Question

python:

Read the list of strings as separate lines from a text file whose file name is provided at run-time (Dr. Hanna's input file E29.txtPreview the document).

Write a function that takes a list of strings and outputs them, one per line, in a rectangular frame. For

example the list

[ "Hello", "World", "in", "a", "frame" ]

gets output as

*********

* Hello *

* World *

* in *

* a *

* frame *

*********

Answer 1

# reads the file and stores each word seprately in the list

def getList(filename):

    # open the file in read mode

    fptr = open(filename , 'r')

   

    # store the text of the file in strng

    strng = fptr.read()

   

    arr = []

   

    # read the text line by line

    for line in strng.split('\n'):

   

        # read word by word removing all the special characters

        for word in line.split(' '):

            arr.append(word)

           

    return arr

   

def show_rectangular_frame(arr):

    # store the length o the longest string in arr

    max_len = 0

   

    # get the length of longest string

    for i in arr:

   

        if len(i) > max_len:

       

            max_len = len(i)

           

    temp = '*' * ( max_len + 5 )

   

    print(temp)

   

    for i in arr:

   

        print('*', i, ' *')

       

    print(temp)

       

filename = input('Enter the name of the file : ')

arr = getList(filename)

show_rectangular_frame(arr)
