How to get top-level protobuf enum value name by number in python?

For example, I have proto-file File.proto: enum Test { ONE = 1; TWO = 2; } I generate file File_pb2.py with protoc from File.proto. I want in a python-code get string "ONE" (that corresponds to the name of File_pb2.ONE) by value 1 (that corresponds to the value of File_pb2.ONE) from generated file File_pb2.py without defining my own dictionaries. How can I do that?
Assuming the generated python is located in File_pb2.py code Try this: file_pb2._TEST.values_by_number[1].name In your case, this should give 'ONE' The reverse is : file_pb2._TEST.values_by_name['ONE'].number will give 1. EDIT: As correctly pointed by @dyoo in the comments, a new method was later introduced in protobuf library: file_pb2.Test.Name(1) file_pb2.Test.Value('One') EDIT: This has changed again in proto3. Now the Name() and Value() methods belong to the EnumTypeWrapper class so they can be accessed like: file_pb2.Name(1) file_pb2.Value('One')
