新建两个变量，name为xiaoming，gender为boy 3.拼装一个字符串message，内容为his name is xiaoming, his gender is boy 4.把message变成大写形式，然后print输

出来。

可以回答这个问题。代码如下：

name = "xiaoming"
gender = "boy"
message = "his name is " + name + ", his gender is " + gender
print(message.upper())

输出结果为：

HIS NAME IS XIAOMING, HIS GENDER IS BOY
