Convert an integer number to a binary string prefixed with "0b". The result is a valid Python expression. If x is not a Python int object, it has to define an __index__() method that returns an integer. (二).大意 将一个整形数字转换成以"0b"开头的二进制字符串,结果是一个有效的Py...
英文:We looked at a few examples of built-in functions in Python, but being able to define your own functions is incredibly powerful. We start a function definition with the def keyword, followed by the name we want to give our function. After the name, we have the parameters, also call...
To create a decorator, you just need to define a callable (a function, method, or class) that accepts a function object as an argument, processes it, and return another function object with added behavior. Once you have your decorator function in place, you can apply it to any callable....
We must have a nested function (function inside a function). The nested function must refer to a value defined in the enclosing function. The enclosing function must return the nested function.Python Decorators make an extensive use of closures as well....

There is a special function named __init__() that gets called whenever we create a new instance of a class. It exists by default, even though we don't see it. However, we can define our own __init__() function inside the class, overwriting the default version. 注意三,在_ _init_...
