In my Java code I have the following snippet :
String secret = "secret";
byte[] thebytes = secret.getBytes();
I would like to have exactly the same result in python. How can I do that ?
secret = 'secret'
thebytes = ??? ??? ???
Thanks.
EDIT:
In addition, it will be interesting to have the solution for Python 2.x and 3.x
This is not as simple as it might first seem, because Python has historically conflated byte arrays and strings. The short answer, in Python 3, is
secret = "secret"
secret.encode()
But you should read up on how Python deals with unicode, strings and bytes.
str in Python 2.x is a string of bytes. If you want their byte value as an integer then map(ord, secret), as @Linus said.In python-2.7 there's bytearray():
>>> s = 'secret'
>>> b = bytearray(s)
>>> for i in b:
... print i
115
101
99
114
101
116
If this is what you're looking for.
I'm not sure about exactly the same, since Python doesn't have byte, but this might do the trick:
bytes = [ord(c) for c in "secret"] # => [115, 101, 99, 114, 101, 116]
Or using map, as katrielalex suggested, just because it's pretty:
bytes = map(ord, "secret") # => [115, 101, 99, 114, 101, 116]
map(ord, "secret") not showing as you display in above sample array. It shows as <map object at 0x0000026298F0F940>. Please guide me how to get byte array
list(map(foo, iterable))
secret.getBytes()?stris bytes. Thestrtype represents bytes. It contains bytes. How would you like to have the bytes, what do you want to do with them?
