Kivy application does not work on Android

随声附和 提交于 2019-12-02 07:40:02
I want write simple application in Python for Android using kivy. Sadly when I start example code I see only splash screen and few second later application finish work. There is a huge problem with debugging because adb on Linux Mint does not detect my device. Can someone look at my code and tell my why? To build application I use buildozer. You can also see create_env script to check all dependencies are there. Best regards. Draqun EDIT: I started debugging my application. Conclusion: buildozer + python3 + kivy is a bad idea if I use kivy.uix.button.Button when text attribute is str than I

问题 This question already has answers here : How to access the type arguments of typing.Generic? (5 answers) Closed last year . I have some list types (coming from inspect.signature -> inspect.Parameter ) and I'd like to get to know the type of their elements. My current solution works but is extremely ugly, see minimal example below: from typing import List, Type, TypeVar TypeT = TypeVar('TypeT') IntList = List[int] StrList = List[str] # todo: Solve without string representation and eval def

落花浮王杯 提交于 2019-12-02 04:46:52
问题 I just updated Pycharm to the latest version and I've been having trouble with this error message. Basically, I can't turn off the error message that says "Python version 3.5 does not support variable annotations." My default and project interpreter is Python 3.6, and I don't even have Python 3.5 added in Pycharm, so any help with this would be much appreciated. Some pictures: Hope you guys can help and thank you in advance! Edit: Updated with one more picture of the Project Interpreter

Is it possible to identify TLS info. in requests response?

久未见 提交于 2019-12-02 03:58:29
I am using python's requests module. I can get the server's response headers and application layer data as: import requests r = requests.get('https://yahoo.com') print(r.url) My question: Does requests allow retrieving Transport layer data (the server's TLS selected version, ciphersuite, etc. ?). Here is a quick ugly monkey patching version that works: import requests from requests.packages.urllib3.connection import VerifiedHTTPSConnection SOCK = None _orig_connect = requests.packages.urllib3.connection.VerifiedHTTPSConnection.connect def _connect(self): global SOCK _orig_connect(self) SOCK =

Scheduling a python 3.6 script in using crontab/cron

与世无争的帅哥 提交于 2019-12-02 03:42:08
I'm just setting up a cron tab/job on my Cent OS developement server. Within my crontab I have the following. (Ignore the time setting, this was added about 15:32 UTC server time just to get the next scheduled run in). 34 15 * * * cd welcomeclient-0.0.5 && python3.6 main.py In the command line cd welcomeclient-0.0.5 && python3.6 main.py works fine. welcomeclient-0.0.5 is under root in the droplet, and python3.6 is in /usr/bin . Any suggestions? Try using absolute paths in your crontab command: 34 15 * * * cd /foo/bar/welcomeclient-0.0.5 && /usr/bin/python3.6 main.py or, assuming the main.py

PySide2 not updating QLabel text when asked

孤者浪人 提交于 2019-12-02 01:39:48
问题 I am upgrading from Python 2.7 to Python 3.6 and from PySide to PySide2.

It displays the widget, its label and the push button, but the push button does not change the text of the label. I added a print() to verify that the button is indeed calling the method associated with the click signal, and even added an update() to try to "encourage" it a
