Python 打印不带括号的集合列表 [英] Python print list of sets without brackets

问题描述

我有一个集合列表(使用 Python).有没有办法在没有set([])"的情况下打印它，而只输出它们所持有的实际值?

I have a list of sets (using Python). Is there a way to print this without the "set([])" stuff around it and just output the actual values they are holding?

现在我为列表中的每个项目得到这样的东西

Right now I'm getting somthing like this for each item in the list

 set(['blah', 'blahh' blahhh')]

我希望它看起来更像这样

And I want it to look more like this

blah,blahh,blahhh

推荐答案

方法很多，但我第一个想到的是:

Lots of ways, but the one that occurred to me first is:

s = set([0,1])
", ".join(str(e) for e in s)

将集合中的所有内容转换为字符串，并用逗号将它们连接在一起.显然，您对显示的偏好可能会有所不同，但您可以很高兴地将其传递给 print.应该在 python 2 和 python 3 中工作.

Convert everything in the set to a string, and join them together with commas. Obviously your preference for display may vary, but you can happily pass this to print. Should work in python 2 and python 3.

对于集合列表:

l = [{0,1}, {2,3}]
for s in l:
    print(", ".join(str(e) for e in s))
