Hex to a String Python

Question

I would like to convert

the hex value

a = 0x32

to a string d = 32

Bascially I have a numpy array

msg = np.array[2, 50]

I need to convert both values to hex --- [0x02 , 0x32] then print the hex values as strings on GUI as 2, 32

Here is a duplicate http://stackoverflow.com/questions/9448029/print-an-integer-array-as-hexadecimal-numbers — Mazdak, Aug 25 '16 at 14:36

hex() will give you hex string. Then discard first 2 characters

>>> hex(a)
'0x32'
>>> hex(a)[2:]
'32'
>>>

Looking at the link to duplicate, it seems numpy is giving you the L at the end since you are running 64bit linux. so do this:

hex(a)[2:-1]

I have 0x32L not 0x32, Could you also tell me why I have 0x32L ? – Jesh Kundem Aug 25 '16 at 14:34
do you always have L at the end? what python version? – joel goldstick Aug 25 '16 at 14:35
PYthon 2.7 Version – Jesh Kundem Aug 25 '16 at 14:36
Try this : msg = np.array([2 ,50]) d = hex(msg[1]) print d – Jesh Kundem Aug 25 '16 at 14:47
