Python單引號雙引號三引號的區別

一、單引號與雙引號用於單行，功能上是等價的。

   　二者配合使用，減小使用轉義符。

  例如：　等價的

　　　print "I LOVE 'CHINA'"

　　　print 'I LOVE \'CHINA\''

２、三引號用於多行，內部不使用轉移符，原樣輸出。

　　print ''' I LOVE 'CHINA'   '''（等價）

示例:

days="Mon Tue Wed Thu Fri Sat Sun"
months="Jan\nFeb\nMar\nApr\nMay\nJun\nJul\nAug"

print "Here are the days:",days
print "Here are the months:",months

print """
