# end=' ' 的意思是告诉print不要用换行符结束这一行，用户直接输入值定义age变量
print("How odl are you?", end=' ')
age = input()
print("How tall are you?", end=' ')
height = input()
print("How much do you weight?", end=' ')
weight = input()
# 使用了格式化
print(f"So, you're {age} old, {height} tall and {weight} heavy.")
# 还可以这样写
print("他的年龄是{0},体重是{2},身高是{1}".format(age,height,weight))
