1.个性化消息:
将用户的姓名存到一个变量中，并向该用户显示一条消息。显示的消息应非常简单，如“Hello Eric, would you like to learn some Python today?”
name1 = 'Tom'
print("Hello %s,would you like to learn some Python today" %name1)
输出：
Hello Tom,would you like to learn some Python today
2.调整名字的大小写:
将一个人名存储到一个变量中，再以小写、大写和首字母大写的方式显示这个人名
name2 = 'summer'
print(name2.lower()) #全部小写
print(name2.upper()) #全部大写
print(name2.capitalize()) #首字母大写
输出：
summer
SUMMER
Summer
3.名言:
找一句你钦佩的名人说的名言，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 once said, “A person who never made a mistake never tried anything new.”
str1 = 'Albert Einstein once said,'
str2 = '“A person who never made a mistake never tried anything new.”'
print(str1 + str2)
输出：
Albert Einstein once said,“A person who never made a mistake never tried anything new.”
4.重复练习3
将名人的姓名存储在变量famous_person 中，再创建要显示的消息，并将其存储在变量message 中，然后打印这条消息
famous_person = 'Albert Einstein'
message = '“A person who never made a mistake never tried anything new.”'
print(famous_person + ' once said,' + message)
输出：
Albert Einstein once said,“A person who never made a mistake never tried anything new.”
5.剔除人名中的空白:
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
name3 = '\txiatian \n'
print(name3)
print(name3.strip(),name3.lstrip(),name3.rstrip())
输出：
xiatian
xiatian xiatian
xiatian
