Write a python function that simplifies the given text. The function takes a string as input and converts the string to all lowercase, removes all common punctuation except commas and returns the new string. I need this to be answered as soon as possible please. I'll give thumbs up and good comments.

python help... Write a function justVowels() that takes a string as a parameter and returns a new string that contains all the vowels found in the parameter string. The vowels in the returned string should appear in the same order as they did in the parameter string. A vowel is one of a, e, i, o, or u. both the upper- and lower-case vowels should be included. The characters in the returned string should have the same capitalization as they did in the parameter string. If the function is given a string without any vowels or an empty string, it should return the empty string. Use the if-else condition with iterate loop pattern. Don’t forget to include the docstring and comments.    How it should run... >>> justVowels('Did you include your collaboration statement') 'iouiueouoaoaioaee' >>> justVowels('If you did not include your collaboration statement no points') 'Iouioiueouoaoaioaeeooi' >>> justVowels('1,2,3,4,...') '' >>> justVowels('') ''

for python programming make a program,  that has a function that takes in a string argument and prints a sentence indicating the shortest word in that string. If there is more than one word print only the first.  Your print statement should read:               “The shortest word is x”               Where x = the shortest word.  The word should be all uppercase.

Using import sys : Create a python program, palindrome.py, that has a function that takes one stringargument and prints a sentence indicating if the text is a palindrome. Thefunction should consider only the alphanumeric characters in the string, and notdepend on capitalization, punctuation, or whitespace.If your string is a palindrome it should print:It's a palindrome!If it is not a palindrome, it should print:It's not a palindrome!
