declaimed the following:
I wanted to learn about conversion string to Ascii.
So I learn about binascii.b2a but because the output wasn't what I
wanted got deeper and found out about ord(c) and actually that's what
I'expected.
So what's that binascii and why I cant convert ascii that I got from ord
to string by using char, instead I'm getting some strings in weird
coding.
import binascii
Ttext = b'This is a string'
text2 = 'This is a string'
Item: this is a Unicode string. Python Unicode strings are only 1-byte
per character IF all characters are in the 7-bit ASCII range. If you have
any extended characters (which would, say, be one byte in ISO-Latin-1) they
could turn the entire Unicode string into 2-byte per character (and really
expanded sets could be 3 or 4 bytes per character).
[snip]
Are you confusing the internal representation in CPython 3.3+ with UTF-8?
In CPython 3.3+, Unicode strings are stored as 1 byte per codepoint if
all of the codepoints are U+0000..U+00FF, else as 2 bytes per codepoint
if all are U+010000..U+10FFFF, else as 4 bytes per codepoint.
But that's an implementation detail.
