How to plot all possible (x,y) points with two arrays

Question

X = np.array([1,2,3,4,5])    
Y = np.array([1,2,3,4,5])

I need to plot with scatter these point ==> (1,1),(1,2),(1,3),...,(5,3),(5,4),(5,5)

If we try:

X = np.array([1,2,3,4,5])   
Y = np.array([1,2,3,4,5])      
fig = plt.figure()
ax = fig.add_subplot(111)
ax.scatter(X,Y)
plt.show()

result is only these point ==> (1,1),(2,2),(3,3),(4,4),(5,5)

Specifically, I am trying to mark all possible (x, y) binaries that can be created from the given x and y binaries

A,B = np.meshgrid(X,Y)                                                                                      
plt.scatter(A,B)

thx for answer , can we print all these (x,y) variables ? – Enes Jun 04 '20 at 11:59
Sure @EnesA, just do: `all_pnts = np.stack((A,B), axis=2).reshape(-1,2) ` – imochoa Jun 04 '20 at 13:01
thx for help :D – Enes Jun 04 '20 at 13:41

all_pts_x, all_pts_y = np.meshgrid(X, Y)
ax.scatter(all_pts_x, all_pts_y)
