Pairs is a list of patterns and responses. Each pattern is a regular expression matching the user's statement or question, e.g. r'I like (.*)'.

Material which is matched by parenthesized sections of the patterns (e.g. .*) is mapped to the numbered positions in the responses, e.g. %1. :type pairs: list of tuple :param pairs: The patterns and responses :type reflections: dict :param reflections: A mapping between first and second person expressions :rtype: None cVg|]&\}}tj|tj|f'S)recompile IGNORECASE).0xys J/var/www/html/ai-engine/env/lib/python3.11/site-packages/nltk/chat/util.py z!Chat.__init__..3s/MMMVa 1bm44a8MMMN)_pairs _reflections_compile_reflections_regex)selfpairs reflectionss r__init__z Chat.__init__#s9 NMuMMM '//11 rc t|jtd}tjddttj|tj S)NT)keyreversez\b({})\b|) sortedrlenrrformatjoinmapescaper)r sorted_refls rrzChat._compile_reflections7sZT.CFFF z   sxxBI{(C(CDD E Er}   rcdjfd|S)z Substitute words in the string, according to the specified reflections, e.g. "I'm" -> "you are" :type str: str :param str: The string to be mapped :rtype: str cj|j||S)N)rstringstartend)mors rz"Chat._substitute..Hs+t(288::3H)IJr)rsublower)rstrs` r _substitutezChat._substitute=s3{ J J J JCIIKK   rc.|d}|dkryt||dz|dz}|d||||z||dzdz}|d}|dky|S)N%r)findintr5group)rresponsematchposnums r _wildcardszChat._wildcardsKsmmC  QhhhsQwq0122C#""5;;s#3#34453799%&  --$$CQhhrc|jD]\}}||}|rdtj|}|||}|dddkr |dddz}|dddkr |dddz}|cSdS)z Generate a response to the user input. :type str: str :param str: The string to be mapped :rtype: str Nz?..z???)rr>randomchoicerA)rr4patternr=r>resps rrespondz Chat.respondWs"&   GXMM#&&E }X..tU339$$9s?D9$$9s?D    rquitcd}||kr||} td}n#t$rt|YnwxYw|r@|ddvr|dd}|ddvt||||kzdSdS)N>z!.)inputEOFErrorprintrJ)rrK user_inputs rconversez Chat.converseqs D  J ""3ZZ  " " "j!!!!!
