Joining elements together in a list of tuples

The input:

z = ", "
y = " "
chands = {'theboard': [('Diamonds', 'Four'), ('Clubs', 'Three'), ('Clubs', 'King'), ('Clubs', 'Two'), ('Hearts', 'Jack')]}

My expected output:

'Diamonds Four, Clubs Three, Clubs King, Clubs Two, Hearts Jack'

I've tried: 

print chands["theboard"][0][0]+y+chands["theboard"][0][1]+z+chands["theboard"][1][0]+y+chands["theboard"][1][1]+z+chands["theboard"][2][0]+y+chands["theboard"][2][1]

Is there a better way to print this?

IIUC, use map + str.join, once on y and once more on z - 

>>> z.join(map(y.join, chands['theboard']))
'Diamonds Four, Clubs Three, Clubs King, Clubs Two, Hearts Jack'

If you want to join just the first 3 tuples, you can index chands and slice the result - 

>>> z.join(map(y.join, chands['theboard'][:3]))
'Diamonds Four, Clubs Three, Clubs King'

Another way to do this with a list comprehension would be - 

>>> z.join([y.join(x) for x in chands['theboard'][:3]])
'Diamonds Four, Clubs Three, Clubs King'
