Sagot :
Answer:
filename = input("Enter file name with extension:")
words = []
with open(filename, "r") as file:
# read the file line by line, with each line an item in the returned list
line_list = file.readlines()
# loop through the list to get the words from the strings
for line in line_list:
word_list = line.split(" ")
for i in word_list:
words.append(i)
# use the set() to get the unique items of the list as a set
# and convert it back to a list, then display the list.
su_words = set(words)
unique_words = list(su_words)
print(unique_words)
Explanation:
The python program gets the file name from the user input method. The with keyword is used to open and read the file which is read line by line as a list of strings (each line is a string). The for loop is used to append each word to the words list and the set() function cast the words list to a set of unique words. The set is in turn converted back to a list and displayed.
