Design a Python function to eradicate all vowels from a given string.
Given a string, the task is to create a function that removes all vowels - 'a', 'e', 'i', 'o' & 'u' (along with their capitalized forms) - from the string. Vowels are characters that represent sounds made with an open vocal tract. ### Parameters - `txt` (3-100 characters long string): The input string from which vowels are to be removed. ### Return Value - The function returns a string, identical to `txt`, but without any vowel characters. ### Examples ```python remove_vowels("I have never seen a thin person drinking Diet Coke.") # Returns: " hv nvr sn thn prsn drnkng Dt Ck." remove_vowels("We're gonna build a wall!") # Returns: "W'r gnn bld wll!" remove_vowels("Happy Thanksgiving to all--even the haters and losers!") # Returns: "Hppy Thnksgvng t ll--vn th htrs nd lsrs!" ```
