Question

Write a program that inputs a text file. The program should print the unique words in the file in alphabetical order. Uppercase words should take precedence over lowercase words. For example, 'Z' comes before 'a'.

Answer 1

Answer:

unique = []

with open("file_name.txt", "r") as file:

   lines = file.readlines()

   for line in lines:

       # assuming comma is the only delimiter in the file

       words = line.split()

       for word in words:

           word = word.strip()

           if word not in unique:

               unique.append(word)

unique = sorted(unique)

print(unique)

Explanation:

The python module opens a file using the 'with' keyword (the file closes automatically at the end end of the indentation) and the open built-in function and reads the content of the open file as a list of lines of the content.

Each line is split into a list and the unique words are collected and stored in the unique list variable.
