求输入的三个数如何由大到小输出
num = input('请输入数字\n')
num = num.split()
a,b,c = num
a,b,c = int(a),int(b),int(c)
if a > b : a,b = b,a
if a > c : a,c = c,a
if b > c : b,c = c,b
print("输出结果 : %d %d %d" %(a,b,c)) # 也可以使用sort方法进行排序
s = [input(),input(),input()]
s.sort()
print "输出结果: %s" %s

print()
# 另一种方法
c = 0
while c < 9:
c +=1
a = 0
while a < c:
a += 1
print('{} x {} = {}'.format(c,a,a*c),end=" ")
print()
