convert bytes-string ("b'sample'") to bytes (b'sample')

via ast.literal_eval (partial ok)

ref: How to convert Python bytes string representation to bytes? - Stack Overflow

cons: it only supports ascii transfer.

sample:

import ast

b1 = b'{"name":"mark"}'
s1 = """b'{"name":"mark"}'"""

b2 = b'{"name":"\xe5\xbb\x96*"}'
s2 = """b'{"name":"\xe5\xbb\x96*"}'"""

# ok
assert ast.literal_eval(s1) == b1

# fail, since `ast.literal_eval` doesn't support utf-8
assert ast.literal_eval(s2) == b2
