Python - convert list of tuples to string
提问by ssoler
Which is the most pythonic way to convert a list of tuples to string?
将元组列表转换为字符串的最pythonic 方法是什么？
I have:
我有：
[(1,2), (3,4)]
and I want:
而且我要：
"(1,2), (3,4)"
My solution to this has been:
我对此的解决方案是：
l=[(1,2),(3,4)]
s=""
for t in l:
s += "(%s,%s)," % t
s = s[:-1]
Is there a more pythonic way to do this?
有没有更pythonic的方法来做到这一点？

you might want to use something such simple as:
你可能想使用一些简单的东西，比如：
>>> l = [(1,2), (3,4)]
>>> str(l).strip('[]')
'(1, 2), (3, 4)'
.. which is handy, but not guaranteed to work correctly
.. 这很方便，但不能保证正常工作

You can try something like this (see also on ideone.com):
您可以尝试这样的操作（另请参见 ideone.com）：
myList = [(1,2),(3,4)]
print ",".join("(%s,%s)" % tup for tup in myList)
# (1,2),(3,4)

How about
怎么样
l = [(1, 2), (3, 4)]
print repr(l)[1:-1]
# (1, 2), (3, 4)

How about:
怎么样：
>>> tups = [(1, 2), (3, 4)]
>>> ', '.join(map(str, tups))
'(1, 2), (3, 4)'

Three more :)
还有三个:)
l = [(1,2), (3,4)]
unicode(l)[1:-1]
# u'(1, 2), (3, 4)'
("%s, "*len(l) % tuple(l))[:-2]
# '(1, 2), (3, 4)'
", ".join(["%s"]*len(l)) % tuple(l)
# '(1, 2), (3, 4)'

I think this is pretty neat:
我认为这很整洁：
>>> l = [(1,2), (3,4)]
>>> "".join(str(l)).strip('[]')
'(1,2), (3,4)'
Try it, it worked like a charm for me.
试试吧，它对我来说就像一个魅力。

The most pythonic solution is
最pythonic的解决方案是
tuples = [(1, 2), (3, 4)]
tuple_strings = ['(%s, %s)' % tuple for tuple in tuples]
result = ', '.join(tuple_strings)
