Python | Convert Integral list to tuple list

Sometimes, while working with data, we can have a problem in which we need to perform type of interconversions of data. There can be a problem in which we may need to convert integral list elements to single element tuples. Let’s discuss certain ways in which this task can be performed.

Method #1 : Using list comprehension
List comprehension can be used as a shorthand method to solve this particular problem. In this, we iterate through the list and convert each integer element into a tuple object.

 `# Python3 code to demonstrate working of ` `# Convert Integral list to tuple list ` `# using list comprehension ` ` `  `# initialize list  ` `test_list ``=` `[``1``, ``4``, ``6``, ``8``, ``9``] ` ` `  `# printing original list  ` `print``(``"The original list : "` `+` `str``(test_list)) ` ` `  `# Convert Integral list to tuple list ` `# using list comprehension ` `res ``=` `[(ele, ) ``for` `ele ``in` `test_list] ` ` `  `# printing result ` `print``(``"List after conversion to tuple list : "` `+` `str``(res)) `

Output :

The original list : [1, 4, 6, 8, 9]
List after conversion to tuple list : [(1, ), (4, ), (6, ), (8, ), (9, )]

Method #2 : Using `zip() + list()`
This is the simplest method to perform this particular task. The `zip()` when applied to list of integers, it converts each element to tuple. It returns a zip object and hence it has to converted back to list using `list()`.

 `# Python3 code to demonstrate working of ` `# Convert Integral list to tuple list ` `# using zip() + list() ` ` `  `# initialize list  ` `test_list ``=` `[``1``, ``4``, ``6``, ``8``, ``9``] ` ` `  `# printing original list  ` `print``(``"The original list : "` `+` `str``(test_list)) ` ` `  `# Convert Integral list to tuple list ` `# using zip() + list() ` `res ``=` `list``(``zip``(test_list)) ` ` `  `# printing result ` `print``(``"List after conversion to tuple list : "` `+` `str``(res)) `

Output :

The original list : [1, 4, 6, 8, 9]
List after conversion to tuple list : [(1, ), (4, ), (6, ), (8, ), (9, )]
