将python代码和注释分离的方法

时间:2021-10-05 16:57:34

python注释方式和C语言、C++、java有所不同

python语言中,使用‘#' 来进行注释,其次还有使用 三个引号来进行注释

本文的程序将把 python 中 使用‘#' 号 好 三个引号的注释分离出来, 当然也能再次合并回去

有需求的小伙伴可以来围观了

本程序已知问题, 不能处理 空格之后在以‘#' 开头的注释,所有的注释行,必须是顶格写的

以后有时间的话,再重新写一版完整的吧

以上这篇将python代码和注释分离的方法就是小编分享给大家的全部内容了,希望能给大家一个参考,也希望大家多多支持服务器之家。
