Title Body

Before jumping into python, I had started with some Objective-C / Cocoa books. As I recall, most functions required keyword arguments to be explicitly stated. Until recently I forgot all about this, and just used positional arguments in Python. But lately, I've ran into a few bugs which resulted from improper positions - sneaky little things they were. Got me thinking - generally speaking, unless there is a circumstance that specifically requires non-keyword arguments - is there any good reason NOT to use keyword arguments? Is it considered bad style to always use them, even for simple functions? I feel like as most of my 50-line programs have been scaling to 500 or more lines regularly, if I just get accustomed to always using keyword arguments, the code will be more easily readable and maintainable as it grows. Any reason this might not be so? UPDATE: The general impression I am getting is that its a style preference, with many good arguments that they should generally not be used for very simple arguments, but are otherwise consistent with good style. Before accepting I just want to clarify though - is there any specific non-style problems that arise from this method - for instance, significant performance hits?
