在Python中,我们可以使用内置的round()函数来截断浮点数后面的小数。不进行舍入的方法是将小数部分与整数部分相加后取整数部分,可以使用math模块中的floor()函数或者int()函数来实现...

To round every value down to the nearest integer, use np.floor(): Python >>> np.floor(data) array([[-1., -3., -1., 0.], [ 0., 0., -1., 0.], [-1., -1., 0., -1.]]) You can also truncate each value to its integer component with np.trunc(): Python >>>...
round 默认对数字进行四舍五入,也可以用参数进行控制 int 把值转换成整型 除了上述特性,Jinja2 还有其他一些有用的功能,下面介绍其中几个: 安全过滤器 在模板中渲染用户提供的数据时,安全性是一个非常重要的问题。Jinja2 提供了一个安全过滤器,可以帮助我们过滤掉一些危险的 HTML 标签和属性,以防止 XSS 攻击等安全...
