格式化字符串

一、格式化字符串：【%和format的使用方法】

1. % 常用格式：
tpl = "i am %s age %d" % ("alex", 18)
tpl = "i am %(name)s age %(age)d" % {"name": "alex", "age": 18}
tpl = "i am %.2f %%" % {"pp": 123.425556, }

2.Format方式
tpl = "i am {}, age {}, {}".format("seven", 18, 'alex')
tpl = "i am {}, age {}, {}".format(*["seven", 18, 'alex'])
tpl = "i am {0}, age {1}, really {0}".format("seven", 18)
tpl = "i am {0}, age {1}, really {0}".format(*["seven", 18])
tpl = "i am {name}, age {age}, really {name}".format(name="seven", age=18)
tpl = "i am {name}, age {age}, really {name}".format(**{"name": "seven", "age": 18})
