Convert List of Tuples to List of List in Python
Convert List of Tuples to List of List in Python:
Given a list of tuples, write a Python program to convert it into a list of list. we can perform this operation using various Methods.
Example :
- a=[ ( 1, 2) , ( 3 ,4) ]
- a = [ [1,2] ,[3,4 ] ]
Convert List of Tuples to List of List
Converting a list of tuples to a list of lists in Python is a common operation that allows you to transform your data structure for various purposes. This task is relatively straightforward and can be accomplished using a variety of methods.
Method 1 :
This can easily be achieved using the list comprehension. We just iterate through each tuple of the list convert the tuples to the list.
#Python Program
# Python code to convert list of tuples into list of list
# List of tuple
tup = [('A', 2), ('B', 4), (5, 6)]
print('The original list of tuple is :' , tup)
# using list comprehension
# convert list of tuples to list of list
res = [list(ele) for ele in tup]
print("The list of list :" ,res) Output :
The orignal list of tuple is : [('A', 2), ('B', 4), (5, 6)]
The list of list : [['A', 2], ['B', 4], [5, 6]]
Method 2 :
We can use the map function and list operator to perform this particular task. The map function binds each tuple and converts it into a list.
#Python Program
# Python code to convert list of tuples into list of list
# List of tuple
tup = [('A', 2), ('B', 4), (5, 6)]
print('The orignal list of tuple is :' , tup)
# using map() + list
# convert list of tuples to list of list
res = list(map(list, tup))
print("The list of list :" ,res)
Output :
The orignal list of tuple is : [('A', 2), ('B', 4), (5, 6)]
The list of list : [['A', 2], ['B', 4], [5, 6]] Prime Course Trailer
