This is a quite simple problem but can have a good amount of application due to certain constraints of python language. Because tuples are immutable, they are not easy to process whereas lists are always a better option while processing. Let’s discuss certain ways in which we can convert a list of tuples to list of list.
Method #1 : Using list comprehension
This can easily be achieved using the list comprehension. We just iterate through each list converting the tuples to the list.
# Python3 code to demonstrate# convert list of tuples to list of list# using list comprehension # initializing list test_list = [(1, 2), (3, 4), (5, 6)] # printing original list print("The original list of tuples : " + str(test_list)) # using list comprehension# convert list of tuples to list of listres = [list(ele) for ele in test_list] # print resultprint("The converted list of list : " + str(res)) |
The original list of tuples : [(1, 2), (3, 4), (5, 6)] The converted list of list : [[1, 2], [3, 4], [5, 6]]
Method #2 : Using map() + list
We can use the combination of map function and list operator to perform this particular task. The map function binds each tuple and converts it into list.
# Python3 code to demonstrate# convert list of tuples to list of list# using map() + list # initializing list test_list = [(1, 2), (3, 4), (5, 6)] # printing original list print("The original list of tuples : " + str(test_list)) # using map() + list# convert list of tuples to list of listres = list(map(list, test_list)) # print resultprint("The converted list of list : " + str(res)) |
The original list of tuples : [(1, 2), (3, 4), (5, 6)] The converted list of list : [[1, 2], [3, 4], [5, 6]]
