Correct. It's a trivial problem, but still a problem. > It's also a problem wrt. learning the language. This makes no sense. Why is it harder to learn print(x, y, z) than this? print x, y, z The first case is like the other functions you have to learn, like len(). In fact, many newbies to Python put unneeded parentheses around arguments to print simply because they assume it is a function. I would argue that the new print function is *simpler* to learn. It is more consistent with other built-ins, and has fewer magic idioms to learn. Instead of: print >>fileObj, x, y, z you use regular function syntax with a meaningful keyword: print(x, y, z, file=fileObj) If you want suppress the newline at the end of each print: print x, y, z, # note the final comma compared to: print(x, y, z, end='') If you want to change the space between elements, instead of: sys.stdout.write(str(x) + "*" + str(y) + "*" + str(z) + '\n') you use: print(x, y, z, sep='*') If you want to override the behaviour of print in a module, instead of having to edit the source code of the module (which might not even be available), all you need to do is monkey-patch it: import module module.print = myprint -- Steven -- http://mail.python.org/mailman/listinfo/python-list
