tf.name_scope(args, *kwds)

Returns a context manager for use when defining a Python op.

https://tensorflow.google.cn/versions/r1.0/api_docs/python/tf/name_scope

tf.variable_scope(args, *kwds)

Returns a context manager for defining ops that creates variables (layers).

This context manager validates that the (optional) values are from the same graph, ensures that graph is the default graph, and pushes a name scope and a variable scope.
