I am doing data transfer from an instrument over RS232 serial dialogue using Python. The data is coming in ASCII format. For example this is what i get in ASCII from the instrument using Python:
'\x02S20390908127F010102F3004000900300000000000000000000000000000300A500000000000202020202020206070505050505050000000707070707070707020700000000000000000000000000000000000000008000800089237A0715047E000000000000000000000000000000000000000000000000000000000000000000000000005350374646303030\x1732'
The same data transfer using Hyperterminal (Docklight) gave me this and the following is the hex representation i got in hyperterminal:
02 53 31 38 33 38 30 39 30 38 31 32 37 46 30 31 30 31 30 32 46 33 30 30 34 30 30 30 39 30 30 33 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 33 30 30 41 35 30 30 30 30 30 30 30 30 30 30 30 32 30 32 30 32 30 32 30 32 30 32 30 32 30 36 30 37 30 35 30 35 30 35 30 35 30 35 30 35 30 30 30 30 30 30 30 37 30 37 30 37 30 37 30 37 30 37 30 37 30 37 30 32 30 37 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 38 30 30 30 38 30 30 30 38 39 32 33 37 41 30 37 31 35 30 34 37 45 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 35 33 35 30 33 37 34 36 34 36 33 30 33 30 33 30 17 33 38
My question is that how do I, using Python, get the same hex representation from the ascii data I got. I am very much of a noob when it comes to this kind of stuff. Thank you in advance.
Explanation: convert each character into byte using
ord
then format as two digit hex number and feed it into a list. Then join the list using space as a separator.
