书中python2.X的代码：

print “How old are you?”,

age = raw_input() #输入38

实现的效果

How old are you? 38 #38紧跟着第一行

书上说在每行print后面加了个逗号（，），print就不会输出换行符而结束这一行跑到下一行去了。

这个逗号不换行的方法在python3中如何实现？？

以下是用python3.X写的ex11：

print(“How od are you?”)

age = input()

print(“How tall are you?”)

height = input()

print(“How much do you weigh?”)

weight = input()

print(“So, you’re {0} old, {1} tall and {2} heavy.”.format(age, height, weight))

希望的效果

How old are you? 38

实际效果

How old are you?

38

1print("How old are you?" end="")

python3中print()的原型是

1print(value, ..., sep=' ', end='\n', file=sys.stdout, flush=False)

默认输出“\n”，修改掉end的值，让它不输出就可以了

1age = input("How old are you?")
