Just like with dictionaries, it is convenient to index lists without catching exceptions. Adding an import for this most basic functionality is slightly tedious, and I can't imagine it would break anything to add a list.get method. |

This idea has been discussed before and was rejected. While get() makes sense and has valid use cases for dictionaries which use key based lookups, there isn't a parallel for lists. In general, we do just fine without list.get(). Also, it seems that other languages have mostly made the same decision in this regard. Thank you for the suggestion though. |

There really are valid use cases for this. Would you please refer me to this previous discussion? In a particular small to medium sized Python repository of ~10k lines, list get is used 23 times, whereas other list builtin methods are used far less (for example list.pop is used once, though dict.pop is used 18 times). I would be happy to go into specific examples. |
