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

We will inevitably use a lot of repetitive tedious work in software development, such as bulk modification of the interface strings in the code, batch download files and re-named by the rules, these work is particularly tiring, especially for me lazy people.

Repetition is one of the most unacceptable things for a good programmer, so we invent tools to automate repetitive work. I used to do this with a Linux shell script, but due to the limitations of shell scripting syntax, some of the complex functions can not be effectively and quickly implemented, and the written code is difficult to maintain, basically belong to one-time code, difficult to reuse. So after slowly beginning to try to use Python to complete some automation scripts, because of the Python language powerful expressiveness and strict writing specifications, these shortcomings are solved!

Recently, we are going to put together some of the daily development of the Python script for the open source, so there is this topic, hoping to help you get rid of the 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 deletes the specified string in a file in a bulk delete directory, and this script can be used to delete the log statements in the code in bulk.
