Question

Use the Python programming language to complete below (I need the New Answer for this, and please provide the screenshot of the source code. Thank you!):

• Write a program to input an uncertain string S of words and space/tab
  • Remove space/tab in S
  • Remove identical words
  • Sort all words in the order of a-z
  • Print the output strings
• Example:
  • Input String: "hello world and practice makes perfect and hello world again"
  • Output String: "again and hello makes perfect practice world"
• Tips:
  • use set to remove identical words,
  • use sorted() to sort words
  • use split() to remove space

Answer 1

string =input("Enter a string\n")#Input a string
a_list = string.split()#splitting it into list to remove extra spaces and tabs
new_string = " ".join(a_list)#string without tabs and spaces
l = new_string.split() #Splitting the new string 
k = []
for i in l: #removing identical words
    if (new_string.count(i)>1 and (i not in k)or new_string.count(i)==1): 
        k.append(i) 
new_string=' '.join(k) #new string after removing identical words
st=new_string.split(" ")
st.sort()#sorting in alphabetical order
res=" ".join(st)
print(res)#printinh the final output
