built-in type conversion functions like int (), type (), list () are all factory functions, which means they look like functions, essentially classes, and when they are called, they actually generate an instance of that type, like a factory-generated cargo.8.

Func is None, Func behaves as an identity function, returning a list of n tuples containing the set of elements in each sequence. Reduce (func, seq[, Init]) applies the two-tuple function to the elements of the SEQ sequence, each time carrying a pair (previous results and the next sequence element), successively adding the existing result and the rain to the value on the resulting subsequent result, and finally reducing our sequence to a single return value If the initial value init is given, t

, and then gives the corresponding properties. Please do the same experiment on the types module. Make a note of the types you are familiar with, including your knowledge of these types, and then note the types that you are not familiar with. In the process of learning Python, you will gradually become "familiar" with the "unfamiliar" type.Edit by VheavensEdit by Vheavens4–8. Lists and tuples. What is the same point for lists and tuples?

First, what is a Python objectIn Python, a value of any type constructed is an object. For example, a value of an integer type, a string, a list, and so on, can be considered as objects.All objects are divided into three parts:(1) identity. Each object has an ID that identifies itself. Available built-in function ID () view(2) type. Available type () view(3) value. Objects are used to hold data, and the mos
