1. tab键可自动从code依次切换到每个pass进行输入,反向操作(回到上一个pass)快捷键是shift+tab 2. pass叫空语句/占位语句,这样代码不会报错,以后可以填上。 3.同一个代码块的一个代码执行,其他代码也会执行,因为是同级代码 不推荐代码嵌套太多级别,会影响阅读感。可以使用函数代替。 --- Elif的用法 elif expr...
The only difference is that you’re using cls instead of func as the parameter name to indicate that it’s meant to be a class decorator. Check it out in practice: Python >>> from decorators import singleton >>> @singleton ... class TheOne: ... pass ... >>> first_one = ...
When you pass a reference-type parameter by value,it is possible to change the data belonging to the referenced object, such as the value of a class member. However,you cannot change the value of the reference itself; for example, you cannot use the same reference to allocate memory for a...

print(dir(list)) 结果: 10.Python 的注释 同时,Python 提供了另外一种让局部程序不被执行的方式,你可以在你希望不被执行的代码块前后两行分别加上 ’’’ 这样的三个单引号。有的地方会称这种方式为多行注释,但是我们并不建议用于添加注释内容时使用,而建议你仅在需要让部分代码暂时不被执行时临时使用这个...

In the example above, I generated a new string based on the input values of two already-created variables by using thecurly brackets placeholderto show where the variables should be written. Then, I passed the variables as a parameter to the format method. ...

layer.weight = torch.nn.Parameter(tensor) 提取模型中的某一层 modules()会返回模型中所有模块的迭代器,它能够访问到最内层,比如self.layer1.conv1这个模块,还有一个与它们相对应的是name_children()属性以及named_modules(),这两个不仅会返回模块的迭代器,还会返回网络层的名字。
