Python - 为字符串格式化运算符解包列表的简短方法?

2022-01-20 00:00:00 python string tuples formatting

问题描述

不幸的是，* 或 ** 运算符的变体似乎不起作用:

Variations of the * or ** operators don't seem to work, unfortunately:

lstData = [1,2,3,4] str = 'The %s are %d, %d, %d, and %d' % ('numbers', *lstData)

有什么简单的方法吗?

解决方案

使用格式:

str = 'The {} are {}, {}, {}, and {}'.format('numbers', *lstData)

有关可能的格式(浮点数、小数点、转换......)的更多详细信息，请参阅文档.

see the docs for more details about possible formatting (floats, decimal points, conversion, ..).
