为何一个输出单引号一个双引号结果

hachikoweitong

这段代码的两个print结果中为何一个是单引号一个是双引号？
x = "There are %d types of people." %10
binary = "binary"
do_not = "don't"
y = "Those who know %s and those who %s." %(binary, do_not)
print "I said: %r." %x
print "I also said: %r." %y

do_not有单引号，所以不能再是单引号

1. >>> do_not = "dont"
   
2. >>> y = "Those who know %s and those who %s." %(binary, do_not)
   
3. >>> print "I also said: %r." %y
   
4. I also said: 'Those who know binary and those who dont.'.
