This is usually with the cases with character to string conversion. This type of task is usually required in the development domain to merge the names into one element. Let’s discuss certain ways in which this can be performed. Method #1 : Using
Output: The original list is : ['I', 'L', 'O', 'V', 'E', 'G', 'F', 'G'] The list after merging elements : ['I', 'L', 'O', 'V', 'E', 'GFG'] Method #2 : Using
Output: The original list is : ['I', 'L', 'O', 'V', 'E', 'G', 'F', 'G'] The list after merging elements : ['I', 'L', 'O', 'V', 'E', 'GFG'] Let’s see how to concatenate two lists using different methods in Python. This operation is useful when we have numbers of lists of elements which needs to be processed in a similar manner. Method #1 : Using Naive Method In this method, we traverse the second list and keep appending elements in the first list, so that first list would have all the elements in both lists and hence would perform the append.
Output: Concatenated list using naive method : [1, 4, 5, 6, 5, 3, 5, 7, 2, 5] The most conventional method to perform the list concatenation, the use of “+” operator can easily add the whole of one list behind the other list and hence perform the concatenation.
Output: Concatenated list using + : [1, 4, 5, 6, 5, 3, 5, 7, 2, 5] Method #3 : Using list comprehension List comprehension can also accomplish this task of list concatenation. In this case, a new list is created, but this method is a one liner alternative to the loop method discussed above.
Output: Concatenated list using list comprehension: [1, 4, 5, 6, 5, 3, 5, 7, 2, 5]
Output: Concatenated list using list.extend() : [1, 4, 5, 6, 5, 3, 5, 7, 2, 5] Using * operator, this method is the new addition to list concatenation and works only in Python 3.6+. Any no. of lists can be concatenated and returned in a new list using this operator.
Output: Concatenated list using * operator : [1, 4, 5, 6, 5, 3, 5, 7, 2, 5]
Output: Concatenated list using itertools.chain() : [1, 4, 5, 6, 5, 3, 5, 7, 2, 5] How do you join two items in a list python?The most conventional method to concatenate lists in python is by using the concatenation operator(+). The “+” operator can easily join the whole list behind another list and provide you with the new list as the final output as shown in the below example.
How do you combine elements in a list?This operation is useful when we have numbers of lists of elements which needs to be processed in a similar manner.. Method #1 : Using Naive Method.. Method #2 : Using + operator.. Method #3 : Using list comprehension.. Method #4 : Using extend(). Method #5 : Using * operator.. Method #6 : Using itertools.chain(). How do you join a specific part of a list in python?To join specific list elements in Python:. Use list slicing to select the specific elements in the list.. Use the str. join() method to join the elements into a string.. Replace the list elements with the string.. |
