Expression 为true或false 勾选interpret condition as variable expression ,表达式可以直接输入true,请求A会执行,输入false,请求B不会执行 运行后只有请求A会执行 jexl3 或groovy 函数 勾选interpret condition as variable expression ,表达式可以通过__jexl3或__groovy函数转成 true 或 false 结果 先定义一个变量use...

与之前带for嵌套的语法不同,这个例子中,实际使用的是最基本的[expression for x in L]语法,只有一个for语句。 复杂的地方在于前面的变量表达式expression不再是简单的变量运算,而是一个列表推导式,在这个例子中就是[y for y in range(x, x+3)]。
其中，如果condition为True，则result等于value1；否则result等于value2。with语句 with语句是Python中一种非常方便的资源管理方式。它可以自动管理资源的打开和关闭操作，比如文件、网络连接、数据库连接等。使用with语句可以避免忘记关闭资源而导致的内存泄漏等问题。with语句的基本格式如下：pythonwith expression as ...
