Question

** Language Used : Python **

PART 2 : Create a list of unique words

This part of the project involves creating a function that will manage a List of unique strings. The function is passed a string and a list as arguments. It passes a list back.

1. The function to add a word to a List if word does not exist in the List. If the word does exist in the List, the function does nothing.

2. Create a test program that takes a string as input and then calls the function over and over until the user enters "Done." If the string "Done" is entered, the program sorts the list and prints it out line by line.

PART 4: Parse a file into a list of unique words

The goal of this part is to create a unique list of only the words in the document and not the other characters.

1. In this part of the project, each team should read their file into a list and then iterate through the list, line by line, spliting the lines into words in a list. Before splitting the line into parts, the data cleaning function created in Part 1 should be called to remove all unwanted characters from the line.
2. Then use the function created in Part 2 to to add those words to a list of unique words.
3. Words should all be converted to uppercase before being addded into the List so that "Green" and "green" are considered the same. Also, any words that begin as all caps or as all numeric should not be added to the list.
4. Finally, once the entire text is processed, print out the contents of the list line by line. If you notice any characters that should have been removed, go back and add them to your file in Part 3 using the keyboard.
5. The successful projects will only have words in their output. There will be no special characters or numbers.

Answer 1

Here is the code,

For Part 2 :

def fun(str, list):
    for word in list:
        if word == str:
            return list
    list.append(str)
    return list

def main():
    list = []
    flag = True;
    while flag:
        str = input("Enter string : ")
        if str == 'Done':
            flag = False
        else:
            list = fun(str, list)
    list.sort()
    for word in list:
        print(word)
        
if __name__=="__main__":
    main()

Output :

Part 4 is incomplete, so please specify part 1 as well to complete it.
