Python pltplot graph, show empty graph

I don’t seem to find problem why graph is not showing any lines, its just blank im new in python
"Trying to plot graph maximum height and range with angle"

import matplotlib.pyplot as plt
import numpy as np
def projectile(Vo,Angle):
Acc=9.8
Mheight=(Vo**2)*np.sin(np.radians(Angle**2))/Acc**2
Range=(Vo**2)*(np.sin(np.radians(Angle)))/Acc
plt.plot(int(Mheight),int(Angle)) // This is the line
plt.show()  // only showing blank graph
return ("Maximum Height: ",Mheight,"Maximum Range: ",Range)
#Main Function  
Vo=int(input("Enter Velocity: "))
Angle=int(input("Enter Angle: "))
print(projectile(Vo,Angle))

>Solution :

You should give plt.plot() a tuple object.

thus, like:

    plt.plot((int(Mheight),int(Angle)))
    plt.show() 

by the way, remember the typesetting of your code.
