Python | Convert Integral list to tuple list

• Last Updated : 11 Nov, 2019

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 comprehensionres = [(ele, ) for ele in test_list]  # printing resultprint("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 resultprint("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, )]
