Scalar Value Types

.proto Type	Notes	Python Type
double		float
float		float
int32	Uses variable-length encoding. Inefficient for encoding negative numbers – if your field is likely to have negative values, use sint32 instead.	int
int64	Uses variable-length encoding. Inefficient for encoding negative numbers – if your field is likely to have negative values, use sint64 instead.	int/long
uint32	Uses variable-length encoding.	int/long
uint64	Uses variable-length encoding.	int/long
sint32	Uses variable-length encoding. Signed int value. These more efficiently encode negative numbers than regular int32s.	int
sint64	Uses variable-length encoding. Signed int value. These more efficiently encode negative numbers than regular int64s.	int/long
fixed32	Always four bytes. More efficient than uint32 if values are often greater than 2^28.	int
fixed64	Always eight bytes. More efficient than uint64 if values are often greater than 2^56.	int/long
sfixed32	Always four bytes.	int
sfixed64	Always eight bytes.	int/long
bool		boolean
string	A string must always contain UTF-8 encoded or 7-bit ASCII text.	str/unicode
bytes	May contain any arbitrary sequence of bytes.	str
