I. INTRODUCTION TO IF-THEN STRUCTURE If-then结构是编程中最基本的决策工具之一。在各种编程环境中,这种结构提供了一种方式,允许程序根据不同的输入或状态进行响应。在实践中,这通常涉及检查一系列条件,然后根据这些条件是否满足来执行相应的代码块。 II. THE CONDITIONAL STATEMENT 在任何支持if-then结构的编程语言...
Else, there should be ‘no discount‘ To apply IF and ELSE inPython, you can utilize the following generic structure: Copy if condition_1: perform an action if condition_1 is met else: perform an action if condition_1 is not met And for our example, let’s say that the person’s ag...
