Python中的字符串格式化
问题描述
我想做类似 String.Format("[{0}, {1}, {2}]", 1, 2, 3) 的操作，它会返回:
I want to do something like String.Format("[{0}, {1}, {2}]", 1, 2, 3) which returns:
[1, 2, 3]
如何在 Python 中做到这一点?

解决方案
前面的答案使用了 % 格式，在 Python 3.0+ 中正在逐步淘汰.假设您使用的是 Python 2.6+，这里描述了一个更加面向未来的格式化系统:
The previous answers have used % formatting, which is being phased out in Python 3.0+. Assuming you're using Python 2.6+, a more future-proof formatting system is described here:
http://docs.python.org/library/string.html#formatstrings
虽然还有更高级的功能，但最简单的形式最终看起来非常接近您编写的内容:
Although there are more advanced features as well, the simplest form ends up looking very close to what you wrote:
>>> "[{0}, {1}, {2}]".format(1, 2, 3)
[1, 2, 3]
