Python：在fasta标头中添加增量ID

Question

我尝试使用标题中的增量ID从.csv文件创建多个fasta。但我的脚本效果不好。有什么建议吗？

M=open('/home/anna/Scrivania/db_mat/matk_2db_c.csv','r')
M_out=open('/home/anna/Scrivania/db_mat/db_matk_bronx.fas', 'w')

for i in range[1,92]:
    num = "m" + str(i)
for line in M:
    line1=line.split(',')
    ID = line1[0]
    SEQ = line1[1]
    seq =line1[2]
M_out.write('>'+ num +'_' +ID +'_'+ SEQ +'\n' + seq )

M.close()
M_out.close()

Answer 1

for i,line in enumerate(M,1):
    num = "m"+str(i)
    line1=line.split(',')
    ID = line1[0]
    SEQ = line1[1]
    seq =line1[2]
    M_out.write(...)

这只是通过线条枚举并给出一个1..N的索引，其中N是行数

在你遍历所有的nums之前，所以当你到for line in M时，所有行的num等于“m91”
