In Python, is it considered better style to: explicitly d开发者_开发知识库efine useful functions in terms of more general, possibly internal use, functions; or,
In my Haskell program, I want to use pri开发者_JAVA百科ntf to format a list of tuples.I can map printf over a list to print out the values one at a time like this:
