The hex() and oct() functions let you convert this decimal integer into strings with the corresponding hexadecimal and octal representations, respectively. Note that you must format such strings slightly differently in your string literal to turn them into escape sequences: Python >>> "...
There are two formats for transferring data from a server to a vertica-python client: text and binary. For example, a FLOAT type data is represented as a 8-byte IEEE-754 floating point number (fixed-width) in binary format, and a human-readable string (variable-width) in text format. ...
