for i in range(1,10):
	for j in range(1,i):
		print(f"{i}*{j}={i*j}")

🃏 三、扑克牌规律实现

1. 使用循环输出四种花色

suits = ["♠", "♥", "♣", "♦"]
for suit in suits:
	print(suit)

2. 在第一个循环中嵌套第二个循环，输出A-K，并以字符串方式拼接第一个循环中的花色

suits = ["♠", "♥", "♣", "♦"]
ranks = ["A", "2", "3", "4", "5", "6", "7", "8", "9", "10", "J", "Q", "K"]

for suit in suits:
	for rank in ranks:
		print(f"{suit}{rank}")

3. 输出大王和小王

print("🃏大王")
print("🃏小王")
