Workable alternative to “Presentation Mode” in Intellij and Pycharm

阅读更多关于 Workable alternative to “Presentation Mode” in Intellij and Pycharm

问题 As detailed in this YouTrack issue https://youtrack.jetbrains.com/issue/PY-40008 Presentation Mode is basically a one-way ticket: you can check in but you just can't leave . One of the "misses" of returning to "normal" mode is that only the Editor panel is displayed: the Explorer, Debugger, etc. are all invisible. That's a hassle to rectify in real time when presenting to a group of people. When I am actually giving presentations that include code snippet walk-throughs going back and forth

点击上方“ Python爬虫与数据挖掘 ”，进行关注回复“ 书籍 ”即可获赠Python从入门到进阶共10本电子书今日鸡汤近乡情更怯，不敢问来人。一、前言大家好，我是崔艳飞。接到项目求助，需要对上千个文件夹中的文件进行压缩处理，并要删除源文件，只保留压缩后的压缩文件，数据量大，手动完成耗时耗力，用Python处理再合适不过了。二、项目目标批量对文件夹的内容进行压缩处理，满足客户要求。三、项目准备软件：PyCharm 需要的库：os， shutil，zipfile 四、项目分析 1）如何读取源文件？利用OS库，获取文件夹名list，利用for循环，轻松拿到要压缩的源文件。 2）如何进行压缩处理？利用zipfile库中的zipfile.ZipFile()对获取到的文件进行压缩处理。 3）如何删除源文件？先利用os库的remove()删除文件，再利用shutil库的rmtree()删除空文件夹。五、项目实现 1、第一步导入需要的三个库 import os as os import shutil import zipfile 2、第二步定义删除文件函数和压缩文件函数 def del_ (rootdir) : filelist = [] filelist = os.listdir(rootdir) # 列出该目录下的所有文件名 for f in

问题 Is it possible to have a keyboard shortcut to move the caret from editor to console and back in pycharm? I can switch the focus between editor and console using CTRL+TAB, but that doesn't allow me to start typing in the console unless I click in it. I am using the linux community distribution. 回答1: I'm on MacOS and PyCharm 2018.2. Doing Ctrl+Tab+P opens up console and focuses on it so I can immediately start typing. Update: You can also set your own key map: Tool Windows/Python Console .
