Converting list of tuple to list

[Ganesh Pal]

Hello Team,



I have a list of tuple say   [(1, 2, 1412734464L, 280), (2, 5, 1582956032L,
351), (3, 4, 969216L, 425)] .  I need to convert the above as
['1,2,1412734464:280',
'2,5,1582956032:351', '3,4,969216:425']



Here is my Solution , Any  suggestion or optimizations are welcome .



Solution 1:



>>> list_tuple = [(1, 2, 1412734464L, 280), (2, 5, 1582956032L, 351), (3,
4, 969216L, 425)]

>>> expected_list = []

>>> for elements in list_tuple:

...     element = "%s,%s,%s:%s" % (elements)

...     expected_list.append(element)

...

>>> expected_list

['1,2,1412734464:280', '2,5,1582956032:351', '3,4,969216:425']





Solution 2:

>>> list_tuple = [(1, 2, 1412734464L, 280), (2, 5, 1582956032L, 351), (3,
4, 969216L, 425)]

>>> expected_list = []

>>> for i in range(len(list_tuple)):

...     element = list_tuple[i]

...     ex_element = "%s,%s,%s:%s" % (element[0], element[1], element[2],
element[3])

...     expected_list.append(ex_element)

...

>>> expected_list

['1,2,1412734464:280', '2,5,1582956032:351', '3,4,969216:425']

I know I should have not used len(range()) in  Solution 2, any more error
please let me know  , I am a Linux user on Python 2.7
