Question

Write a python program that does the following:

Prompt for a file name of text words.
Words can be on many lines with multiple words per line.

Read the file and convert the words to a list.

Call a function you created called list_to_once_words(), that takes a list as an argument and returns a list that contains only words that occurred once in the file.

Print the results of the function with an appropriate description.

Think about everything you must do when working with a file.

Answer 1

def list_to_once_words(list):
     once_words=[]#empty list
     for i in range(0,len(list)):
         temp=0
         for j in range(0,len(list)):
             #checking the condition with case sensitive
             if(list[i].lower()==list[j].lower() and i!=j):
                 temp=1
                 break
         if(temp==0):
             #appending to the list
            once_words.append(list[i])
   
     return once_words#returning the list
               
               
#taking filename from the user
file_name=input("Enter the name of the file:")
list=[]
# opening the text file
with open(file_name,'r') as file:
   # reading each line   
    for line in file:
       # reading each word       
        for word in line.split():
            # appending the words          
            list.append(word)
print("original list:",list)#
result=list_to_once_words(list)
print("The list with only words that occurred once in the file:",result)
