Hey guys new to python and programming in general.. Got this simple area calculator program but have a few questions on it. Once you do a calculation it quits.. I would like it to ask to continue to another calculation or quit but I don't know how to re-call the program. Are there ways like functions or blocks I could put the code in to call it to run whenever I want like run this part again for another calculation.

#-------------------
# PRINT OUT THE MENU
print "Please select a shape"
print "1 - Rectangle"
print "2 - Triangle"
print "3 - Circle"


#----------------
# GETS USER INPUT
shape = input(">> ")


#-----------------
# CALCULATING AREA
    # RECTANGLE
if shape == 1:
    height = input("Enter the Height: ")
    width = input("Enter the Width: ")
    area = height*width
    print "The area is ", area

    # TRIANGLE
elif shape == 2:
    base = input("Enter Base Value: ")
    height = input("Enter Height: ")
    area = .5*base*height
    print "The area is ", area

    # CIRCLE
else:
    radius = input("Enter the Radius: ")
    area = 3.14*(radius**2)
    print "The area is ", area

I need a way to block sections of code to run when I call for them but not sure how to do this.. Here is the source let me know if you have any questions about what I am asking... thanks.

Sorry for the double post but I already have another problem I forgot to address. Along with finding a way to call the program again.. As you can see now I added all the shapes in my elif statements and left the else statement in case someone chooses an option that is not valid. Now if they do choose something like say 6 which isn't an option.. how could I get it to show my print statement that is there but then also call the program to start again and ask to input your selection again. Thanks guys
