编写函数perfect_number: 首先,我们需要定义一个名为perfect_number的函数,它接受一个参数limit,该参数有一个默认值1000。这个函数将用于寻找并返回在1到limit范围内的所有完美数。 python def perfect_number(limit=1000): # 函数体将在下面编写 遍历从1到limit的所有整数: 在函数内部,我们将使用一个for循环...
# Define a function named 'perfect_number' that checks if a number 'n' is a perfect number def perfect_number(n): # Initialize a variable 'sum' to store the sum of factors of 'n' sum = 0 # Iterate through numbers from 1 to 'n-1' using 'x' as the iterator for x in range(1...

* Python/PHP/Java - 后端,结构和逻辑并重的语言。其实它是最好编写 Unit testing 的语言,因为它只负责一件事情:提供 API 供调用,我们只需要模拟输入,判断程序是否会出现 Error 即可,Django 提供了很好的 Unit testing 框架,可以模拟客户端的提交数据,以检测 Views 和 Controller 能否正常工作,Models 能否对数据库...

Or using the time specifier (ms): nodemon --delay 2500ms server.js The delay figure is number of seconds (or milliseconds, if specified) to delay before restarting. So nodemon will only restart your app the given number of seconds after thelastfile change. ...
