It's not that it has or has not, due to its highness of level, but more a needs or needs not. In Python, iterating over an array is done with a for loop and the array's own iterator (or enumerate() if you need the indices), but C doesn't have iterators, so it needs a convenient notation for incrementing through the array. > BTW, array operations optimize to the same thing as pointer arithmetic in > most C compilers, but the latter tends to be less clear. I'm not fully convinced; there are many times when incrementing pointers allows for much cleaner code. However, we are talking about the readability of C among Python programmers. Personally, I find pointer-dereference-and-post-increment to be perfectly readable, but it's a construct that I use practically on a daily basis. To someone who's not familiar with Python, list comps could suffer from the same issues - what does THIS do? oh. Chris Angelico
