Python中的字符串格式 [英] String formatting in Python
问题描述
我想做一些像 String.Format([{0},{1},{2}],1,2,3)
:
[1,2,3]
如何在Python中执行此操作?
格式化,正在Python 3.0 +中逐步淘汰。假设你使用的是Python 2.6+,下面介绍一个更具前景的格式化系统: library / string.html#formatstringsrel =noreferrer> http://docs.python.org/library/string.html#formatstrings
虽然还有更高级的功能,但是最简单的形式最终看起来非常接近你写的:
>> >格式(1,2,3)
[1,2,3]
I want to do something like String.Format("[{0}, {1}, {2}]", 1, 2, 3)
which returns:
[1, 2, 3]
How do I do this in Python?
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
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]
