需要在 Python 中创建帮助变量 [英] need help-variable creation in Python

问题描述

我想将变量创建为 a1,a2,a3...a10.为此，我使用了 for 循环.随着循环中的变量递增，我需要像上面一样创建一个变量.

I want to create variables as a1,a2,a3...a10. For that I used a for loop. As the variable in loop increments I need to create a variable as above.

谁能给我一个想法?

在创建时，我还需要能够为它们赋值.

At the time of creation I also need to be able to assign values to them.

这就是我遇到语法错误的地方.

That's where I'm getting syntax error.

推荐答案

按照 S.Lott 所说的，你也可以使用 dict，如果你真的需要唯一的名称并且项目的顺序并不重要:

Following what S.Lott said, you can also use a dict, if you really nead unique names and that the order of the items is not important:

data = {}
for i in range(0, 10):
  data['a%d' % i] = i

>>>data
{'a1': 1, 'a0': 0, 'a3': 3, 'a2': 2, 'a5': 5, 'a4': 4, 'a7': 7, 'a6': 6, 'a9': 9, 'a8': 8}

我想补充一点，像您想要的那样自动创建变量是非常危险的，因为您可能会覆盖可能已经存在的变量.

I would add that this is very dangerous to automate variable creation like you want to do, as you might overwrite variables that could already exist.
