将元组列表转换为字符串Python [英] Converting lists of tuples to strings Python

问题描述

例如，我已经在python中编写了一个返回列表的函数

I've written a function in python that returns a list, for example

[(1,1),(2,2),(3,3)] 

但是我希望输出为字符串，这样我就可以将逗号替换为另一个字符，从而使输出为

But i want the output as a string so i can replace the comma with another char so the output would be

'1@1' '2@2' '3@3' 

有什么简单的方法吗?:) 感谢您提前提出的提示

Any easy way around this?:) Thanks for any tips in advance

推荐答案

这看起来像tuple的list，其中每个tuple具有两个元素.

This looks like a list of tuples, where each tuple has two elements.

' '.join(['%d@%d' % (t[0],t[1]) for t in l])

当然可以简化为:

' '.join(['%d@%d' % t for t in l])

甚至:

' '.join(map(lambda t: '%d@%d' % t, l))

l是您的原始list.这会为列表中的每个元组生成"number @ number"对.然后将这些对与空格(' ')连接起来.

Where l is your original list. This generates 'number@number' pairs for each tuple in the list. These pairs are then joined with spaces (' ').

当我第一次开始使用Python唤醒时，join语法对我来说有点奇怪，但是

The join syntax looked a little weird to me when I first started woking with Python, but the documentation was a huge help.
