+
+Syntax error while calling a method on an integer value
+-------------------------------------------------------
+
+You get a syntax error when trying to call a method on 
+``int`` value as follows.
+
+    >>> 5.__class__
+    File "<stdin>", line 1
+    5.__class__
+              ^
+    SyntaxError: invalid syntax
+
+This is because  the Python parser considers that a period written after 
+a number literal is a decimal point, so to turn that period into an attribute 
+access you have to add parentheses around the literal. In the above case, 
+the tokenizer sees the '.' as making the token a float, and ``5.__class__`` 
+is not a valid float token.
+
+The right way to call a method on an integer is as follows:
+
+    >>> (5).__class__
+    <type 'int'>

 Each value is an object, and therefore has a *class* (also called its *type*).
 It is stored as ``object.__class__``.
