   The PHP cron expression parser can parse a CRON expression, determine if it is due to run, calculate the next run date of the expression, and calculate the previous run date of the expression. You can calculate dates far into the future or past by…

#事故现场: 对某个对象做空值检测的时候,结合三元运算符给某变量赋值的时候,R#提示:"Simplify conditional ternary expression" : R#建议对该种写法进行简写优化: #解决方案: 我们可以按住 Alt+Enter ,接受R#的建议,则代码优化如下: bool isFuzzySearch = context.Request["IsFuzzySearch"] != null && bool.Parse(conte…

Python中的三目运算其实就是if...else...的语法糖 # 三目运算符:用于简化 if...else...的语法结构# -- 1) 只能解决if...else...结构,其他if分支结构都不管# -- 2)一个分支提供一个结果: 如果一个分支提供了多个结果, 将多个结果通过元组返回 a = int(input('a: ')) b = int(input('b: ')) res = a if a > b else b print(res) 输入: 10 20 输出: 20…
