Python | How to sort a list of strings
Given a list of strings, the task is to sort that list based on given requirement. There are multiple scenarios possible while sorting a list of string, like –
- Sorting in alphabetical/reverse order.
- Based on length of string character
- Sorting the integer values in list of string etc.
Let’s discuss various ways to perform this task.
Example #1: Using sort() function.
Python3
# Python program to sort a list of stringslst = ['gfg', 'is', 'a', 'portal', 'for', 'Beginner']# Using sort() functionlst.sort()print(lst) |
Output:
['a', 'for', 'Beginner', 'gfg', 'is', 'portal']
Example #2: Using sorted() function.
Python3
# Python program to sort a list of stringslst = ['gfg', 'is', 'a', 'portal', 'for', 'Beginner']# Using sorted() functionfor ele in sorted(lst): print(ele) |
Output:
a for Beginner gfg is portal
Example #3: Sort by length of strings
Python3
# Python program to sort a list of stringslst = ['w3wiki', 'is', 'a', 'portal', 'for', 'Beginner']# Using sort() function with key as lenlst.sort(key = len)print(lst) |
Output:
['a', 'is', 'for', 'Beginner', 'portal', 'w3wiki']
Example #4: Sort string by integer value
Python3
# Python program to sort a list of stringslst = ['23', '33', '11', '7', '55']# Using sort() function with key as intlst.sort(key = int)print(lst) |
Output:
['7', '11', '23', '33', '55']
Example #5: Sort in descending order
Python3
# Python program to sort a list of stringslst = ['gfg', 'is', 'a', 'portal', 'for', 'Beginner']# Using sort() functionlst.sort(reverse = True)print(lst) |
Output:
['portal', 'is', 'gfg', 'Beginner', 'for', 'a']
