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 os
import sys
from collections import OrderedDict

def 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]
