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?”。

#################
# 2-3 个性化消息#
#################
name = 'Eric'
msg = 'Hello %s,would you like to learn some Python today?' % (name)
print(msg)

Output:
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。

#####################
# 2-4 调整名字大小写#
#####################
name = ['ALICE', 'Bob','crisp']
# 小写显示
name1 = name[0].lower()
print(name1)
# 大写显示
name2 = name[1].upper()
print(name2)
# 首字母大写
name3 = name[2].capitalize()
print(name3)

Output:
alice
BOB
Crisp

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.”

###########
# 2-5 名言#
###########
print('Hemingway once said, "A man can destroyed but not defeated ."')

Output:
Hemingway once said, "A man can destroyed but not defeated ."

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。

############
# 2-6 名言2#
############
famous_person = 'Hemingway'
motto = 'A man can destroyed but not defeated .'
message = '%s once said, \"%s\"' % (famous_person, motto)
print(message)

Output:
Hemingway once said, "A man can destroyed but not defeated ."

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。

################
# 2-7 剔除空白 #
################
another_name = '  \tAlbert \nEinstein  '
print(another_name)
var1 = another_name.lstrip()
var2 = another_name.rstrip()
var3 = another_name.strip()
print('剔除开头空白%s:',var1,'\n剔除结尾空白%s:', var2, '\n剔除两端空白%s:', var3)

Output:
    Albert 
Einstein  
剔除开头空白%s: Albert 
Einstein   
剔除结尾空白%s:       Albert 
Einstein 
剔除两端空白%s: Albert 
Einstein
