The bulk deletion of Brother Tao's Python toolbox with a specified string line

In software development, We inevitably use a lot of repetitive tedious work, such as the bulk of the code to change the interface strings. Download files in bulk and name them again by Rule. These jobs are particularly tiring, especially for lazy people like Me.

For an excellent program ape, repetition is one of the most unacceptable things, so we have to invent tools to make our work Self-active. I used to use Linux shell scripts to complete these things, but because of the limitations of Shell scripting Syntax. Some complex functions can not be effectively implemented at high speed, and the written code is difficult to maintain, basically belongs to one-time code, very difficult to reuse. So slowly start trying to use Python to complete some of your own proactive scripting. Because of the strong expressiveness and strict writing standards of the Python language, these shortcomings have been overcome!

In the near future, some of the Python scripts used in the daily research and development process have been gradually compiled to open source. So there is this topic, hope can help you get rid of those tedious work.

The code is implemented in the most pythonic way, the tool code is constantly updated, the project git address https://github.com/offbye/TaoPyTools, Remember to the star AH

today, we will analyze a script that contains the rows of a specified string in a file with the specified extension in a bulk delete folder. This script can be used to delete the log statements in the code in BULK.
