2.3动手试一试

　　2-3将用户的姓名存到一个变量中，并向该用户显示一条消息。如“Hello Eric，would you like to learn some Python today?”

name = 'eric'
print("Hello" +" " + name.title() +" would you like to learn some Python today?" )

　　

Hello Eric would you like to learn some Python today?

　　2-4 调整名字大小写：将一个人名存储到一个变量中，再以小写、大写、首字母大写的方式显示这个人名

name = "yuxin"
print(name.title())
print(name.upper())
print(name.lower())

　　

Yuxin
YUXIN
yuxin

　　2-5名言 将这个名人的姓名和他的名言打印出来 输出应类似于下面这样（包括引号）：

Albert Einstein said, "A person who never made a mistake never tries anything new."

name = 'alber einstein'
print(name.title() + " " + "once said," + "\"" + "A person who never made a mistake never tried anything new.\"")

　　

Alber Einstein once said,"A person who never made a mistake never tried anything new."

　　2-6 存储一个人名， 并在其开头和末尾都包含一些空白字符。务必至少使用字符串组合‘‘\t"和"\n"各一次。打印这个人名，以显示其开头和末尾的空白。然后，分别使用剔除函数lstrip(),rstrip()和strip()对人名进行处理，并将结果打印出来

name = " \n\tyuxin\t  "
print(name.rstrip())
print(name.lstrip())
print(name.strip())
