In Python 3.5+, encode the string to bytes and use the hex() method, returning a string.
s = "hello".encode("utf-8").hex()
s
# '68656c6c6f'
Optionally convert the string back to bytes:
b = bytes(s, "utf-8")
b
# b'68656c6c6f'

In python 3x Use binascii instead of hex:
>>> import binascii
>>> binascii.hexlify(b'< character / string>')

To print:
for c in test:
print(hex(ord(c)))
To convert:
output = ''.join(hex(ord(c)) for c in test)
or without the '0x' in output:
output = ''.join(hex(ord(c))[2:] for c in test)

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.

September 5, 2016 - When you convert from bytes to str, you are decoding; when you convert from str to bytes, you are encoding. That is, the byte sequence is the "code" that represents the string's abstracted contents (code points, which in turn represent characters) In 3.x, we can decode by using the special-cased version of str that takes extra arguments:

And then convert those strings to bytes using the encode () method. And then, we print those bytes, which we can see in the output line number 1. Line 10 to 13: We call the hex () method using the dot operator, and now the bytes are converted to the hexadecimal string value we required.

You are looking for the chr function.
You seem to be mixing decimal representations of integers and hex representations of integers, so it's not entirely clear what you need. Based on the description you gave, I think one of these snippets shows what you want.
>>> chr(0x65) == '\x65'
True
>>> hex(65)
'0x41'
>>> chr(65) == '\x41'
True
Note that this is quite different from a string containing an integer as hex. If that is what you want, use the hex builtin.

This will convert an integer to a 2 digit hex string with the 0x prefix:

r/learnpython on Reddit: Converting string to ASCII HEX Python 3
November 22, 2020 -
Hi all,
I've been struggling with this for an hour or so, I'm trying to take a string such as
'Hell' to '\x48\x65\x6c\x6c'
For what I'm doing, I require the \x before the ascii hex
This is a dated solution from StackOverflow, that doesn't work on Python3
>>> mystring = "Hello World"
>>> print ''.join(r'\x{02:x}'.format(ord(c)) for c in mystring)
\x48\x65\x6c\x6c\x6f\x20\x57\x6f\x72\x6c\x64 My new solution goes like this:
mystring = b'hello world'
#convert to hex
mystring = hexlify(mystring)
mystring = mystring.decode('ascii')
# hex, like this 68656c6c6f20776f726c64
#add in the \x in the right spots
mystring = '\\x'.join(mystring[i:i + 2] for i in range(-2, len(mystring), 2))
#looks like this at this point \x68\x65\x6c\x6c\x6f\x20\x77\x6f\x72\x6c\x64
#I need it back into the "b" format, so I encode it
mystring=mystring.encode(ascii)
# This breaks everything, now it becomes:
# b'\\x68\\x65\\x6c\\x6c\\x6f\\x20\\x77\\x6f\\x72\\x6c\\x64'
# I specifically can't use the double backslashes.Any ideas how to fix this or am I going about this all wrong? Thanks

I think the link where you got the code (presumably https://stackoverflow.com/questions/34975528/how-can-i-produce-a-hex-escaped-string-in-python-that-i-can-use-in-c ) just has a buggy example. >>> mystring = "Hello World" >>> print(''.join(r'\x{:02x}'.format(ord(c)) for c in mystring)) \x48\x65\x6c\x6c\x6f\x20\x57\x6f\x72\x6c\x64 I changed it to the print() function, and moved the ':' inside the string replacement field to the correct location. Edit: and here's the round-trip: >>> mystring = "Hello World" >>> a = ''.join(r'\x{:02x}'.format(ord(c)) for c in mystring) >>> a '\\x48\\x65\\x6c\\x6c\\x6f\\x20\\x57\\x6f\\x72\\x6c\\x64' >>> import ast >>> ast.literal_eval('"' + a + '"') 'Hello World'

May I ask why you want that format? You've already got some answers on how to go about it, but there might be a way to avoid needing to do this in the first place.

Python String to Hex [Explained with Code Examples] - JSON Viewer
July 5, 2023 - From the example code defines a Python string variable string with the value “Goom”. We then use the encode() method on this string variable to convert it to bytes and store the result in a variable called bytes and that can be used for various purposes like data transmission or storage. The hex() method cannot create a hexadecimal representation of a string without first converting it to bytes.
