可变的地狱 [英] variable hell
问题描述
嗨
我正在将一个列表打包成变量，出于某种原因，他们需要将
解压缩到变量中像a0，a1，a2 ......这样的名字直到aN
列表中的内容。
如何动态创建变量？
我正在寻找类似
的伪代码行如下：
a％s = str（value）
下面是mylist解包代码的片段
#next行从列表中的每一行剪下行尾字符
mylist = [line [： - 1] for mylist中的行]
表示索引，值为枚举（mylist）：
如果index == 0：
a0 = str（值）
打印" a0："，a0
elif index == 1：
a1 = str（价值）
打印" a1："，a1
谢谢

Hi
I am unpacking a list into variables, for some reason they need to be
unpacked into variable names like a0,a1,a2....upto aN whatever is
in the list.
How to create the variables dynamically ?
I am looking for something like
pseudo code line follows :
a%s = str(value)
here below is a snippet from the mylist unpack code
#next lines cut the end of line character from each line in the list
mylist = [line[:-1] for line in mylist]
for index,value in enumerate(mylist):
if index == 0 :
a0 = str(value)
print "a0 : ",a0
elif index == 1 :
a1 = str(value)
print "a1 : ",a1
Thanks

解释这个某种原因。这有点味道，而且要走的路是
使用dict将a_n映射到列表中的任何内容 - 不创建
变量。无论如何，你想如何访问生成的变量 -
特别是当你不知道有多少人在那里？b $ b是多少？显然，基于此不能编写代码。
问候，

Explain this "some reason". This smells, and the way to go would be to
use a dict mapping a_n to whatever is in the list - not creating
variables. How do you want to access generated variables anyway -
especially when you don''t have the faintest idea how many of them there
are? Obviously there can''t be code written based on that.

你可能做错了事。你的最终目标是什么？b $ b这个？可能有更好的方法。
同时，看看eval（）。

You''re probably doing things the wrong way. What is your ultimate goal
with this? There is probably a better way of doing it.
In the mean time, look at eval().
