A collection is an unordered, non-repeating combination of data, and its main functions are as follows: Go to the weight, turn a list into a set, and then automatically go heavy. Relationship test, test the intersection of two sets of

The representation of a string inside Python is a Unicode encoding (8-bit string), so it is often necessary to use Unicode as an intermediate encoding for encoding conversions, that is, decoding the other encoded strings (decode) into Unicode first.

Security Code: Indifferent ChildeFunctions are the basic program structure that Python provides to maximize the reuse and minimization of code redundancy for code.Functions are a design tool that allows programmers to break down complex systems into

First, use the built-in method and decorator method to get the class name, function nameThe case for getting the name of a function in Python is internal, external, well-fetched from the outside, using the object pointing to the function, and then

Cookies are used for server implementation sessions, user login and related functions for state management. To install the Cookie,http server on the user's browser, add an HTTP header that resembles the following to the HTTP

5.1 Number types The numbers provide scalar storage and direct access. It is a non-changeable type, meaning that the value of the change number generates a new object. Of course, this process is transparent to both the programmer and the user, and

Import Module The import declaration is often used in Python to use objects defined in other modules (that is, other. py files). 1) Use __name__ When we write a Python library module, we often run some test statements. We do not need to run these

Python string manipulation real-way collection, including almost all common python string operations, such as string substitution, deletion, interception, copying, connection, comparison, search, segmentation, etc., the need for friends can refer to

The Cookielib library in Python (Http.cookiejar in Python3) provides client support for storing and managing cookies. The main function of the module is to provide objects that can store cookies. Use this module to capture cookies and resend them
