Day 04 字符串作业

2-1 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?”。

name = "Eric"  #三种打印方式

print("Hello %s, would you like to learn some Python today?" % name)
print("Hello {}, would you like to learn some Python today?".format(name))
print("Hello " + name + "," + " 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 = "eryang"

upper_name = name.upper()
lower_name = name.lower()
title_name = name.title()

print(upper_name, lower_name, title_name)

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('Jason Statham once said, \"Before you get up every day there are two choices,\neither to continue to get down to do your unfinished dreams,\neither pull the quilt complete your unfinished dreams\"')

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_man = "Jason Statham"     
sentence = "Before you get up every day there are two choices,\neither to continue to get down to do your unfinished dreams,\neither pull the quilt complete your unfinished dreams"
# 三种打印出消息的方式
print(famous_man + ' once said,' + '\"' + sentence + '\"')
print("{} once said,{}{}{}".format(famous_man, '"', sentence, '"'))
print("%s once said, %s" % (famous_man, sentence))

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。

person_name = "\teryang\t\n "

lname = person_name.lstrip()
rname = person_name.rstrip()
gname = person_name.strip()

print(person_name, lname, rname + "\n" + gname)
