As you’ll see shortly, you can control the justification and padding of string output with the <width> and .<precision> conversion specifier components. Remove ads The Literal Percent Character (%%) To insert a percent character (%) into the output, you can specify two consecutive percent ch...
用string.format：>>> msg = 'hello world'>>> 'msg: {}'.format(msg)'msg: hello world'有了f-string后，可以简化成如下：>>> msg = 'hello world'>>> f'msg: {msg}''msg: hello world’可以看到，用fstring明显就清晰简化了很多，并且也更加具有可读性。fstring的一般用法如下：可以f或者F开头，...
This is done to keep the original value of the number in case the string was a number. Running this code would give us: 0015 +0015 -0015 format() Theformat()function is the most advanced in the list. This single function can be used for left, right, and even center padding. It is...
