Python入门的36个例子——04 优雅的字符串

# 004
# 利用三引号(''' or """)可以指示多行字符串
print '''line1
line2
line3'''
# 另外，你还可以在三引号中任意使用单引号和双引号
print ''' "What's up? ," he replied.'''
# 否则，你好使用转义符来实现同样的效果
# 还是使用三引号好，不然就破坏了视觉美了
print ' \"What\'s up? ,\" he replied.'
# 你可以使用raw（r）（原始字符串）来消除转义字符的转义功能
print r' \"What\'s up? ,\" he replied.'
# 单引号和双引号的全等性似乎意味着Python中没有“char”这个概念
# 事实正是如此！
# “char”是为机器服务的（The genesis of the computer revolution was in a machine. The genesis of our programming languages thus tends to look like that machine.）
# 而Python是为程序员服务的
