import os

def GetFileList(dir, fileList, nameList):
    #文件列表fileList
    #只取文件名的列表nameList
    newDir = dir
    if os.path.isfile(dir):
        fileList.append(dir.decode('gbk'))
        nameList.append(os.path.basename(dir.decode('gbk')))
    elif os.path.isdir(dir):
        for s in os.listdir(dir):
            if s == ".popoCloud":
                continue
            newDir=os.path.join(dir,s)
            GetFileList(newDir, fileList, nameList)

    return fileList, nameList

fileList = []
nameList = []
#你存放fas文件的目录,如：
#dir = 'd:/xxx/xxx/'
dir = (os.getcwd() + '\\fas\\').replace('\\','/')

fileList, nameList = GetFileList(dir, fileList, nameList)
print fileList, nameList

#根据你的要求替换文件内容
for i in range(fileList.__len__()):
    print fileList[i]
    fp = open(fileList[i],'r')
    #我不清楚你的每个fas有多大，如果比较大，就换一种读写方式
    str = fp.read()
    fp.close()
#     print str
    str = str.replace('>', '>' + nameList[i][:-4] +'_')
#     print str
    fp = open(fileList[i],'w')
    fp.write(str)
    fp.close()

print "OK"

效果如下：

[u'D:/workspace/PyDemo/fas/AAAA.fas', u'D:/workspace/PyDemo/fas/BBBB.fas', u'D:/workspace/PyDemo/fas/CCCC.fas'] [u'AAAA.fas', u'BBBB.fas', u'CCCC.fas']

D:/workspace/PyDemo/fas/AAAA.fas

D:/workspace/PyDemo/fas/BBBB.fas

D:/workspace/PyDemo/fas/CCCC.fas

看下面的代码，用函数 update_files('/path/to/fas/files') 可以将 /path/to/fas/files 目录下的所有 xxx.fas 文件做你需要的修改。（使用前注意备份，它会直接修改文件）

import os

def update_files(path):
    for f in os.listdir(path):
        if not os.path.isfile(f):
            continue
        name, sep, suffix = os.path.basename(f).rpartition('.')
        if sep != '.' or suffix != 'fas':
            continue
        with open(f, 'r') as fd:
            text = fd.read()
        with open(f, 'w') as fd:
            lines = ['>%s_%s' % (name, l[1:]) if l[0] == '>' else l
                     for l in text.splitlines(True)]
            fd.writelines(lines)

# update_files('/path/to')
# update_files('.')

如果只是这样的话，很简单的：

from glob import glob
for re_filename in glob("*.fas"):
    input_file = open(re_filename).read()
    new_file = open('new_'+re_filename,'w').write(input_file.replace('>','>'+re_filename[:-4]+'_'))
    new_file.close()

import os.path

def lineadjust(ln, fname):
    return ln.startswith(">") and (">%s_%s" % (fname, ln[1:])) or ln

def filecontextadjustbyname(fullname):
    fname, ename = os.path.splitext(os.path.basename(fullname))
    context = [lineadjust(ln, fname) for ln in open(fullname)]
    with open(fullname, 'wt') as handle:
        handle.writelines(context)

for filename in yourfilelist:
    context = filecontextadjustbyname(filename)

文件内容多不多？
