NameError: name 'sys' is not defined appears with buildozer

I tried to made an Android app with the Package tapo-plug, kivy and buildozer, but the app crashes directly after opening it. I never did something like this before. This is the Error-message send by my phone:

I already set tapo-plug,Crypto,PyCryptodome,pyjwkest,pycrypto as requirements.
This is my first time doing something like this.
This is the script-part the error occurs in:

It's hard to guess what cause your issue without minimal reproductable sample. I made simple Kivy project, it works without issues under Windows and Android.
buildozer.spec requirements:
requirements = python3,kivy,pycryptodome,pkcs7,Crypto,tapo-plug,requests,urllib3,charset_normalizer,chardet,idna

MAP++ on Windows with Python

I am trying to run MAP++ on Windows using the python driver. I downloaded the package from https://bitbucket.org/mmasciola/map-plus-plus/src/master/. When running it, I’m getting the following error:
AttributeError: function 'map_offset_fairlead' not found
I’ve tried Python 3 and 2, both give errors. In mapsys.py I’m using
lib = cdll.LoadLibrary("map_x64.dll")
and I have the map_x64.dll stored directly in the folder containing the mapsys.py script. Maybe I have an old version of the dll? Where do I get most recent one?

error trying to use marshmallow_dataclass

I am trying to use marshmallow_dataclass in a python (3.9) test in pycharm to try it (marshmallow_dataclass) out and get an error.
Not sure what I am doing wrong. I have installed marshmallow_dataclass (8.1.0)
I have so far been successful in using marshmallow (3.8.0) and marshmallow_oneofschema (2.1.0) so far
(new to python but not programming)
Code is:
import marshmallow_dataclass
import unittest
class Tests(unittest.TestCase):
def test_serialize(self):
print("Hello")
Error is:

I hit similar error on python 3.9 alpha release (3.9.0a5), I am not sure the version of typing_extensions.py in your environment (maybe it is v3.7.4.3 ?).
The root cause is that :
the function TypeAlias() is decorated directly with the class _TypeAliasForm, which is subclass of typing._SpecialForm in python stardard library
typing._SpecialForm.__init__() in your python environment has extra argument doc , since the class _TypeAliasForm is a decorator for TypeAlias(), Python couldn't provide extra argument doc when instantiating _TypeAliasForm on decorating process.
In short, your typing_extensions.py is out of sync with your python interpreter, see the source code for detail:
TypeAlias() and _TypeAliasForm class .
typing._SpecialForm.__init__() in python 3.9.0a5
typing._SpecialForm.__init__() in python 3.9.0a6
It seems that the issue happens from python 3.9.0a1 to 3.9.0a5, so the solutions are :
upgrade your python to final release version
if you are not allowed to upgrade python for some other reasons, maybe you can monkey-patch typing._SpecialForm , here is the example for monkey-patching :
from typing import _SpecialForm
origin_getitem = _SpecialForm.__getitem__
def patch_init(self, name, doc=None):
if doc is None and callable(name):
if hasattr(name, '__doc__'):
doc = name.__doc__
self._name = name
self._doc = doc
def patch_getitem(self, parameters):
item = None
if callable(self._name):
item = self._name(self=self, parameters=parameters)
else:
item = origin_getitem(self=self, parameters=parameters)
return item
if not hasattr(_SpecialForm.__init__, 'patched'):
_SpecialForm.__init__ = patch_init
setattr(_SpecialForm.__init__, 'patched', True)
if not hasattr(_SpecialForm.__getitem__, 'patched'):
_SpecialForm.__getitem__ = patch_getitem
setattr(_SpecialForm.__getitem__, 'patched', True)

Script works on PyCharm but not in terminal

I am working on some API script in Python, it takes one argument and returns JSON. I am using BrawlStats library (https://github.com/SharpBit/brawlstats). It works very well in PyCharm but doesn't work in terminal, I have no idea why, I tried few suggestions like running "pip install" in script directory but it still doesn't help. I ma trying to run the script using PHP but it returns the same error as terminal: https://gyazo.com/afac3d7c7e50b4c4925ec767dc5457b2 + https://gyazo.com/5a55668e5e4cd005a64dd5c702043b98. Help would be really appreciated, I am stuck and I don't know how to fix it :/
Code:
import brawlstats
import json
import sys
client = brawlstats.Client("***")
def OMEGA(LUL):
player = client.get_profile(LUL)
xxDD = {
"tag": player.tag,
"name": player.name,
"avatar": player.avatar_url,
"trophies": player.trophies,
"victories": player.victories,
"level": player.exp_level
}
print(json.dumps(xxDD))
return json.dumps(xxDD)
print(sys.argv[1])
OMEGA(sys.argv[1])
and here is error when I run it using PHP/terminal:
Traceback (most recent call last):
File "C:/xampp/htdocs/main.py", line 23, in <module>
OMEGA(sys.argv[1])
File "C:/xampp/htdocs/main.py", line 8, in OMEGA

File "C:\Users\Krzysztof\AppData\Local\Programs\Python\Python36\lib\site-packages\brawlstats\core.py", line 147, in get_profile

File "C:\Users\Krzysztof\AppData\Local\Programs\Python\Python36\lib\site-packages\brawlstats\core.py", line 124, in _get
with self.session.get(url, timeout=self.timeout, headers=self.headers) as resp:
AttributeError: __enter__
Last thing, here is output when I run it using PyCharm:
{"tag": "CP0GU982", "name": "flick", "avatar": "https://fourjr.github.io/bs-assets/player_icons/28000000.png", "trophies": 6, "victories": 1, "level": 1}

Invalid syntax while running test on Travis

I'm having a problem with Travis on every commit. My tests work on local but on Travis I get this error:
Traceback (most recent call last):

SyntaxError: invalid syntax
Here is the code where that line is:
def remove_accent_marks(text):
good_accents = {
u'\N{COMBINING TILDE}',
u'\N{COMBINING CEDILLA}'
}
return ''.join(c for c in unicodedata.normalize('NFKD', text)
if unicodedata.category(c) != 'Mn' or c in good_accents)
I have no idea about what is the problem because as I've said, all test are working in local. Here is my .travis.yml file:
language: python
python:
- "3.2"
- "3.3"
- "3.4"
script: python -m unittest discover
Any idea?

The u'...' syntax in Python 3 is only supported in Python 3.3 and up.
The u prefix is only there to support polyglot Python code (supporting both 2 and 3), and can be safely removed if you don't need to support Python 2.
If you need to support both Python 2 and 3.2, you'll have to use a different approach. You could use a from __future__ import to make all string literals in Python 2 produce unicode string objects; this applies per module:
from __future__ import unicode_literals
def remove_accent_marks(text):
good_accents = {
'\N{COMBINING TILDE}',
'\N{COMBINING CEDILLA}'
}
The strings will be treated as Unicode in both Python 2 and 3.
Or you could create your own polyglot function:
import sys
if sys.version_info[0] < 3:
u = lambda s: unicode(s.replace(r'\\', r'\\\\'), "unicode_escape")
else:
u = lambda s: s
and use that on all your Unicode strings:
def remove_accent_marks(text):
good_accents = {
u('\N{COMBINING TILDE}'),
u('\N{COMBINING CEDILLA}')
}
or you can use the six library to produce that bridge for you:
import six
def remove_accent_marks(text):
good_accents = {
six.u('\N{COMBINING TILDE}'),
six.u('\N{COMBINING CEDILLA}')
}
