Question

I need convert this array

data = [
#SHO
0x56, 0x0d, 
#CMD
0x1, 0x00, 0x00, 0x00, 
#ARG
0x1, 0x0,
#SIZE
0x02, 0x00, 0x00, 0x00, 
#OPAQUE
0x01, 0x02,
#RESERVED
0x00, 0x00
]

and produce a string

# converted data into s
print s

Answer 1

In [16]: ''.join(str(i) for i in data)
Out[16]: '861310001020001200'

or (as perhaps as per @thg435’s suggestion) using chr() in place of str():

In [25]: ''.join(chr(i) for i in data)
Out[25]: 'V\r\x01\x00\x00\x00\x01\x00\x02\x00\x00\x00\x01\x02\x00\x00'

Is this what you are looking for? If not, can you provide the desired output?
