Question

Using Python 3

Write a program that reads the 4letterwords.txt file and outputs a file called 4letterwords.out that has every word found in 4letterwords.txt but each word on one line. Any leading and trailing blank spaces must be removed in the output file.

Answer 1

Please let me know if anything is required. Please follow the indentation as shown in the code screenshot.

NOTE: I have written two programs , one is to write all words in to a same line of outputfile and other to write each word in a single line. You can use whatever you want.

line=line.rstrip()#to remove trainling spaces
f2.write(line+" ") #writing all the words into a single line after removing leading and trailing spaces
