Today, the editor brings the Getting Started with Python，welcome to visit!一、if语句 if语句表如果，如果满足某某条件，则执行后面得代码。格式为“ if 条件: ”。需要注意的是，满足条件后执行的代码是if语句下面缩进的代码，没有缩进的代码不在if语句的体系内，无论满不满足都会执行。if statement table I...
缩短Python if-statement语法是通过使用三元表达式和逻辑运算符来实现的。在传统的if-else语句中,可以使用条件判断来执行不同的代码块。而通过使用三元表达式,可以在一行代码中实现相同的功能,从而减少了代码量并提高了可读性。 三元表达式的语法如下: 代码语言:txt ...

我的代码旨在根据石头剪刀规则更新胜、平和败,但没有。 我很困惑,因为打印CLASS会得到输出“s”,但将CLASS与“s”进行比较会返回False。有些代码被省略了,省略的代码没有提及胜利、损失、平局、CLASS或class_name Code: data = np.ndarray(shape=(1, 224, 224, 3), dtype=np.float32) ...
