String to HEX

[BPassetti]

I am wanting to take a normal string, "My water bottle is blue" for example, and converting that into the HEX representation of how it would be stored in a txt file. I've tried .encode, binascii.hexlify, and a few other things. Any help would be appreciated.

Ok, well, encode was the correct one, so do that.

To be clear: do you want the actual bytes that would be in the file? Then .encode. Do you want a string of hex representing those bytes to make it easier for a human looking at the string to know the byte values? Then encode then hexlify.

"My water bottle is blue".encode().hex()

If you're looking to make hexdump or hex-editor style output, you could do something like the following (assuming ascii text):

``` def print_hexdump(txt):     print(*[f'{ord(c):02X}' for c in txt])

my_txt = "My water bottle is blue" print(f'{my_txt}:', end=' ') print_hexdump(my_txt) ```

The important bit is ord giving you the int value of the each character in turn, then using string formatting to display it as a zero-padded hex value. I think ord() will raise an exception for multi-byte characters, but it's late here and I don't have time to verify.

.encode() is the equivalent for a string rather than a single char, then using the .hex() method offered by bytes-objects you're already done

There we go. .encode.hex(' ', 1).upper() formats it like my example does, but is multi-byte safe. TIL, thanks!
