Solution

def main():
	text = input("Enter string: ")

	count = frequency(text)
	is_pangram = all(value > 0 for value in count)

	print("Pangram" if is_pangram else "Not Pangram")

	# Print the missing letters
	if not is_pangram:
		print("Missing Letters: ", end="")
		for i, value in enumerate(count):
			if value == 0:
				print(chr(ord("a") + i), end="")
		print()


def frequency(text: str):
	count = [0] * 26
	for c in text.lower():
		if "a" <= c <= "z":
			count[ord(c) - ord("a")] += 1
	return count
