Python中的语句(Statements)、表达式(Expressions)以及函数(Functions)是Python编程的三个基础组成部分,它们之间有着明显的不同。首先,表达式是一个组合了变量、操作符和方法调用等的代码片段,它可以被解释器计算并返回一个值。语句,则是执行特定操作的完整指令,比如赋值语句、条件语句等,不同于表达式,它不返回值。而函...
statement有两个含义：第一个是个很宽泛的概念，即程序设计者写下的“一行代码”（当然也可能是几行）。

So, I'm needing the statement to say something as listed below. I'm fairly new to python and would appreciate any help for code to put into my field calculation. If value in Flood Zone is A,AE, AH, AO, etc then Flood Risk is High. If value in Flood Zone is Whatever, then ...
Removal of the early return statement in validate_task seems intentional; ensure that tasks with no validation issues are still processed correctly downstream. Reason this comment was not posted: Confidence changes required:33%<= threshold50%
