Question: Write a Python list comprehension to put all the letter x appeared in a string in to a list where each letter x is one

Write a Python list comprehension to put all the letter x appeared in a string in to a list where each letter x is one item of the list. For example, if we have a string of 'fox is jumping over another fox that turns out to be a lynx. Or is that an oblex or oryx?', then we should get this list: ['x', 'x', 'x', 'x', 'x'].
