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.”

2-7 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。
答案：

name = 'Trump'
name1 = '\t' + name
name2 = name + '\n'
name3 = '\t' + name + '\n'
name4 = name.ljust(8,)
name5 = name.rjust(8,)
name6 = name.center(8,)
print(name)
print(name1)
print(name2)
print(name3)
print(name4)
print(name5)
print(name6)
print('------------------------')
print(name1.lstrip())
print(name2.rstrip())
print(name3.strip())
print(name4.rstrip())
print(name5.lstrip())
print(name6.strip())

运行结果：
