Python | Scramble words from a text file
Last Updated :

Given some data in a text file, the task is to scramble the text and output in a separate text file. So, we need to write a Python program that reads a text file, scrambles the words in the file and writes the output to a new text file.
Rules to be followed:
- Words less than or equal to 3 characters need not be scrambled.
- Don’t scramble first and last char, so Scrambling can become Srbmnacilg or Srbmnailcg or Snmbracilg, i.e. letters except first and last can be scrambled in any order.
- Punctuation at the end of the word to be maintained as is i.e. “Surprising, ” could become “Spsirnirug, ” but not “Spsirn, irug”.
- Following punctuation marks are to be supported – Comma Question mark, Full stop, Semicolon, Exclamation.
- Do this for a file and maintain sequences of lines.
On executing the program, it should prompt the user to enter input file name and generate an output file with scrambled text. The output file should be named by appending the word “Scrambled” to the input file name.
Example:
Input : MyFile.txt ->
Scrambling words is very
interesting. Because even
if they are scrambled, it
doesn't impact our
reading. Because we don't
read letter by letter, we
read the word as a whole.
Output : MyFileScrambled.txt ->
Srbmnacilg words is very
itrensientg. Bscauee even
if tehy are srelabcmd, it
dosn'et ipcmat our
raidneg. Bacusee we dn'ot
raed lteetr by letetr, we
raed the word as a wolhe.
Below is the implementation :
Python3
import random
punct = (".", ";", "!", "?", ",")
count = 0
new_word = ""
inputfile = input("Enter input file name:")
with open(inputfile, 'r') as fin:
for line in fin.readlines():
for word in line.split():
if len(word) > 3:
if word.endswith(punct):
word1 = word[1:-2]
word1 = random.sample(word1, len(word1))
word1.insert(0, word[0])
word1.append(word[-2])
word1.append(word[-1])
else:
word1 = word[1:-1]
word1 = random.sample(word1, len(word1))
word1.insert(0, word[0])
word1.append(word[-1])
new_word = new_word + ''.join(word1) + " "
else:
new_word = new_word + word + " "
with open((inputfile[:-4] + "Scrambled.txt"), 'a+') as fout:
fout.write(new_word + "\n")
new_word = ""
|
Output:
Smcinrablg wodrs very Bauscee eevn tehy dnoes't
icpamt Bcuesae d'not read lteter raed wrod whole.
