This is a new string."。 4. 使用字符串格式化方式创建字符串 字符串格式化是一种更加灵活的方式来创建字符串。可以使用format()方法将变量的值插入到字符串中。以下是一个示例代码: name="Alice"age=25formatted_text="My name is {} and I'm {} years old.".format(name,age) 1. 2. 3. 上述代码...
Then, it applies the specifier to the value to return a formatted value. The format specifier must follow the rules of the string formatting mini-language.Just like the .format() method, f-strings also support the string formatting mini-language. So, you can use format specifiers in your f...
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...

Formatted String Literals (f-strings)¶ This method is known as Literal String Interpolation or f-strings. It makes the string interpolation simpler by embedding the Python expressions inside string constants. It works by prefixing the string either withforF. The string can be formatted in the...
