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

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'
