python equivalent of ruby's ASCII-8BIT encoding scheme

Question

I need to encoding something in ASCII-8BIT because it's part of the specification of the program.

The demo code is written in ruby and they have used Encoding::BINARY which is equivalent to ASCII-8BIT

Below is the encoding aliases of ruby

Encoding.aliases
#=> {"BINARY"=>"ASCII-8BIT", "ASCII"=>"US-ASCII", "ANSI_X3.4-1986"=>"US-ASCII",
      "SJIS"=>"Shift_JIS", "eucJP"=>"EUC-JP", "CP932"=>"Windows-31J"}

I need something in python for the ASCII-8BIT. The default ASCII has 0-255 i.e total 8 bits, but im not sure if thats what i need to do.

will "str".encode("ASCII") suffice ?

There is no such thing as an ASCII-8bit encoding; it probably is Latin-1. — Martijn Pieters, Nov 13 '16 at 22:03

The Python equivalent is Latin-1; all Unicode codepoints from 0x00 through to 0xFF are mapped one-on-one to bytes with the same value.

Note that this would encode Unicode to a bytestring. In Python 2.7, str is already a bytestring and doesn't need encoding.

@Anup: hmm, any example input? – Martijn Pieters Nov 13 '16 at 22:07
Haha nice one, so if i have "SGVsbG8sIFdvcmxkIQ", encoding it to Latin-1 will help me identify and to process in a different way. So if i have a normal string, and a Latin-1 encoded string, i need to perform something else. Thats my main goal – mega-crazy Nov 13 '16 at 22:09
That's just standard ASCII data though. – Martijn Pieters Nov 13 '16 at 22:11
@Anup: again, ASCII would suffice for that. – Martijn Pieters Nov 13 '16 at 22:20
