Python中的过滤器add、cut、date、join、length、lower、upper、random、safe、slice、truncatechars、truncatechars_html 在DTL模板中,不支持函数的调用形式“()”,因此不能给函数传递参数,这将有很大的局限性,而过滤器其实就是一个函数,可以对需要处理的参数进行处理,并且最多可以接收两个参数。
publicString addStrings(String num1, String num2) { StringBuilder sb =newStringBuilder(); intcarry =0; for(inti = num1.length() -1, j = num2.length() -1; i >=0|| j >=0|| carry ==1; i--, j--){ intx = i <0?0: num1.charAt(i) -'0'; ...

In Python, it’s impossible to include backslashes in curly braces{}of f-strings. Doing so will result into aSyntaxError: >>> f'{\}' SyntaxError: f-string expression part cannot include a backslash This behaviour aligns perfectly withPEP-0498which is about Literal String Interpolation: ...
