I'm trying to find a way to output strings in the raw-string format, e.g.
print_as_raw_string(r"\.") should output r"\." instead of "\\." ...
In any case, this is just a variation of what repr() does.
repr(r'\.')
"'\\\\.'"
What the OP seems to want is something like:... a barely tested version:
def raw_repr(s):
"""Return the repr of string s as a raw-string."""
r = repr(s)
if '\\\\' in r:
r = "r" + r.replace('\\\\', '\\')
assert not r.endswith('\\')
return r
...
The big issue I see is that lots of values cannot be represented
as raw strings. Your code checks for a final '\', but many "control"
characters and the quote marks are also at issue.
raw_repr('["\']a\x13\xfebc\\de') should contain several nasty cases.
