Convert string to ASCII value python

Question

How would you convert a string to ASCII values?

For example, \"hi\" would return 104105.

I can individually do ord(\'h\') and ord(\'i\'), but it\'s going to

Answer 1

def stringToNumbers(ord(message)):
    return stringToNumbers
    stringToNumbers.append = (ord[0])
    stringToNumbers = ("morocco")

Answer 2

you can actually do it with numpy:

import numpy as np
a = np.fromstring('hi', dtype=np.uint8)
print(a)

Answer 3

If you want your result concatenated, as you show in your question, you could try something like:

>>> reduce(lambda x, y: str(x)+str(y), map(ord,"hello world"))
'10410110810811132119111114108100'

Answer 4

It is not at all obvious why one would want to concatenate the (decimal) "ascii values". What is certain is that concatenating them without leading zeroes (or some other padding or a delimiter) is useless -- nothing can be reliably recovered from such an output.

>>> tests = ["hi", "Hi", "HI", '\x0A\x29\x00\x05']
>>> ["".join("%d" % ord(c) for c in s) for s in tests]
['104105', '72105', '7273', '104105']

Note that the first 3 outputs are of different length. Note that the fourth result is the same as the first.

>>> ["".join("%03d" % ord(c) for c in s) for s in tests]
['104105', '072105', '072073', '010041000005']
>>> [" ".join("%d" % ord(c) for c in s) for s in tests]
['104 105', '72 105', '72 73', '10 41 0 5']
>>> ["".join("%02x" % ord(c) for c in s) for s in tests]
['6869', '4869', '4849', '0a290005']
>>>

Note no such problems.

Answer 5

If you are using python 3 or above,

>>> list(bytes(b'test'))
[116, 101, 115, 116]

Answer 6

Here is a pretty concise way to perform the concatenation:

>>> s = "hello world"
>>> ''.join(str(ord(c)) for c in s)
'10410110810811132119111114108100'

And a sort of fun alternative:

>>> '%d'*len(s) % tuple(map(ord, s))
'10410110810811132119111114108100'
