For example, let's say I have val x = List(1, 2, 3) and I want to convert this into (1, 2, 3) . How can I do this? 回答1: You can't do this in a typesafe way. Why? Because in general we can't know the length of a list until runtime. But the "length" of a tuple must be encoded in its type, and hence known at compile time. For example, (1,'a',true) has the type (Int, Char, Boolean) , which is sugar for Tuple3[Int, Char, Boolean] . The reason tuples have this restriction is

For example: >>> d = {'a': 1, 'b': {'c': 2}, 'd': ["hi", {'foo': "bar"}]} Should be accessible in this way: >>> x = dict2obj(d) >>> x.a 1 >>> x.b.c 2 >>> x.d[1].foo bar I think, this is not possible without recursion, but what would be a nice way to get an objectstyle for dicts? 回答1: Update: In Python 2.6 and onwards, consider whether the namedtuple data structure suits your needs: >>> from collections import namedtuple >>> MyStruct =

At first, the error stated that I was attempting to subtract a string from an integer in this part of the code: balance - strength . Obviously that was wrong so I fixed it with strength = int(strength) ... but now I am getting this error which I have never seen before(new programmer) and I am stumped on what exactly it is trying to tell me and how I fix it. Here is my code

How do I delete these characters all at once? 回答1: dos2unix is a commandline utility that will do this, or :%s/^M//g will if you use Ctrl - v Ctrl - m to input the ^M, or you can :set ff=unix and vim will do it for you. Docs on the 'fileformat' setting are here , and the vim wiki has a comprehensive page on line ending conversions . Alternately, if you move files back and forth a lot, you might not want to convert them, but rather to do :set ff=dos , so vim will know it's a

How can I convert an ordinary System.Security.SecureString to System.String? I'm sure many of you who are familiar with SecureString are going to respond that one should never transform a SecureString to an ordinary .NET string because it removes all security protections. I know . But right now my program does everything with ordinary strings anyway, and I'm trying to enhance its security and although I'm going to be using an
