Sort the words

Problem to sort words by s1 alphabetical order.

input: s1="k" s2="welcome to mycrazycoding family"

if s1='k', the alphabetical order start with 'k' so k,l,m,n,....z,a,b,c,d,e,...j. 

The final output is "mycrazycoding to welcome family".

Example-1:

Input    : s1 = "k"  s2 = "welcome to mycrazycoding family"
Output   : mycrazycoding to welcome family

Example-2:

Input    : s1 = "j"  s2 = "stop worrying and start living"
Output   : living stop start worrying and

Solution

s1 = "k"

s2 = "welcome to mycrazycoding family"

s3 = s2.split()

a = ord(s1)

b = ord("z")

c = ord("a")

d = ""

k = ""

for i in range(a,b+1):

    d += chr(i)

for j in range(c,a):

    d += chr(j)

for x in d:

    for y in s3:

        if(x==y[0]):

            k += y

            k += " "
            
print(k.strip())

Output

mycrazycoding to welcome family
