Got another one

You just need to check:

if x3 >= x1 and x3 <= x2:  #<---- means it is in range from left to right

and 

if  y3 >= y1 and y3 <= y2: #<---- means it is in range from up and down

If both those are True then it's in the rectangle.

Ah! Thank you. I'm assuming that I can use different input statements and assignment operators for the variables, and then use this statement? Also, you'll have to forgive me, but how will I structure it to show that it is True?
