                 第一种：直接用%d
                 4 x = ‘There are %d types of people‘ % 10  
 5 6#第二种：用%s来将变量转换成字符串 7 8# 定义binary 9 binary = ‘binary‘10# 定义do_not11 do_not = "don‘t"12# 定义y的意思（把变量转换成字符串）13 y = ‘Those who know %s and those who %s.‘ % (binary, do_not)
1415# 输出x16print x
17# 输出y18print y
1920#第三种：用%s和%r来将变量转换成字符串，该变量也适用%s和%r来定义的21# 输出 我说过了x （把变量转换成字符串）22print‘I said: %r.‘ % x
23# 输出 我说过了y （把变量转换成字符串）24print"I also said: ‘%s‘." % y
2526# 定义hilarious27 hilarious = False
28# 用含有格式转换符的字符串定义joke_evaluation29 joke_evaluation = "Isn‘t that joke so funny?! %r"3031# 输出一个含有转换符的变量32print joke_evaluation % hilarious
3334# 定义W和e35 w = ‘This is the left side of ...‘36 e = ‘a string with a right side.‘3738# 输出 w+e39print w+e
