How to sort the letters in a string alphabetically in Python

Question

Is there an easy way to sort the letters in a string alphabetically in Python   So for   a    ZENOVW    I would like to return    ENOVWZ

User · Answer

the code can be used to sort string in alphabetical order without using any inbuilt function of python

k = input("Enter any string again ")

li = []
x = len(k)
for i in range (0,x):
    li.append(k[i])

print("List is : ",li)


for i in range(0,x):
    for j in range(0,x):
        if li[i]<li[j]:
            temp = li[i]
            li[i]=li[j]
            li[j]=temp
j=""

for i in range(0,x):
    j = j+li[i]

print("After sorting String is : ",j)

gt  gt  gt  a    ZENOVW   gt  gt  gt  b   sorted a   gt  gt  gt  print b   E    N    O    V    W    Z     sorted returns a list  so you can make it a string again using join    gt  gt  gt  c      join b    which joins the items of b together with an empty string    in between each item    gt  gt  gt  print c  ENOVWZ

Python functionsorted returns ASCII based result for string    INCORRECT  In the example below  e and d is behind H and W due it s to ASCII value    gt  gt  gt a    Hello World    gt  gt  gt    join sorted a       HWdellloor    CORRECT  In order to write the sorted string without changing the case of letter  Use the code    gt  gt  gt  a    Hello World    gt  gt  gt     join sorted a key lambda x x lower        deHllloorW    If you want to remove all punctuation and numbers  Use the code    gt  gt  gt  a    Hello World    gt  gt  gt     join filter lambda x x isalpha    sorted a key lambda x x lower       deHllloorW

You can use reduce   gt  gt  gt  a    ZENOVW   gt  gt  gt  reduce lambda x y  x y  sorted a    ENOVWZ

Really liked the answer with the reduce   function  Here s another way to sort the string using accumulate     from itertools import accumulate s    mississippi  print tuple accumulate sorted s    -1     sorted s  -    i    i    i    i    m    p    p    s    s    s    s    tuple accumulate sorted s   -    i    ii    iii    iiii    iiiim    iiiimp    iiiimpp    iiiimpps    iiiimppss    iiiimppsss    iiiimppssss    We are selecting the last index  -1  of the tuple
