Python - 为字符串格式化运算符解压缩列表的简短方法？

Question

不幸的是，*或**运算符的变化似乎不起作用：

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

有一个简单的方法吗？

Answer 1

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。

Answer 2

s = 'The %s are %d, %d, %d, and %d' % tuple(['numbers'] + lstData)

Answer 3

>>> data = range(5)
>>> 'The {0} are {1}, {2}, {3}, {4} and {5}'.format('numbers', *data)
'The numbers are 0, 1, 2, 3 and 4'
