为了大家能够对人工智能常用的 Python 库有一个初步的了解,以选择能够满足自己需求的库进行学习,对目前较为常见的人工智能库进行简要全面的介绍。 1、Numpy NumPy(Numerical Python)是Python的一个扩展程序库,支持大量的维度数组与矩阵运算,此外也针对数组运算提供大...
# You can basically put any Python statement inside the braces and it will be output in the string. f" is characters long." # => "Reiko is 5 characters long." 最后是None的判断,在Python当中None也是一个对象,所有为None的变量都会指向这个对象。根据我们前面所说的,既然所有的None都指向同一个地...
Because this will define the variable inside the function's scope. It will no longer go to the surrounding (global) scope to look up the variables value but will create a local variable that stores the value of x at that point in time.funcs = [] for x in range(7): def some_func(...
The frame is fit inside the root window. The next line creates a label widget holding a static text string. The grid() method is used to specify the relative layout (position) of the label within its containing frame widget, similar to how tables in HTML work. A button widget is then ...
