Python 3.1.1 string to hex

Question

I am trying to use str.encode() but I get

>>> \"hello\".encode(hex)
Traceback (most recent call last):
  File \"\", line 1         


        

Answer 1

Use hexlify - http://epydoc.sourceforge.net/stdlib/binascii-module.html

Answer 2

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'

Answer 3

binascii methodes are easier by the way

>>> import binascii
>>> x=b'test'
>>> x=binascii.hexlify(x)
>>> x
b'74657374'
>>> y=str(x,'ascii')
>>> y
'74657374'
>>> x=binascii.unhexlify(x)
>>> x
b'test'
>>> y=str(x,'ascii')
>>> y
'test'

Hope it helps. :)
