The standard way to add vertical lines that will cover your entire plot window without you having to specify their actual height is plt.axvline import matplotlib.pyplot as plt plt.axvline(x=0.22058956) plt.axvline(x=0.33088437) plt.axvline(x=2.20589566) OR xcoords = [0.22058956, 0.33088437, 2.20589566] for xc in xcoords: plt.axvline(x=xc) You can use many of the keywords available for other plot commands (e.g. … Read more

If you are interested in getting the id of a newly inserted row, there … Read more
This will give you a sorted version of the array. sorted(timestamps, reverse=True) If you want to sort in-place: timestamps.sort(reverse=True) Check the docs at Sorting HOW TO
Patrick Smacchia blogged about this last month, with the following conclusions: for loops on List are a bit more than 2 times cheaper than foreach loops on List. Looping on array is around 2 times cheaper than looping on List. As a consequence, looping on array using for is 5 times cheaper than looping on … Read more
np.r_[ … ] and np.c_[ … ] are useful alternatives to vstack and hstack, with square brackets [] instead of round (). A couple of examples: : import numpy as np : N = 3 : A = np.eye(N) : np.c_[ A, np.ones(N) ] # add a column array([[ 1., 0., 0., 1.], [ 0., … Read more
