How To Join Many "listed" Tuples Into One Tuple In Python?

There are few answers for the problem on in Python, How to join a list of tuples into one list?, How to merge two tuples in Python?, How To Merge an Arbitrary Number of Tuples in P

Solution 1:

tuple(ast.literal_eval(x) for x in my_open_file if x.strip())

I suppose ...

Solution 2:

a = (1, 5)

b = (5, 3)

c = (10, 3)

d = (5, 4)

e = (1, 3)

f = (2, 5)

g = (1, 5)

tul = (a, b, c, d, e, f, g)

print(tul)

Solution 3:

list comprehension as mentioned in your linked answers works with tuple() as well:

print tuple((1,2) for x in xrange(0, 10))

Leaving off the "tuple" or "list" at the beginning will return a generator.

print ((1,2) for x in xrange(0, 10))

Using [] instead of () is short-hand for list:

print [(1,2) for x in xrange(0, 10)]

The evaluation of the for statement is returning a generator, while the keywords or bracket are telling python to unpack it into that type.

Solution 4:

Here is my problem: I want to know how many times a tuple appears in my 'result'. So I did this:

from collections import Counter
liste = [1,2,3,5,10]
liste2 = [[1,2,3,5,10], [1,2], [1,5,10], [3,5,10], [1,2,5,10]]
for elt in liste2:
    syn = elt # identify each sublist of liste2 as syn
    nTuple = len(syn)   # number of elements in the synfor i in liste:
        myTuple = ()
        if synset.count(i): # check if an item of liste is in liste2
        myTuple = (i, nTuple)
        iflen(myTuple) == '0': # remove the empty tuplesdel(myTuple)
        else:
            result = [myTuple] 
            c = Counter(result)
            for item in c.items():
                print(item)

and I got these results:

((1, 5), 1)

((2, 5), 1)

((3, 5), 1)

((5, 5), 1)

((10, 5), 1)

((1, 2), 1)

((2, 2), 1)

((1, 3), 1)

((5, 3), 1)

((10, 3), 1)

((3, 3), 1)

((5, 3), 1)

((10, 3), 1)

((1, 4), 1)

((2, 4), 1)

((5, 4), 1)

((10, 4), 1)

Instead of having some elts N times (e.g ((5, 3), 1) and ((10, 3), 1) appear twice), I would like to have a tuple(key,value) where value = the number of times key appears in 'result'. That why I thought I can join my listed tuples in one tuple before using Counter.

I would like to get 'result' like this:

((1, 5), 1)

((2, 5), 1)

((3, 5), 1)

((5, 5), 1)

((10, 5), 1)

((1, 2), 1)

((2, 2), 1)

((1, 3), 1)

((5, 3), 2)

((10, 3), 2)

((3, 3), 1)

((1, 4), 1)

((2, 4), 1)

((5, 4), 1)

((10, 4), 1)
