title: Python scope of numerical type
body: <p>I use python3.x,I want to know the scope of numerical type.</p>
  
  <p>For example, the float, the maximum and the minimum.</p>
  
  <p>I know the scope of java's float and int, but in python I can't find it now.</p>
  
  <p>For example,java float from 10^-38 to 10^38,so python's float?</p>
