Need help removing the remaining whitespace in a string in Python-CodePudding

I need help with a school assignment trying to remove all the whitespace from the non-newline lines in my output in Python 3. I want to do this so I can convert my string into a list. I can use RegEx but not xml in my code. Currently when I run my program it outputs this:

Belgian Waffles
    $5.95
    Two of our famous Belgian Waffles with plenty of real maple syrup
    650


    Strawberry Belgian Waffles
    $7.95
    Light Belgian waffles covered with strawberries and whipped cream
    900


    Berry-Berry Belgian Waffles
    $8.95
    Light Belgian waffles covered with an assortment of fresh berries and whipped cream
    900


    French Toast
    $4.50
    Thick slices made from our homemade sourdough bread
    600


    Homestyle Breakfast
    $6.95
    Two eggs, bacon or sausage, toast, and our ever-popular hash browns
    950
    (end of output)

The result I'm trying to get is this:

Belgian Waffles
$5.95
Two of our famous Belgian Waffles with plenty of real maple syrup
650


Strawberry Belgian Waffles
$7.95
Light Belgian waffles covered with strawberries and whipped cream
900


Berry-Berry Belgian Waffles
$8.95
Light Belgian waffles covered with an assortment of fresh berries and whipped cream
900


French Toast
$4.50
Thick slices made from our homemade sourdough bread
600


Homestyle Breakfast
$6.95
Two eggs, bacon or sausage, toast, and our ever-popular hash browns
950
(end of output)

This is the current code that I have right now:

import os
import re


def get_filename():
    print("Enter the name of the file: ")
    filename = input()
    return filename


def read_file(filename):
    if os.path.exists(filename):
        with open(filename, "r") as file:
            full_text = file.read()
            return full_text
    else:
        print("This file does not exist")


def get_tags(full_text):
    tags = re.findall('<.*?>', full_text)
    for tag in tags:
        full_text = full_text.replace(tag, '')
    return tags


def get_text(text):
    tags = re.findall('<.*?>', text)
    for tag in tags:
        text = text.replace(tag, '')
        text = text.strip()
    return text


def display_output(text):
    print(text)


def main():
    filename = get_filename()
    full_text = read_file(filename)

    tags = get_tags(full_text)
    text = get_text(full_text)

    display_output(text)


main()

I want it to output without the whitespace so that I can convert this string to a list without those left aligned whitespace being counted as elements. Any help or suggestions would be appreciated.

CodePudding user response：

Split the page by the newline character \n and loop through the list.

page = ...

new_page = ''
for line in page.split('\n'):
    new_page  = line.lstrip().rstrip()

Adding the lines to a new string variable.

Good day.
