问题 I have a relationship that is one to one between cage codes and duns numbers. I have set up my relationship that looks like, where I store a ForeignKey on each of the respective tables. class Cage(Base): __tablename__ = 'DimCage' id = Column(Integer, primary_key=True) cage = Column(String(8), unique=True, nullable=False) duns_id = Column(Integer, ForeignKey('DimDuns.id')) duns = relationship('Duns', uselist=False, back_populates='cage') class Duns(Base): __tablename__ = 'DimDuns' id = Column

问题 I have a complex object I'd like to build around a pandas DataFrame. I've tried to do this with a subclass, but appending to the DataFrame reinitializes all properties in a new instance even when using _metadata , as recommended here. I know subclassing pandas objects is not recommended but I don't know how to do what I want with composition (or any other method), so if someone can tell me how to do this without subclassing that would be great. I'm working with the following code: import

问题 So, I know about the sleep function, but it doesn't work how I expected it to work. If I do something like this: from time import sleep print('Something') sleep (10) print('Something') It works how (I think) it should (it prints one thing, waits and then prints the other one). But in my code it doesn't work like that. This is the whole code: from tkinter import * from time import sleep # Fenster window = Tk() window.title('Test') c = Canvas(window, height=450, width=800) c.pack() #

问题 I have used cx-freeze to make an executable file from my python 3 script. The issue is that apparently cx-freeze is having a hard time importing scipy scripts. I had to resolve other issues previously, e.g. adding the tcl library files manually. Anyway, my setup files is below: from cx_Freeze import setup, Executable import os os.environ['TCL_LIBRARY'] = "C:\\Users\\Gobryas\\AppData\\Local\\Continuum\\anaconda3\\tcl\\tcl8.6" os.environ['TK_LIBRARY'] = "C:\\Users\\Gobryas\\AppData\\Local\

问题 I am new to this area of using SOAP for NetSuite calls. Hence, I might be thinking completely incorrectly on how to solve the problem. Here is what I am trying to solve: - Language: Python+ Zeep - I want to move my application from email pass to Token based authentication. In Python I am able to generate all the parameters for TokenPassport. Here is where I am confused: I looked up some code on stack and noticed that folks were using client.service.login() method to login. This method takes

问题 I'm coding a game in python 3 using pygame latest version. I have a function that is intended to slowly fade the screen until it is totally black. It should do so by blitting a low-alpha black surface many times on the screen. But when I test it, it only blocks the game until the loop is finished. I suspect a problem with the alpha of black_surface. I've seen some questions on forums about fade in pygame, but none of them concerned fade directly in functions. Here is the code: def fade_to

问题 I rebuilt python 3.7 to get pyinstaller to work on Mac, and it seems to have deleted all my virtualenvs using 3.7.0. The .python-version files still exist, and they point at the location I would expect. But when I run 'pyenv virtualenvs' there's no python3 environments at all, and in the project directory, the python command doesn't work at all. 3.7.0/envs/some-scripts``` ```$ ls ~/.pyenv/versions/3.7.0/envs/some-scripts/bin/ activate chardetect macho_find netaddr pydoc pyi-makespec python3
