When comparing PyCharm vs Visual Studio with the Python Tools extension, the Slant community recommends PyCharm for most people. In the question“What are the best Python IDEs or editors?” PyCharm is ranked 1st while Visual Studio with the Python Tools extension is ranked 33rd. The most important reason people chose PyCharm is:
PyCharm has CVS, Git, Subversion and Mercurial integration.
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 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 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 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 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 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 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 Built-in Django support
Pycharm has excellent django support, from templating to management commands, it has it all.
Pro Sophisticated static analysis tools
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 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 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 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 Autocompletion based on variable types
Has smart autocompletion based on variable types
Pro Cloud storage through VS Online
Your Visual Studio Online account gives you a place to store your code, backlog, and other project data with no servers to deploy, configure, or manage.
Pro Web based interface to track project progress
In agile development teams one really needs features such as product backlogs where you can assign features to team mates and track their progress on them. VS provides a web based interface for you to track your team's complete progress on the project.
Con Very high memory usage
Con Does not support inline plots
Spyder supports the inline plot function of matplotlib, not the case for PyCharm.
Con Rendering is awful
Con Vim mode is limited
Con Not suitable to edit project's files written in other languages
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 Assinine licensing scheme
JetBrains licensing, especially if you have multiple products, is a blocker. You just can't a fixed line-item price (for departmental budgeting) for their licenses.
Con Can not be integrated with external linters, like Pylint, Flake8, etc.
Sublime Text has SublimeLinter, Vim has Syntastic, PyCharm has nothing.
Con Not possible to run scripts in a single console
Con Windows only
Visual Studio is only available on Windows, though there is now a cross-platform derivation of Visual Studio named Visual Studio Code. It is has less features and is more of a code editor than an IDE.
Visual Studio is a proprietary software.
