Practical Python method used in the project

1. Get the current working directory

import os        print os.getcwd()<pre name="code" class="python">    print os.path.abspath('.')

2. format the time string

import datetime    time_str=datetime.now().strftime('%Y%m%d-%H%M%S')

3. parse the configuration file

    config_path=r'D:\demo'    config_path=config_path.strip()    ini_file_name='Config.ini'    try:        config=ConfigParser.ConfigParser()        config.readfp(open(config_path+'\\'+ini_file_name,'rb'))                log_path=config.get('global', 'log_path')        log_name=config.get('global', 'log_name')        report_json_link=config.get('global', 'report_json_link')        proxy_address=config.get('global', 'proxy_address')        log=screenshot_log(log_path,log_name)    except Exception,e:        print 'get config info failed!!!',e        exit

4. json parsing method:

Json_str = json. dumps (a_object) # convert a Python object to a json string json_obj = json. loads (json_str) # convert a json string to a Python object

5. Determine whether a file or directory exists:

os.path.exists(your_path)
