Question

I have a hex string like:

data = "437c2123"

I want to convert this string to a sequence of characters according to the ASCII table.
The result should be like:

data_con = "C|!#"

Can anyone tell me how to do this?

Answer 1

In [17]: data = "437c2123"

In [18]: ''.join(chr(int(data[i:i+2], 16)) for i in range(0, len(data), 2))
Out[18]: 'C|!#'

Here:

• for i in range(0, len(data), 2) iterates over every second position in data: 0, 2, 4 etc.
• data[i:i+2] looks at every pair of hex digits '43', '7c', etc.
• chr(int(..., 16)) converts the pair of hex digits into the corresponding character.
• ''.join(...) merges the characters into a single string.
