else: 执行语句…… 1. 2. 3. 4. 前面也提到过,Python 语言有着严格的缩进要求,因此这里也需要注意缩进,也不要少写了冒号:。 if 语句的判断条件可以用>(大于)、<(小于)、==(等于)、>=(大于等于)、<=(小于等于)来表示其关系。 例如: # -*-coding:utf-8-*- ...
如果"condition_2" 为 True 将执行 "statement_block_2" 块语句 如果"condition_2" 为False,将执行"statement_block_3"块语句 Python 中用 elif 代替了 else if,所以if语句的关键字为:if – elif – else。 注意: 每个条件后面要使用冒号 :,表示接下来是满足条件后要执行的语句块。
