Question

Writing a program in Python that reads a text file and organizes the words in the file into a list without repeating words and in all lowercase.

Here is what I have

#This program takes a user input file name and returns each word in a list
#and how many different words are in the program.
while True:   #While loop to loop program
    words = 0
    #list1 = ['Programmers','add','an','operating','system','and','set','of','applications','to','the','hardware',
         # 'we','end','up','with','a','Personal','Digital','Assistant','that','is','quite','helpful','capable',
          #'helping','us','do','many','different','things']
  
    try:
        fname = input('Please enter the file name to open:')
        fhand = open(fname)
        list1 = list()
      
  
        for line in fhand: #Iteration over each line
            words = line.split()
            list1.append(words)
            #words = [words.lower() for words in list1]
          
        print('list',list1)
        print('words',words)

        sorted_list = sorted(words)
        print(sorted_list)
        print('File',fname,'has',len(list1),'different words.')
                      
        ans = input("Do you want try again? y/n: ") #asking user to contiune
        
        if ans == 'y' or ans == 'Y':
            continue
        else:
            if ans == 'n' or ans == 'N':
                print('Goodbye')
                break   
    except:
        print('File cannot be opened:', fname)
        continue

while True: #While loop to loop program
try:

#Add to list
list1.extend([word.lower() for word in words])
