#----------------------------------------
print()
print( "Welcome to the Area calculation program" )
print( "---------------------------------------" )
print()
# Print out the menu:
print( "Please select a shape:" )
print( "1 Rectangle" )
print( "2 Circle" )
print()
# The input function both prompts the user
# for input and fetches it...
shape = int( input( "> " ) )
# Calculate the area...
if shape == 1:
height = int( input("Please enter the height: ") )
width = int( input("Please enter the width: ") )
area = height*width
print( "The area is", area )
else:
radius = int( input("Please enter the radius: ") )
area = 3.14*(radius**2)
print( "The area is", area )
input( '\n\nPress Enter to exit...' )
