使用f-string 填充和填充: 我们可以用小数点后的数字或某个给定的数字或日期时间输入和指定格式,这称为 f-string 填充。 1. 0-padding :在这里,我们通过在 f-string {} 语法中添加{variable : 0N}来应用 0-padding,其中 N 表示总数。位数。

print(string1.ljust(10,"0")) print(string2.ljust(8,"0") Output That’s it! We have compiled multiple methods for padding the Python string with leading zeros. Conclusion To pad the string with leading zeros in Python, the “f-string“, the “format()” method, the “zfill()” meth...
The f-strings have thefprefix and use{}brackets to evaluate values. Format specifiers for types, padding, or aligning are specified after the colon character; for instance:f'{price:.3}', wherepriceis a variable name. Python string formatting ...
为了进一步简化格式化方法,Eric Smith 在2015年提交了 PEP 498 – Literal String Interpolation 提案。 PEP 498 提出了一种新的字符串插值方法,该方法可以更简单便捷的使用 str.format 方法。你只需要在字符串开头加上一个字母 f,形成 f”” 的格式就可以了。
F-strings are the clear winner in terms of readability. However, they don’t allow you to do lazy interpolation. There’s no way to use an f-string to create a reusable string template that you can interpolate later in your code. If you want a universal tool with all the features, th...
