The most common approach to check if a number is even or odd in Python is using themodulo operator (%). The modulo operator returns the remainder after division. An even number is evenly divisible by 2 with no remainder, while an odd number leaves a remainder of 1 when divided by 2. ...
ifis_divisible(6,2) ==True:print('divisible') divisible 但是比较是没有必要的。 6.6. 带返回值的递归 现在我们可以编写具有返回值的函数,我们也可以编写具有返回值的递归函数,有了这个能力,我们已经跨越了一个重要的门槛——我们现在拥有的 Python 子集是图灵完备的,这意味着我们可以执行任何可以通过算法描述的...
在这段代码中,使用if语句来判断上述条件,如果同时为真,则显示相应的消息。 类图表示 这段代码的逻辑可以用类图表示,尽管我们并没有使用类,但可以简化地将其表示为: NumberChecker+ number: int+ is_divisible_by_3: bool+ ends_with_3: bool+check_conditions() ...
用户可以在运行之前检查 shell 脚本,甚至可以使用git checkout锁定特定的修订版本。 遗憾的是,pyenv 不能在 Windows 上运行。 安装pyenv 后,将其与运行的 shell 集成在一起是很有用的。我们通过向 shell 初始化文件(例如,.bash_profile)添加以下内容来实现这一点: ...
Check out the following update of adding.py:Python 1def add(a, b): 2 result = a + b 3 return result 4 5print(add(2, 2)) Now, when you run adding.py, you’ll see the number 4 on your screen. So, if you’re working in an interactive session, then Python will show the ...
