本文關鍵給大家介紹了Python完成GB文件格式編碼序列編碼序列Fasta文件類型實例詳細說明，感興趣的小伙伴可以參考借鑒一下，希望可以有一定的幫助，祝愿大家盡可能發展，盡早工作上得到晉升

　　GB文件類型和FASTA文檔詳細介紹

　　在生物學中會有將GB文件格式編碼序列編碼序列成Fasta文件類型的需要，接下來我們運用python腳本制作來解決這些問題。

　　gb格式文檔是GenBank的文檔，用于儲存編碼序列的詳細資料。包括一個gene的名字，序號，發現人，論文參考文獻，外顯子部位，編碼區編碼序列，蛋白序列等等信息。

　　比如：

　　fasta格式是一種基于文本用于表示核酸序列或多肽序列的格式。其中核酸或氨基酸均以單個字母來表示，且允許在序列前添加序列名及注釋。該格式已成為生物信息學領域的一項標準。

　　處理步驟

　　將文件夾下gb文件批量讀取

　　將各個gb文件中的登錄號和具體序列抽提出來，并寫入fasta文件

　　將fasta文件進一步處理去掉換行符，使一個完整的序列中沒有換行符

　　將所有處理好的fasta文件存入一個新建的子文件夾中

　　Python腳本代碼如下：
