September, Hello!

    The start of the September season has nothing to do with me.    There is no love on campus.    I am not a student, but I want to go back to school again.    I miss the innocence of primary school, the laughter of junior high school, the depression of high school, and the inaction of the University.    I’m working overtime this weekend. I’m typing code. I’m studying hard. I’m getting better and growing up.    Maybe life needs to be busy to get bored, and give yourself enough time to learn, come on!!!

Python grabs the interface and keeps the picture.

Https://blog.csdn.net/xpliruizhi123/article/details/54580850        Recently, it has been found that KETTLE decimation is getting slower and slower, especially when the incremental INSERT / UPDATE is incremental (TRASFORMATION takes 20 incremental decimations of 30 W per day from a 400 W table)Hour!!!! The read rate is 5/s…), which was discovered after my KETTLE tool was upgraded from 3.2 to 7.0 (slower than it used to be, it’s just acceptable, it...

Python—11 module

In the process of computer program development, as more and more program code is written, the code in a file will become longer and longer, more and more difficult to maintain. In order to write maintainable code, we grouped many functions into separate files, so that each file contained relatively little code, and many programming languages used this method of organizing code. In Python, a.Py file is called a module (Module).). What are the advantages of using modules? The biggest benefit is greatly improving the maintainability of the code. Second, writing code does not need to start from s...
