2-3 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?”。
name='Eric'
str1='”hello'+' '+name+','+'would you like to learn some Python today?”'
print(str1)
结果显示
“hello Eric,would you like to learn some Python today?”
2-4 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。
name='jack'
print(name)
name1=name.capitalize()
print(name1)
name2=name1.upper()
print(name2)
结果显示
jack
Jack
JACK
2-5 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.”
print('Albert Einstein once said, Politeness more powerful than law.')
结果显示
Albert Einstein once said, Politeness more powerful than law.
2-6 名言2: 重复练习2-5,但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('%s once said:%s'%(famous_person,message))
结果显示
Albert Einstein once said:“A person who never made a mistake never tried anything new.”
2-7 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。
name=('\tjack\n'+'***')
print(name)
name1=name.rstrip()
print(name1)
name2=name.lstrip()
print(name2)
结果显示
jack
***
jack
***
jack
***
