Python | Ways to sort letters of string alphabetically
Given a string of letters, write a python program to sort the given string in an alphabetical order.
Examples:
Input : PYTHON Output : HNOPTY Input : Geeks Output : eeGks
When string is in same case –
Method #1 : Using sorted() with join()
# Python3 program to sort letters # of string alphabetically def sortString(str): return ''.join(sorted(str)) # Driver code str = 'PYTHON'print(sortString(str)) |
chevron_right
filter_none
Output:
HNOPTY
Method #2 : Using sorted() with accumulate()
# Python3 program to sort letters # of string alphabetically from itertools import accumulate def sortString(str): return tuple(accumulate(sorted(str)))[-1] # Driver code str = 'PYTHON'print(sortString(str)) |
chevron_right
filter_none
Output:
HNOPTY
Method #3 : Using sorted() with reduce()
Another alternative is to use reduce() method. It applies a join function on the sorted list using ‘+’ operator.
# Python3 program to sort letters # of string alphabetically from functools import reduce def sortString(str): return reduce(lambda a, b : a + b, sorted(str)) # Driver code str = 'PYTHON'print(sortString(str)) |
chevron_right
filter_none
Output:
HNOPTY
When string is in different cases –
Using sorted() with join()
# Python3 program to sort letters # of string alphabetically from itertools import accumulate def sortString(str): return "".join(sorted(str, key = lambda x:x.lower())) # Driver code str = 'Geeks'print(sortString(str)) |
chevron_right
filter_none
Output:
eeGks
