Be aware that Python 3.7 final was released upstream only a couple of months ago and older versions of some Python libraries and frameworks like Django < 2.0, gevent < 1.3.6 are not fully compatible with the latest Python version. Python 3.7 brings also performance improvement, higher precision timing functions, typing enhancements and much more features and fixes, take a look at the official documentation for the complete list. Creating a trivial coroutine is now as simple as this: For example the new n() function removes the burden of creating the event loop explicitly. The asyncio standard library module has received many new features too. $ PYTHONBREAKPOINT=t_trace python3.7 script.py Or switch to use a debugger of your choice instead of the default PDB:
PYTHON RUNNER 3.7 CODE
You can simply ignore all the breakpoint() calls in your code by setting its value to zero: The main benefit of breakpoint() is that it is configurable via the PYTHONBREAKPOINT environment variable. It can be put anywhere in the code instead of import pdb pdb.set_trace() line. They aren’t examined at runtime.Īnother visible change is the new breakpoint() built-in function, which makes debugging your code smoother. If self.j is None and database is not None: self.j = database.lookup('j') Class definition and creation of the object, storing a bunch of data can be really easy now:įrom dataclasses import class C: i: int j: int = None database: InitVar = None def \_\_post\_init\_\_(self, database): In case you are bored of writing self.attribute = attribute in your _init_ methods all the time, you might like Data classes, documented in PEP 557. The latest major release of the language introduces many cool new features.
This multi purpose language is also a big player in the world of web development and that's why the batteries included infrastructure for building and deploying your Python projects is available on Platform.sh, and we've just added Python 3.7 to the list of supported versions. It doesn't matter if you do data science, develop a video game or you just need to write a quick-and-dirty script. We recommend you use -use-feature=2020-resolver to test your packages with the new resolver before it becomes the default.Īws-sam-cli 1.0.0 requires Flask~=1.0.2, but you'll have flask 1.1.2 which is incompatible.Īws-sam-cli 1.0.0 requires python-dateutil<2.8.1,~=2.6, but you'll have python-dateutil 2.8.1 which is incompatible.Python is one of the most popular programming languages of the last decade ( hey most of Platform.sh is written in Python!). This is because pip will change the way that it resolves dependency conflicts. I hope this can still help pinpoint the issue in case others experience the same (and I can add more information later if needed).ĮRROR: After October 2020 you may experience errors when installing or updating packages. I'm aware that I'm not providing a "minimum working example" here - I'm currently pressed for time. Successful run with 20200705.1 (after switching from python3.7 to python3.8 env): When requesting python 3.8 using setup-python, this issue does not occur (in this case, pip considers pyyaml not to be installed).
Note: This has been observed only when requesting a python environment (3.7) that was not yet installed on the runner. FileNotFoundError: No such file or directory: '/opt/hostedtoolcache/Python/3.7.8/圆4/lib/python3.7/site-packages/PyYAML-5.3.1-p圓.7-linux-x86_64.egg'
