#python, printing alpha beta and theta symbols

# i want to be able to put an alpha beta and theta symbol in this graph using python
import numpy as np
import matplotlib.pyplot as plt

a = np.linspace(0,50,50)
b=[]
for i in a:
b.append(np.sin(i))

plt.plot(a,b)
####################################
####    problem is just below    #####
####################################
plt.xlabel('$\Theta$ (lol)')
plt.ylabel('$\Alpha$ (lol)')
plt.title('$\Beta$ (lol)')

plt.show()

Answer 1

Please let me know if you require any further assistance.

You have the right idea and we can put almost any mathematical symbols in python using this method->

                      r'$\theta$'                        # Use the 'r' tag and put any mathematical expression inside the '$' tags. use '\' backward slash before the name of any symbol.

So your final solution will be like this :

   

import matplotlib.pylab as plt
import numpy as np

a = np.linspace(0, 50, 50)
b=[]
for i in x:
    b.append(np.sin(i))
plt.plot(a,b)
plt.xlabel(r'$\theta$')
plt.ylabel(r'$\alpha$')
plt.title(r'$\beta$')
plt.show()

You will get your solution as shown in the picture below:
