I can't figure out how to put the per mille symbol into my plt.ylabel. anyone know how?
import numpy as np
import matplotlib.pyplot as plt
plt.plot(x,y)
ax = plt.gca()
ax.invert_yaxis()
plt.title("LR04 Benthic $\delta^{18}$O")
plt.xlabel("Years (ka)")
plt.ylabel("Benthic $\delta^{18}O (TRYING TO PUT PERMIL SYMBOL HERE)$")
plt.show()
