Sometimes, while working with Python, we can have a problem in which we need to perform the sort operation in all the Strings that are present in a list. This problem can occur in general programming and web development. Let’s discuss certain ways in which this problem can be solved.
Method #1 : Using list comprehension + sorted() + join()
This is one way in which this problem can be solved. In this, we use sorted() functionality to perform sort operation and join() is used to reconstruct the string list.
# Python3 code to demonstrate working of # Sort Strings in String list # using list comprehension + sorted() + join() # initialize list test_list = [ 'gfg' , 'is' , 'good' ] # printing original list print ( "The original list : " + str (test_list)) # Sort Strings in String list # using list comprehension + sorted() + join() res = [''.join( sorted (ele)) for ele in test_list] # printing result print ( "List after string sorting : " + str (res)) |
The original list : ['gfg', 'is', 'good'] List after string sorting : ['fgg', 'is', 'dgoo']
Method #2 : Using map() + sorted() + join()
+ lambda
The combination of above method can also be used to perform this task. In this, we perform the functionality of traversal using map() and lambda rather than list comprehension.
# Python3 code to demonstrate working of # Sort Strings in String list # using map() + sorted() + join() + lambda # initialize list test_list = [ 'gfg' , 'is' , 'good' ] # printing original list print ( "The original list : " + str (test_list)) # Sort Strings in String list # using map() + sorted() + join() + lambda res = list ( map ( lambda ele: "".join( sorted (ele)), test_list)) # printing result print ( "List after string sorting : " + str (res)) |
The original list : ['gfg', 'is', 'good'] List after string sorting : ['fgg', 'is', 'dgoo']
