    1. 当一个字符串包含多个相同的变量时,使用如下方法:
      代码:
    str = '%(foo)s is %(foo)s is %(foo)s' %{'foo': 'look at'}
    print str
    str1 = '{0} {0} {1}'.format('look at', 'python')
    print str1
    
    str2 = '{foo} {foo} is {snow}'.format(foo='look at', snow='world')
    print str2
    

    输出:

    look at is look at is look at
    look at look at python
    look at look at is world
