Python practical Note (16) functional programming--partial function

Assuming that you want to convert a large number of binary strings, each time it is very troublesome to pass in, int(x, base=2) so, we think, can define a int2() function, the default is base=2 passed in:def int2(x, base=2): return int(x, base)In this way, it is very convenient for us to convert the binary:>>> int2(‘1000000‘)64>>> int2(‘1010101‘)85functools.partialis to help us create a biased function, without our own definition int2() , you can create a new function directly using the followin

Looking at our adorner function- decorator, the function's incoming parameter is func (decorated function), and the return parameter is an inner function. The inner layer function here-wrapper, in fact, is equivalent to the closure function, which plays the role of decorating a given function, the wrapper parameter is *args, **kwargs. The arguments represented by *args are passed in as a list, and the parameters represented by **kw
