What is int in python

Students who learn python may have this question, why does the statement int(10) exist in python? Since a=10 and a=int(10) have the same effect, then There is no need to exist int(10), so let us take a look at the following picture

As you can see from the picture, we write a=10 in the code , in fact, the computer still has to call the construction method of int in the end, that is to say, a=10 will eventually become a=int(10) in the computer. If you don’t understand, then let’s take a look at the internal constructor prototype of int def init( self, x, base): There are three parameters in it. The first parameter self: refers to the current object. = decimal, for example: int('1010001',2) this code is parsed as: x=1010001, base=2

The final code will be converted into 10 form and output.
