By adding the letter f before the string, we can use curly braces {} to enclose variables or expressions, which will be replaced with their corresponding values.<\/p>\n<p>You can also use simple expressions in curly braces, such as arithmetic operations, function calls, etc. Below is an example of performing simple calculations using the f-string.<\/p>\n<pre class=\"post-pre\"><code>num1 = <span class=\"hljs-number\">10<\/span>\r\nnum2 = <span class=\"hljs-number\">5<\/span>\r\n\r\n<span class=\"hljs-built_in\">print<\/span>(<span class=\"hljs-string\">f\"\u4e24\u4e2a\u6570\u7684\u548c\u4e3a<span class=\"hljs-subst\">{num1 + num2}<\/span>\uff0c\u5dee\u4e3a<span class=\"hljs-subst\">{num1 - num2}<\/span>\u3002\"<\/span>)\r\n<\/code><\/pre>\n<p>The output is:<\/p>\n<pre class=\"post-pre\"><code>\u4e24\u4e2a\u6570\u7684\u548c\u4e3a15\uff0c\u5dee\u4e3a5\u3002\r\n<\/code><\/pre>\n<p>It&#8217;s important to note that f-strings are only available in Python 3.6 and above.
