將python代碼和注釋分離的方法

python的注釋方式和C語言、C++、java有所不同

python語言中，使用‘#' 來進(jìn)行注釋，其次還有使用 三個(gè)引號來進(jìn)行注釋

本文的程序?qū)?python 中 使用‘#' 號 好 三個(gè)引號的注釋分離出來， 當(dāng)然也能再次合并回去
有需求的小伙伴可以來圍觀了

本程序已知問題， 不能處理 空格之后在以‘#' 開頭的注釋，所有的注釋行，必須是頂格寫的
以后有時(shí)間的話，再重新寫一版完整的吧
以上這篇將python代碼和注釋分離的方法就是小編分享給大家的全部內(nèi)容了，希望能給大家一個(gè)參考
