I don’t know if it’s best practices or not, but if I also install python3-venv and python3.7-venv then everything works (this is tested on a fresh stock Debian buster docker image): % sudo apt install python3.7 python3-venv python3.7-venv % python3.7 -m venv py37-venv % . py37-venv/bin/activate (py37-venv) % Note that it also installs all of … Read more
It sure does work: from dataclasses import dataclass @dataclass class Test: _name: str=”schbell” @property def name(self) -> str: return self._name @name.setter def name(self, v: str) -> None: self._name = v t = Test() print(t.name) # schbell t.name = “flirp” print(t.name) # flirp print(t) # Test(_name=”flirp”) In fact, why should it not? In the end, what … Read more
Inspecting __annotations__ gives you the raw annotations, but those don’t necessarily correspond to a dataclass’s field types. Things like ClassVar and InitVar show up in __annotations__, even though they’re not fields, and inherited fields don’t show up. Instead, call dataclasses.fields on the dataclass, and inspect the field objects: field_types = {field.name: field.type for field in … Read more
Update: version 1.13 introduces Python 3.7 support The recent release candidate for the 1.13 version brings Python 3.7 support, in particular precompiled CPU wheels are also available for MacOS 10.11 and newer (link to 1.13.1). Install as usual: $ pip install tensorflow>=1.13 Original answer (outdated) tensorflow does not support Python 3.7 at the moment. The … Read more
Try uninstalling typing: pip uninstall typing or downgrading python to 3.6. There seems to be a problem with typing in 3.7 If after that you get: AttributeError: module ‘typing’ has no attribute ‘_ClassVar’ try pip uninstall dataclasses.

Write a function, which moves the window from dependent on a previous mouse position (start_x, start_y) and a mouse position (new_x, new_y) def move_window(start_x, start_y, new_x, new_y): global window_size_x, window_size_y window_x, window_y = eval(environ[‘SDL_VIDEO_WINDOW_POS’]) dist_x, dist_y = new_x – start_x, new_y – start_y environ[‘SDL_VIDEO_WINDOW_POS’] = str(window_x + dist_x) + ‘,’ + str(window_y + dist_y) # … Read more
No it won’t become redundant in Python 3.7 because OrderedDict is not just a dict that retains insertion order, it also offers an order dependent method, OrderedDict.move_to_end(), and supports reversed() iteration*. Moreover, equality comparisons with OrderedDict are order sensitive and this is still not the case for dict in Python 3.7, for example: >>> OrderedDict([(1,1), … Read more
pygame.key.get_pressed() is a function form pygame.key module. It returns a list of boolean values representing the state of every key on the keyboard. If you want to test if the SPACE key is pressed the you have to get the state of K_SPACE by subscription: keys = pygame.key.get_pressed() if keys[pygame.K_SPACE]: # […]

All credit for this goes to user han_solo, who left the answer as a comment, instead of as an answer: Instead of pip install stdlib_list –user use python -m pip install stdlib_list –user Replace stdlib_list with matplotlib or whatever the name is of the package you want.
