	<li><code>s</code> consists of only English letters and spaces <code>&#39; &#39;</code>.</li>
	<li>There will be at least one word in <code>s</code>.</li>

class Solution:
    def lengthOfLastWord(self, s: str) -> int:
        w=s.strip().split()
        if not w:
            return 0
        return len(w[-1])
