Automatically add friends to simulate locations and friends to simulate
Friends around the world want to customize their locations for purchase, and can search for nearby users to automatically say hello.
In fact, the principle is relatively simple, mainly through the map SDK (Baidu, or AMAP) to obtain the corresponding location latitude and longitude, and then set to the current location (virtual locatio

Python methods and performance comparisons for obtaining letters at corresponding locations in the alphabet
In some cases, we are asked to find out the alphabet in the order of the alphabet, a = 1,b = 2, C = 3, and so on, such as the topic https://projecteuler.net/problem=42 one step to solve the problem is to convert the letters to the corresponding order in the alphabet.
The easiest way to get the alphabet to correspond to the alphabet is to:

Based on thinkphp, it can be used to determine geographical locations based on users' ip addresses and provide corresponding weather information.
We all know that many websites provide weather forecasts for users. Sometimes, even if users do not enter any geographical location information related to themselves, the same website can also determine the geographic location and display the weather information. We may think of using ip addresses to determi
