# Python – Get Nth column elements in Tuple Strings

• Last Updated : 10 Oct, 2022

Yet another peculiar problem which might not be common, but can occur in python programming while playing with tuples. Since tuples are immutable, they are difficult to manipulate and hence knowledge of possible variation solutions always helps. This articles solves problem of extracting only the Nth index element of each string in tuple. Let’s discuss certain ways in which this problem can be solved. Method #1 : Using list comprehension Almost every problem can be solved using list comprehension as a shorthand to naive approach and this problem isn’t an exception. In this, we just iterate through each list picking just the Nth index element to build the resultant list.

## Python3

 `# Python3 code to demonstrate``# Nth column in Tuple Strings``# using list comprehension` `# initializing tuple``test_tuple ``=` `(``'GfG'``, ``'for'``, ``'Geeks'``)` `# initializing N``N ``=` `1` `# printing original tuple``print``("The original ``tuple` `: " ``+` `str``(test_tuple))` `# using list comprehension``# Nth column in Tuple Strings``res ``=` `list``(sub[N] ``for` `sub ``in` `test_tuple)` `# print result``print``("The Nth index string character ``list` `: " ``+` `str``(res))`

Output :

```The original tuple : ('GfG', 'for', 'Geeks')
The Nth index string character list : ['f', 'o', 'e']```

Method #2 : Using next() + zip() This particular task can also be performed using the combination of above two in more efficient way, using the iterators to do this task. The zip function can be used bind together the string elements.
