 // `Any` contains an arbitrary serialized protocol buffer message along with a
 // URL that describes the type of the serialized message.
 //
 // Protobuf library provides support to pack/unpack Any values in the form
 // of utility functions or additional generated methods of the Any type.
 //
 // Example 1: Pack and unpack a message in C++.
 //
 //     Foo foo = ...;
 //     Any any;
 //     any.PackFrom(foo);
 //     ...
 //     if (any.UnpackTo(&foo)) {
 //       ...
 //     }
 //
 // Example 2: Pack and unpack a message in Java.
 //
 //     Foo foo = ...;
 //     Any any = Any.pack(foo);
 //     ...
 //     if (any.is(Foo.class)) {
 //       foo = any.unpack(Foo.class);
 //     }
 //
-//  Example 3: Pack and unpack a message in Python.
-//
-//     foo = Foo(...)
-//     any = Any()
-//     any.Pack(foo)
-//     ...
-//     if any.Is(Foo.DESCRIPTOR):
-//       any.Unpack(foo)
-//       ...
-//
 // The pack methods provided by protobuf library will by default use
 // 'type.googleapis.com/full.type.name' as the type URL and the unpack
 // methods only use the fully qualified type name after the last '/'
 // in the type URL, for example "foo.bar.com/x/y.z" will yield type
 // name "y.z".
