python-3.7

问题 In order to split a large class into multiple files, this answer, recommends using the import command at the class level to load methods whose definitions can be moved to other modules. As a minimal example, class_def.py : class C: from _methods import m _methods.py : def m(self): return "hello" Normally, most IDEs which feature code completion will recognize functions which are defined in some class as bound methods, and self will automatically be recognized as having the type of the class

问题 From What’s New In Python 3.7 we can see that there is new math.remainder. It says Return the IEEE 754-style remainder of x with respect to y. For finite x and finite nonzero y, this is the difference x - n*y , where n is the closest integer to the exact value of the quotient x / y . If x / y is exactly halfway between two consecutive integers, the nearest even integer is used for n . The remainder r = remainder(x, y) thus always satisfies abs(r) <= 0.5 * abs(y) . Special cases follow IEEE

问题 I started studying machine learning. I am following a google tutorial, but I face this error and the answers that I have found haven't work in my code. I'm not sure but it seems that the Python version has changed and doesn't use some library anymore. This is the error: [0 1 2] [0 1 2] Warning (from warnings module): File "C:\Users\Moi\AppData\Local\Programs\Python\Python37-32\lib\site-packages\sklearn\externals\six.py", line 31 "(https://pypi.org/project/six/).", DeprecationWarning)

问题 When trying to deploy my fastapi python service (on App Engine), I'm running into the following error in the deploy step: ERROR: gcloud crashed (OSError): [Errno 2] No such file or directory: '/workspace/env/bin/python3.7' I'm starting the deploy/build from my local machine with the following command: gcloud builds submit --config config/cloudbuild/deploy.yaml --project $_PROJECT . Am I doing something wrong, or could it be something wrong with the gcloud builder? I've tried with both google

问题 I want to define some functions named 'test_[strings]' to use for pytest, like : testfiles = ['first.py', 'second.py', 'third.py', ... ] def test_first(): test_code def test_second(): test_code def test_third(): test_code ... The test code is all same, so I think it'll be much simpler if I can define pytest functions by using something like for loop : for filename in testfiles : func_name = 'test_'+filename.rstrip('.py') def func_name() : test_code Is this possible in python3? And if it is,

问题 Currently we are working on an application which is trying to calculate the travel time of a route from a to b, using the 2.db.transport.rest API. Unfortunatly we are receiving timestamps with a timezone offset from that API, such as +01:00 . What we need is a timezone offset without the : , so +0100 . The following example gives an error on Linux, using Python 3.6.7: from datetime import datetime datetimestring = "2019-01-19T15:13:00.000+01:00" datetime.strptime(datetimestring, '%Y-%m-%dT%H:
