Python - convert list of tuples to string

Question

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

I have:

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

and I want:

\"(1,2), (         


        

Answer 1

you might want to use something such simple as:

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

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

Answer 2

You can try something like this (see also on ideone.com):

myList = [(1,2),(3,4)]
print ",".join("(%s,%s)" % tup for tup in myList)
# (1,2),(3,4)

Answer 3

The most pythonic solution is

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

tuple_strings = ['(%s, %s)' % tuple for tuple in tuples]

result = ', '.join(tuple_strings)

Answer 4

How about

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

Answer 5

I think this is pretty neat:

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

Try it, it worked like a charm for me.

Answer 6

How about:

>>> tups = [(1, 2), (3, 4)]
>>> ', '.join(map(str, tups))
'(1, 2), (3, 4)'
