More concise solution

I think I have an even better solution since we don't need to explicitly check if each character is an alphabet or not, numerics and special characters are automatically excluded:

def checkIfPangram(self, sentence: str) -> bool:
        charSet = set("abcdefghijklmnopqrstuvwxyz")
        sentence = sentence.lower()
        for char in sentence:
            charSet.discard(char)
        if len(charSet) == 0:
            return True
        return False

Post has typos, meant the following:

def checkIfPangram(self, sentence: str) -> bool:
        charSet = set("abcdefghijklmnopqrstuvwxyz")
        sentence = sentence.lower()
        for char in sentence:
            charSet.discard(char)
            if len(...
