In these simple cases, there is no need to create extra-large variables to store the data, but rather print one line at a time onto the screen. Using this method will save computer resources while reading files.<source lang="python"><br><br>:#To demonstrate, issue the following code sequence:<source lang="python">

Though (if desired ) you can always strip the new-line characters from any lines. The strip() function will remove all leading and trailing whitespacewhite-space, which may help in processing some lines or data.<br><br>:#To demonstrate, issue the following code sequence:<source lang="python">
