How to plot hour:min time in ISO 8601 time format?
I am trying to plot temperature data points according to their time recording. Note: as you have mentioned t is represented without hour, the reason is that temp been collected in hour:second. t is a string representing the date and time in ISO 8601 format (ref: datetime.datetime.isoformat()) and temp is a fl…
Numpy rounding issue
Can someone explain to me why is numpy round acting strange with this exact number rounding: It’s obvious that the first number is not rounded well, any ideas? EDIT: Since I’m focused here on the precision, not so much on the performance, I’ve used python round function to solve this problem…

I have a 2d gaussian whose center has been destroyed by pixel saturation. I need the center to be filled in because a poorly filled in center will confuse a neural network I’m trying to train. See below: The scattered nan values I can handle fairly easily, but the large cluster in the gaussian’s c…
convert multiple units to KG in pandas
let’s say i have this code(which is obviously wrong) I want to apply such condition to each value in a column(weights) based on another column(weight unit). Is there an efficient way to do it. Preferably allowing a func pass so easy to modify Answer Don’t use a function, this will be slow. numpy.v…
Reordering a list based on another list in Python
I have two lists Ii0 and Iv0 containing numpy arrays. I am using argsort() to reorder elements in Ii0 to generate a new list Ii01. I want to use the same order to reorder elements in Iv0 to generate a new list Iv01. I present the current and expected output. The current output is The expected output is Answer…
