如何像tsv一样从python保存输出 [英] How to save output from python like tsv

问题描述

我正在使用biopython软件包，我想保存tsv文件之类的结果.此输出从打印到tsv.

I am using biopython package and I would like to save result like tsv file. This output from print to tsv.

for record in SeqIO.parse("/home/fil/Desktop/420_2_03_074.fastq", "fastq"):
    print ("%s %s %s" % (record.id,record.seq, record.format("qual")))

谢谢.

推荐答案

这很简单，除了打印它，您还需要将其写到文件中.

That is fairly simple , instead of printing it you need to write that to a file.

with open("records.tsv", "w") as record_file:
    for record in SeqIO.parse("/home/fil/Desktop/420_2_03_074.fastq", "fastq"):
        record_file.write("%s %s %s\n" % (record.id,record.seq, record.format("qual")))

如果要命名文件中的各个列，则可以使用:

And if you want to name the various columns in the file then you can use:

record_file.write("Record_Id    Record_Seq    Record_Qal\n")

因此完整的代码可能如下所示:

So the complete code may look like:

with open("records.tsv", "w") as record_file:
    record_file.write("Record_Id    Record_Seq    Record_Qal\n")
    for record in SeqIO.parse("/home/fil/Desktop/420_2_03_074.fastq", "fastq"):
        record_file.write(str(record.id)+"  "+str(record.seq)+"  "+ str(record.format("qual"))+"\n")
