Close pre-existing figures in matplotlib when running from eclipse

by

You can close a figure by calling matplotlib.pyplot.close, for example: from numpy import * import matplotlib.pyplot as plt from scipy import * t = linspace(0, 0.1,1000) w = 60*2*pi fig = plt.figure() plt.plot(t,cos(w*t)) plt.plot(t,cos(w*t-2*pi/3)) plt.plot(t,cos(w*t-4*pi/3)) plt.show() plt.close(fig) You can also close all open figures by calling matplotlib.pyplot.close(“all”)

So use raw string when you mean literal \ and d: re.compile(r”\d{3}”) or escape backslash explicitly: re.compile(“\\d{3}”)
