I'm making this exercise: (Python 3.3)Write a function translate() that will translate a text into "rövarspråket" (Swedish for "robber's language"). That is, double every consonant and place an occurrence of "o" in between. For example, translate("this is fun") should return the string "tothohisos isos fofunon". So I tried to solved it, but I couldn't, so I found many answers, but I selected this: def translate(s): consonants = 'bcdfghjklmnpqrstvwxz' return ''.join(l + 'o' + l if l in consonants else l for l in s) print(translate('hello code solver')) OUTPUT: 'hohelollolo cocodode sosololvoveror' ______________________________________________________________ So I want to question: How is the if 'h' in consonants else 'h' for 'h' in s part evaluated? (step by step please :P ) ''.join('h' + 'o' + 'h' if 'h' in consonants else 'h' for 'h' in s) Thank you guys
This doesn't make much sence because you substituted a varible for a character literal, so I'll go with the original. l + 'o' + l if l in consonants else l for l in s Evaluate this expression: l + 'o' + l if l in consonants else l for each l in s (so for each letter that in s). l + 'o' + l if l in consonants else l if l is part of the consonants produce l + 'o' + l otherwise just produce l. Hope this helps. -- Antoon Pardon -- http://mail.python.org/mailman/listinfo/python-list
