Question

16.42 Lab 13B: Palindromes with Files Overview This is a demonstration of reading and writing files. Objectives Be able to read from an input file, perform string manipulation on each line of the file, and write to an output file. Provided input file: A single input file named myinput.txt is provided that contains a few lines of text. bob sees over the moon never odd or even statistics dr awkward

In Python Please!

Here is the completed code for this problem. Comments are included, go through it, learn how things work and let me know if you have any doubts or if you need anything to change. If you are satisfied with the solution, please rate the answer. If not, PLEASE let me know before you rate, I’ll help you fix whatever issues. Thanks

Note: Please maintain proper code spacing (indentation), just copy the code part and paste it in your compiler/IDE directly, no modifications required.

#code

#opening input file in read mode, output file in write mode
input_file=open('myinput.txt','r')
output_file=open('myoutput.txt','w')

#looping through each line in input_file
for line in input_file:
    #removing trailing/leading newline characters from the line
    line=line.strip()
    #removing all spaces from line to create a new variable
    nospaces=line.replace(' ','')
    #nospaces[::-1] returns the reverse of a string using slicing. if you do not want to use
    #slicing, let me know, i'll replace this with a loop
    #checking nospaces equals the reverse of it
    if nospaces==nospaces[::-1]:
        #palindrome, writing to output_file and console
        output_file.write('palindrome\n')
        print('{} ==> {}'.format(line,'palindrome'))
    else:
        #not palindrome, writing to output_file and console
        output_file.write('not a palindrome\n')
        print('{} ==> {}'.format(line, 'not a palindrome'))

#closing both files, saving changes in output_file
input_file.close()
output_file.close()

#output

bob ==> palindrome
sees ==> palindrome
over the moon ==> not a palindrome
never odd or even ==> palindrome
statistics ==> not a palindrome
dr awkward ==> palindrome
