Andrés Delfino added the comment: And what should symbols show in pydoc? Should symbols show: 1. All legal combinations with ("'", '"') (48 possible combinations) 2. Only b/f/r/u with ("'", '"') (IMHO, this is the most reasonable option) 3. Only b/f/r/u with ' or " Depending on that, we can

Serhiy Storchaka added the comment: I don't think we need to support prefixes without quotes or with triple qoutes. 'ur' is not valid prefix. Using simplified code from tokenize: _strprefixes = [''.join(u) + q for t in ('b', 'r', 'u', 'f', 'br', 'rb', 'fr', 'rf'

Andrés Delfino added the comment: To get the 144 combinations I used the logic in tokenize.py: import re def _combinations(*l): return set( x + y for x in l for y in l + ("",) if x.casefold() != y.casefold() ) _strprefixes = ( _combinations('r', 'R', 'f', 'F') | _combinati

Serhiy Storchaka added the comment: Interesting, I didn't know that pydoc supports this. Specifying all possible prefixes is cumbersome and errorprone. The number of combinations grows exponentially with adding new letters. I suggest either to specify only lower-case variants and generate all

New submission from Andrés Delfino : Right now, for string/byte literals help() shows, for example: No Python documentation found for 'r'. Use help() to get the interactive help utility. Use help(str) for help on the str class. PR fixes the quotation mark removal and updates the list with f and
