Python - 将元组列表转换为字符串

2022-01-19 00:00:00 python list tuples string-formatting

问题描述

将元组列表转换为字符串的最 Pythonic 方式是什么?

Which is the most pythonic way to convert a list of tuples to string?

我有:

[(1,2), (3,4)]

我想要:

"(1,2), (3,4)"

我的解决方案是:

l=[(1,2),(3,4)]
s=""
for t in l:
    s += "(%s,%s)," % t
s = s[:-1]

有没有更 Pythonic 的方式来做到这一点?

Is there a more pythonic way to do this?

解决方案

你可能想使用如下简单的东西:

you might want to use something such simple as:

>>> l = [(1,2), (3,4)]
>>> str(l).strip('[]')
'(1, 2), (3, 4)'

.. 这很方便，但不能保证正常工作

.. which is handy, but not guaranteed to work correctly
