| + | Users of curly bracket programming languages, such as C or Java, sometimes expect or wish Python to follow a block-delimiter convention. Brace-delimited block syntax has been repeatedly requested, and consistently rejected by core developers. The Python interpreter contains an easter egg that summarizes its developers' | ||

| + | Beautiful is better than ugly. | ||
| + | Explicit is better than implicit. | ||
| + | Simple is better than complex. | ||
| + | Complex is better than complicated. | ||
| + | Flat is better than nested. | ||

| + | Readability counts. | ||
| + | Special cases aren't special enough to break the rules. | ||
| + | Although practicality beats purity. | ||
| + | Errors should never pass silently. | ||
| + | Unless explicitly silenced. | ||

| + | Although that way may not be obvious at first unless you're Dutch. | ||
| + | Now is better than never. | ||
| + | Although never is often better than *right* now. | ||
| + | If the implementation is hard to explain, it's a bad idea. | ||
| + | If the implementation is easy to explain, it may be a good idea. | ||
| + | Namespaces are one honking great idea -- let's do more of those! | ||
