If you need a tool for doing lazy string interpolation, then the .format() method is the way to go. In contrast, the modulo operator (%) is an old-fashioned tool not commonly used in modern Python. You could say
print(templated.interpolations[0].value)# 输出:World print("".join( itemifisinstance(item, str)elsestr(item.value) foritemintemplated ))# 输出:Hello World! 如上所述,t-string 与 f-string 不同的是,它不会立即得到普通字符...
String interpolation is a process substituting values of variables into placeholders in a string. For instance, if you have a template for saying hello to a person like "Hello {Name of person}, nice to meet you!", you would like to replace the placeholder for name of person with an actua...
一说起字符串格式化,我们脑海里最先出现的必然是%和format,但是在python3.6之后,又更新了一种更快更便捷的方法,那就是f-string!它是由PEP 498 所带来的全新的一种方法,全称是“Literal String Interpolation”。 百科的资料,小水一下!接下来给大家分享一下,它的使用方法及注意事项。 f-string的使用 首先要确保...

在Python中,print(f’') 是一种格式化字符串的便捷方式,称为 f-string(格式化字符串字面量)。f-string 是在 Python 3.6 中引入的,它提供了一种非常直观和高效的方法来嵌入表达式到字符串字面量中。 基本语法 f-string 的基本语法非常简单,只需在字符串前加上一个小写的 f 或大写的 F,然后在字符串内部...
This PEP proposed to add a new string formatting mechanism: Literal String Interpolation. In this PEP, such strings will be referred to as “f-strings”, taken from the leading character used to denote such strings, and standing for “formatted strings”. ...
