Double values can be formatted compactly with 15 digits of precision (which is the most that IEEE 754 "double" can guarantee) using double_format='.15g'. To ensure that converting to text and back to a proto will result in an identical value, double_format='.17g' should be used. Args: message: The protocol buffers message. as_utf8: Return unescaped Unicode for non-ASCII characters. In Python 3 actual Unicode characters may appear as is in strings. In Python 2 the return value will be valid UTF-8 rather than only ASCII. as_one_line: Don't introduce newlines between fields. use_short_repeated_primitives: Use short repeated format for primitives. pointy_brackets: If True, use angle brackets instead of curly braces for nesting. use_index_order: If True, fields of a proto message will be printed using the order defined in source code instead of the field number, extensions will be printed at the end of the message and their relative order is determined by the extension number. By default, use the field number order. float_format: If set, use this to specify float field formatting (per the "Format Specification Mini-Language"); otherwise, 8 valid digits is used (default '.8g'). Also affect double field if double_format is not set but float_format is set. double_format: If set, use this to specify double field formatting (per the "Format Specification Mini-Language"); if it is not set but float_format is set, use float_format. Otherwise, use str() use_field_number: If True, print field numbers instead of names. descriptor_pool: A DescriptorPool used to resolve Any types. indent: The initial indent level, in terms of spaces, for pretty print. message_formatter: A function(message, indent, as_one_line): unicode|None to custom format selected sub-messages (usually based on message type). Use to pretty print parts of the protobuf for easier diffing. print_unknown_fields: If True, unknown fields will be printed.
