F-strings also support format specifiers that control numerical precision, alignment, and padding. Format specifiers are added after a colon (:) inside the curly brackets. For instance,f'{price:.3f}'ensures that the floating-point number stored inpriceis rounded to three decimal places: price =...
F-strings provide a modern and intuitive way to format strings in Python by using a simple prefix and expression syntax. Let's start with the fundamentals of creating f-strings. Creating an f-String To create an f-string, simply add the letter 'f' or 'F' before your string literal. Bo...

在f-string方法中,各种Python表达式都可以出现在{}里,于是这就解决了前面提到的第二个缺点。我们现在可以用相当简洁的写法对需要填充到字符串里面的值做出微调。C风格的写法与采用str.format方法的写法可能会让表达式变得很长,但如果改用f-string,或许一行就能写完。
value = 0.5 # 50% in decimal form percentage = f"{value:.2f}%" # format the value to a string with 2 decimal places and append a "%" sign print(percentage) # output: 50.00% 在Python中，我们可以使用多种方法来输出百分比。最常用的方法是使用print()函数和格式化字符串。从Python 3.6...
