Best practice is subjective, but the most common practice is to stick to PEP8. I definitely don’t suggest creating dictionaries every time you want to call a function with named arguments. That’s quite wasteful. I don’t see why your original some_func call wouldn’t work. I definitely break my function calls into lines if they get … Read more
Quoting PEP-8’s Programming Recommendations section, For sequences, (strings, lists, tuples), use the fact that empty sequences are false. Yes: if not seq: if seq: No: if len(seq) if not len(seq) Since empty sequences are Falsy in Python, >>> bool([]) False >>> bool(()) False you can simply use if not as mentioned in the PEP-8. Note: … Read more
Either use setup.cfg for single project or change your user settings for all py files. { “python.linting.pycodestyleEnabled”: true, “python.linting.pycodestyleArgs”: [ “–ignore=E501” ] } Before October 2019 all pycodestyle settings were named pep8: { “python.linting.pep8Enabled”: true, “python.linting.pep8Args”: [ “–ignore=E501” ] }
Just figured out: def long_string(): “”” Returns a string which is wider than the recommended PEP8 linewidth >>> print long_string() 01234567890123456789012345678901234567890123456789012345678901234567890\ 12345678901234567890123456789 “”” return ‘0123456789’ * 10 Hope that helps somebody else out.
Just add another line between your function definitions : 1 line : 2 lines:
PEP8 says to avoid “More than one space around an assignment (or other) operator to align it with another” and “never use more than one space” around math operators, but I don’t follow this. I often add “extraneous whitespace” when neighboring lines are related or very similar, but not quite the same: search_start = (f … Read more
Make sure you’ve the module pycodestyle or flake8 to be able to check your code against the style guides. Then enable the magic function by using the pycodestyle_magic module (github repo): pip install flake8 pycodestyle_magic first load the magic in a Jupyter Notebook cell: %load_ext pycodestyle_magic and then turn on the magic to do compliance … Read more
I don’t think there’s an extension directly in Colab. What you could do, though, is to download your notebook, run pip install -U nbqa nbqa black notebook.ipynb and then reupload your (now formatted) notebook to Colab disclaimer: I’m the author of nbQA UPDATE: as of version 21.8b0, black runs directly on notebooks, no third-party tool … Read more
The logging module was developed by a separate company in 2001, and was heavily based on Log4j. As such it follows the naming conventions the original author picked, which mirror the Log4j choices; the latter has a getLogger() method too. Not until a year later did PEP 282 propose to add it to the standard … Read more
PyCharm is built on top of IntelliJ. IntelliJ has a default line length of 120 characters. This is probably because you can’t fit a common Java name like: @annotated public static MyObjectFactoryFactory enterpriseObjectFactoryFactoryBuilderPattern { in a mere 80 character line. (I’m poking fun, but Java names do tend to be longer by convention). The pep8 … Read more
