Extracted text: Exercise 6 Derive a Python function named code that take a character chain s and returns another coded chain. The code is calculated by taking each pair of consecutive letters and changing the order in the pair (spaces, ponctuation, etc. are traited like letters). Test your function with a main program or in the interpretor. For example: >>> code('secret message') 'esrctem seaseg' >>> code('Message') 'eMssgae'
