Ranked in these QuestionsQuestion Ranking
Pro Version control integration
PyCharm has CVS, Git, Subversion and Mercurial integration.
Pro Catches run-time information when running the code
PyCharm can leverage run-time information when running your application with the built-in debugger to figure out what types can possibly be passed to which functions, etc.
Pro One of the best autocompletion engines around
PyCharm has two types of autocompletion: structural completion and word expansion.
Both types of autocompletion work extremely well, have little to no problems and are quite fast even when loading suggestions on the go.
Pro Great pip support
PyCharm offers great pip integration. When opening a project it automatically checks for a
requirements.txt file in the root of the project. If it's found, it checks if all the libraries are available in the interpreter. If one or more libraries are missing, it issues a warning and asks whether you want to install any missing libraries.
Pro Free version available
There's a community edition (with limited features) that's free to use. You can also get a 30-day trial of the Professional edition.
Pro Excellent integration with debugging tools
All the debugging can be done inside the IDE. Breakpoints in the code can be added using keyboard shortcuts or the mouse. When the code is executed through the debugger a toolbar pops up with all the relevant context needed for the debugging process.
The whole process is smooth and painless and you don't even have to switch windows to do the debugging.
Pro Excellent refactoring support
There are many refactoring options including renaming and changing signature across entire projects. It also includes the an ability to preview changes before committing and exclude anything unwanted.
Pro Free student access to Professional Edition
With a valid .edu address students can register to use the Professional edition and enjoy all the perks of the full paid version for free.
Though it should be mentioned that the with the free student acess you cannot use PyCharm for any commercial purposes, even accepting donations for an open source project.
Pro Vim mode for people used to Vim commands
IdeaVim supports motion keys, insert mode commands, marks, registers, visual mode commands, vim regexps, key mapping, macros, digraphs, some ex and :set commands. You can find a full comparison in the IdeaVim reference manual.
Pro Great for navigating large codebases
PyCharm has amazing code navigation implementations. It supports both goto symbol and goto declaration. The former finds classes, variables, functions, etc by name. While the latter is used by moving the cursor on top of a symbol and by using the mouse or a keyboard combination it finds the declaration of that symbol and takes you there.
Both of these features are extremely helpful when consulting large code-bases and when trying to understand an API written by someone else.
Pro Automatically figures out what test to run based on the method the cursor rests at a given time
PyCharm, based on what method or class the cursor rests, can figure out what tests to run and perform them with a keyboard shortcut or two, without breaking up the flow and need to switch to a command line interface.
Pro Built-in Django support
Pycharm has excellent django support, from templating to management commands, it has it all.
Pro Easy to optimize code with built-in profiling tools
If you have a yappi profiler installed on your interpreter, PyCharm starts the profiling session with it by default, otherwise it uses the standard cProfile profiler.
Pro Remote debugging over ssh coupled with automatic deployment creates a streamlined workflow
The professional version allows remote debugging over ssh, which together with automatic deployment creates a streamlined workflow.
Pro Supports installing third party libraries
No need to go to the command line to download a new package, PyCharm has an easy system to browse, download, and update third party packages.
Pro Has a lot of plugins
PyCharm offers a high variety of plugins like Pylin, Mypy etc. covering all the above mentioned. Plus it has a built-in support to detect wrong formatted/named things (inspection).
Pro Amazing direct database integration
Pycharm supports SQLlite, PostgresQL, Mysql, etc out of the box and is integrated very nicely with Pycharm. Making database modifications could never have been easier as changing a cell value and committing the changes straight from pycharm.
Pro Sophisticated static analysis tools
Pro Free and open source
MacDown is a free and open source editor influenced by Mou. It's released under the MIT license.
Pro Real-time split-screen preview
MacDown's main view is split into two panels. The user types on the left and the Markdown is rendered on the fly in the right panel. This helps users to better understand the way they are formatting their document.
Pro Markdown previews can be customized with CSS
You can use a CSS file to customize the rendered output and the file preview you are working on will display the rendered Markdown with the custom CSS styling on top.
Pro Supports syntax highlighting in fenced code blocks
MacDown has syntax highlighting support for various languages when writing code in fenced code blocks.
Pro Good auto-completion
MacDown has a good built-in auto-completion engine for Markdown symbols.
Pro Support for GFM
Pro Ideal for day-to-day programmers' work and MarkDown novices alike
Using MacDown for the notorious README.md use case gets you going without reading any manual or requiring any configuration values. Think of it as a sort of TextEdit for MarkDown files. Thus its shortcomings - neither powerful nor versatile - turn out to be a PRO for novices trying to jump on the MarkDown bandwagon. Open its help and you'll immediately find yourself editing the MacDown's MarkDown help file, a MarkDown primer with some MacDown menus and configuration added.
Pro Linking between pages
Unlike a few other editors, MacDown lets you link between markdown pages.
Pro Tool bar with most used markdown shortcuts
This is especially useful for Markdown novices
Con Very high memory usage
Memory usage is usually anywhere around 1-2GB and possibly larger with larger projects
Con Not suitable to edit project's files written in other languages
There is a high variety of support for a lot of languages like markdown etc. Not for Java and so on, but it is a Python IDE.
Con Some relatively basic functionality requires paid license
Con Odd Autosave "feature", can't be disabled fully
PyCharm automatically saves your files for you, always, without telling you. You can't disable this. There's a way to indicate if a file has been modified via an indicator in the tab (not enabled by default - why?).
If you exit it won't ask you if you want to save the modified file. Totally unintuitive and contrary to all other established workflows. It's ok to try something new, but give users the option to have the "normal" behaviour of any other IDE/editor out there. Can be a deal breaker for those that need to know/have control over when they save their files. (PyCharm offers a history to undo the automatic save, but why force a user to undo something with extra steps that shouldn't have happened in the first place?)
Con Not possible to run scripts in a single console
Con It cannot reindex on the fly packages installed from git source
If you've installed a package with the command:
pip install -e git+https://email@example.comfirstname.lastname@example.org#egg=package
you have two options available to make PyCharm update/see it:
- restart PyCharm
- invalidate caches
Con Asinine licensing scheme
JetBrains licensing, especially if you have multiple products, is a blocker. You just can't have a fixed line-item price (for departmental budgeting) for their licenses.
Con Vim mode is limited
Con Rendering is awful
Con Little native desktop integration
If you use Linux with Gnome or KDE, PyCharm does relatively little to integrate into your local desktop environment
Con Sometimes all autocomplete stuff dies with over 9k Java exceptions with no visible reason
Con Not very versatile
MacDown is not very powerful or versatile. It's not customizable or extendable. This is what makes it so simple, but it's not for people who want more from their tools.
Con Frequently fails to update the display and/or flat out hangs
Must often restart MacDown.
Con The Markdown preview is rather heavy on the CPU
The Markdown preview needs a lot of resources to keep rendering on-the-fly after each keystroke. A single keystroke in the editor panel may trigger up to 5 seconds of max-CPU usage.
