小白自学python第三天，while循环和for循环分别打印乘法口诀表，请指教！！！
# while循环输出乘法口诀表
a = 0
b = 0
while b < 9:
b = b + 1
a = 1
print("%d*%d=%d" % (a, b, a * b), end="t")
while a < b:
a = a + 1
print("%d*%d=%d" % (a, b, a * b), end="t")
if a == b:
print("")
# for循环输出乘法口诀表
a = []
b = []
for a in range(10):
for b in range(a):
b = b + 1
if a == b:
print("%d*%d=%d" % (a, b, a * b), end="n")
else:
print("%d*%d=%d" % (a, b, a * b), end="t")
b = b + 1
