python读取文本中的内容

1、获取路径符

pathseq = os.path.seq

2、文本中获取内容

import osimport sysfrom collections import OrderedDictdef get_content_frm_cfg( srcfile ):    src = open(srcfile, 'r+')    lines = src.readlines()    ret = OrderedDict()    for line in lines:        line = line.strip()        if len(line) == 0            continue        if line.strip().startswith('#'):            continue        pairs = line.partition('=')        key = pairs[0].strip()        val = pairs[1].strip()        ret[key] = val    src.close()    return ret

3、将内容写入文本

def write_content_to_cfg(dict, dstfile):    file = open(dstfile, 'w')    for key in dict.keys():        if re.search(':', key):            file.write(key + '\n')        else:            file.write(key + ' = ' + dict[key] + '\n')    file.close()

4、获取目录下某类型的文件

def get_raw_flie(srcdir):    bfile = 0    if os.path.isdir(srcdir):        filelist = os.listdir(srcdir)        files = [srcdir + '/' + f for f in filelist if re.search('.txt$', f) or re.search('log$', f)]    elif os.path.isfile(srcfile):        bfile = 1        files = [srcdir]    else:        files = []        print('Error')    return [files, bfile]
