# A function to calculate area of triangle (1/2 base times height) def areaOfTriangle( base, height ): area = 0.5 * base * height return area ##### Main execution area of your program. # Ask user for base and height, store in variables base = raw_input("Enter triangle base length: ") height = raw_input("Enter triangle height: ") # The numbers entered are still just keyboard characters # We need to cast them to floats (numbers with decimal points) base = float( base ) height = float( height ) # Pass our base and height variables to the function print 'Area of triangle is', areaOfTriangle( base, height ) # We can also store the return value in a variable # and use it however we want. area = areaOfTriangle( base, height ) print 'The area of the triangle is', area
