matplotlib has an event handling API you can use to hook in to actions like the ones you’re referring to. The Event Handling page gives an overview of the events API, and there’s a (very) brief mention of the x- and y- limits events on the Axes page. The Axes instance supports callbacks through a … Read more
itertools functions return iterators, objects that produce results lazily, on demand. You could either loop over the object with a for loop, or turn the result into a list by calling list() on it: from itertools import chain, combinations def powerset(iterable): “powerset([1,2,3]) –> () (1,) (2,) (3,) (1,2) (1,3) (2,3) (1,2,3)” s = list(iterable) return … Read more
There a couple of different ways to go about this. You can monkey-patch ax.format_coord, similar to this official example. I’m going to use a slightly more “pythonic” approach here that doesn’t rely on global variables. (Note that I’m assuming no extent kwarg was specified, similar to the matplotlib example. To be fully general, you need … Read more
You need inplace=True df[1].fillna(0, inplace=True)
set useOffset to False: ax = plt.gca() ax.ticklabel_format(useOffset=False)
Here is a FuncAnimation example which I modified to pause on mouse clicks. Since the animation is driven by a generator function, simData, when the global variable pause is True, yielding the same data makes the animation appear paused. The value of paused is toggled by setting up an event callback: def onClick(event): global pause … Read more
str.count() counts non-overlapping occurrences of the substring: Return the number of non-overlapping occurrences of substring sub. There is exactly one such place where the substring ” occurs in the string ”: right at the start. So the count should return 1. Generally speaking, the empty string will match at all positions in a given string, … Read more
Option 1 You should start your Thread before calling uvicorn.run, as uvicorn.run is blocking the thread. import time import threading from fastapi import FastAPI import uvicorn app = FastAPI() class BackgroundTasks(threading.Thread): def run(self,*args,**kwargs): while True: print(‘Hello’) time.sleep(5) if __name__ == ‘__main__’: t = BackgroundTasks() t.start() uvicorn.run(app, host=”0.0.0.0″, port=8000) You could also start your thread using … Read more
I think you’ve almost got it. Is this what you want? from mpl_toolkits.mplot3d import Axes3D from mpl_toolkits.mplot3d.art3d import Poly3DCollection import matplotlib.pyplot as plt fig = plt.figure() ax = Axes3D(fig, auto_add_to_figure=False) fig.add_axes(ax) x = [0,1,1,0] y = [0,0,1,1] z = [0,1,0,1] verts = [list(zip(x,y,z))] ax.add_collection3d(Poly3DCollection(verts)) plt.show() You might also be interested in art3d.pathpatch_2d_to_3d.
