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?”。
name1 ='vinci'
print('Hello %s,would you like to learn some Python today?'%(name1))
#print('Hello '+name1+',would you like to learn some Python today?')
#print可以用逗号将多个内容同时打印,但多个内容用空格隔开
print('Hello ',name1',would you like to learn some Python today?')
结果显示
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。
name1 = 'Vinci da'
print(name1.upper())
print(name1.lower())
print(name1.title())
结果显示
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.”
name1 = 'Tesia'
word = 'Common sense is the collection of prejudices acquired by age eighteen.'
print("%s once said,\"%s\""%(name1,word))
# print('%s once said,"%s"'%(name1,word))另一种方法
结果显示
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='Tesia'
message='Common sense is the collection of prejudices acquired by age eighteen.'
print(famous_person+' once said,'+'\"'+message+'\"')
#print(famous_person+' once said,'+'"'+message+'"') 另一种方法
结果输出
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。
famous_name = '\t\tVinci da\n\n'
print(famous_name)
print(famous_name.lstrip())
print(famous_name.rstrip())
print(famous_name.strip())
结果输出
