Hi Christopher,
I don't know if my suggestion is the best way, but at least it may be
useful ...
regards Matthias
example code:
import matplotlib
import matplotlib.pyplot as plt
for i in range(5)+[14]:
plt.figure(i) # generating some figures
# get the figure numbers of all existing figures
fig_numbers = [x.num
for x in matplotlib._pylab_helpers.Gcf.get_all_fig_managers()]
if 14 in fig_numbers:
print "figure 14 exists"
if plt.figure(14).number in fig_numbers:
print "figure 14 exists"
