First, IntroductionAs for regular expressions, I have already made a detailed introduction in the previous (Data Science Learning Codex 31), which summarizes the common functions of the self-contained module re in Python.As a module supported by Python for regular expression related functions, re provides a series of methods to complete the processing of almost all types of textual information, as described

This is a paper I have spent a month in my postgraduate studies. It takes only a month to design and write a paper. It can be more than just a few minutes to publish, add, modify, and wait for the paper to be published, I remember writing started in November 2010. I wrote it in December 2010. I made a draft at the end of 2010. I changed it several times in early 2011 and finally published it in May. In November 2010, my tutor said that there were many topics that could be studied on wireless se
The first example we look at in the drafting process, we need a formula: $p ={12\over q}$, then we observe the effect. And then another one that uses \ (to do the inline \ (p={12\over q}\) Latex formula for the delimiterIn the following example, we have a large section of mathematical formulas, and we have another line to show:$$|\vec{a}|=\sqrt{a_x^2 + a_y^2 + a_z^2}.$$These two models are basically enough, and the specific Latex syntax must be self-GoogleUsing Latex to edit paper-level
