# example python program x = 0. xmax = 2. xincr = .1 while x < xmax: # Here is a block of code designated by : y = x * x print(x, y) x += xincr # the built-in type() function returns a string of the type of a variable print type(x) print type(xmax) print type(xincr) # note: no declaration of scalar variables # python does dynamic typing
