Post: RE: Dealing with multiple context managers

Thanks, so they can essentially share a context manager. Maybe I can also use asynccontextmanager to get the structure I want.

    Thread: Dealing with multiple context managers
Post: RE: Dealing with multiple context managers

Thanks for your suggestion nilamo. So the unavoidable seems to be that you have to pick one master context and embed all the lesser contexts in it? I will give it a try but I think it will be difficul...

    Thread: Storing chart objects in a dictionary
Post: RE: Storing chart objects in a dictionary

chart = n will make chart point to the key(s) of the dictionary which is a string, but you want the value associated with that key. Try this: chart = d[n]

So len_cumsum = len(self.data[dest+'_cumsum'])will ask whatever object is associated with dest+'_cumsum' for its length. len_cumsum = len(self.data[dest+'_cumsum'][:])will recreate the list inside le...

You are brilliant! A small test: >>> a = {'as': [1,2,3,4,5,6]} >>> a {'as': [1, 2, 3, 4, 5, 6]} >>> len(a['as']) 6 >>> len(a['as'][:]) 6I will see if I can figure o...

return instead of yield would exit the function and forget about a and b (try it!). yield will return a value while retaining the state of the function in memory until the next time fib() is called. I...

    Thread: Methods of running a script on Linux distro
Post: RE: Methods of running a script on Linux distro

I would like to point out that you should use sudo judiciously, i.e. only if you need to. In this case it was not required and chmod as normal user would have been sufficient.

Normally you would chmod +x script.py to make it executable without having to specify python on the command line explicitly.

Use plt.draw() instead of plt.show(). Each call to plt.draw() will replot the image, for example after adding more data to it.

It looks like pandas indeed does use classes for this as seen here. It also looks like a complex project!
