write in the console. For instance, in IDLE: When I write x = 2 in my program and execute it, I can browse and manipulate the value of x in IDLE's console (by entering > x = 3 , > x = 0

vs code python 关于无法找到文件路径的问题 No such file or directory

阅读更多关于 vs code python 关于无法找到文件路径的问题 No such file or directory

之前习惯用pycharm来开发python程序，但是pycharm打开的速度实在是太感人了，所以想转用vscode编辑器来写python，毕竟python作为一个脚本语言，用编辑器写也不会有太大的问题。但是在vscode下写python程序的时候以为发现一个问题，在pycharm下能正常使用的程序，在vscode下就无法正常使用了，其中的一个问题就是会出现 FileNotFoundError: [Errno 2] No such file or directory: 'xxx.xxx' 首先我的文件路径是这样的。文件路径.png 现在test2.py里面有这行代码，也是这行代码报错。 file = open ( 'data_baidu.txt' , 'r' , encoding = 'utf-8' ) 找了一下原因，发现如果直接在split_test文件目录下用命令行运行python test2.py不会有问题，但是在其他目录下运行就会报上面的FileNotFoundError的错误。用命令行运行代码这样一来，谜题解决了，pycharm运行python程序的时候是在相应的文件目录下运行的，而vscode是在相应的工程目录下运行的。可以看看vscode里面的launch.json的配置，这里的${file}的意思是vscode所打开的文件夹的路径。 Paste_Image
