In this section, we demonstrate how to create a query using a single query operator. To create more complex queries, we can add other query operators after the expressions to generate a query chain. For example, query all the names with the le

In practice, by using Git diff to calculate the number of code changes, there is a need to just count certain types of files (files with special suffix names/extensions), such as: Only the variables for files in the current git repo. java,. xml,. c,. cpp. There are two ways to make git count according to the file suffix name and to count the eligible files in each subdirectory. 1. Use the ' *.java ' and ' *.xml ' directly, if your git version is newer (for example: Git >= 1.7.8 version)

Now connected to an IDC MySQL server, due to network isolation, the need to ssh to a springboard to direct access to MySQL, and I want to use mysqlworkbench such as local clients directly connected to MySQL. The solution is to set up an SSH tunnel with the SSH command, and then Mysqlworkbench connect to the corresponding remote MySQL only by connecting to a local port.

I. A brief introduction to the dictionary The Dictionary (dict) is the only type of mapping in Python. He is composed of key-value pairs enclosed in {}. In Dict, key is unique. When saving, a memory address is calculated based on key. Then save the Key-value in this address. This algorithm is called the hash algorithm, so, remember, in the dict stored in the Key-value key ' must be hash, if you do not understand what is hash, temporarily can remember, can change is not hash, then the hash means
