python配置文件ini读取

cfg.ini 如下所示

[email_qq]

sender = [email protected]
psw = 123456
port = 789
smtp_server = trf.qq.com

[email_163]

sender = [email protected]
psw = 123456
port = 789
smtp_server = yre.qq.com

读取cfg.ini的脚本

import configparser
import os

# 获取的__file__所在脚本的路径，也就是fileName.py的路径
curpath = os.path.dirname(os.path.realpath(__file__))
print(curpath)
cfgpath = os.path.join(curpath, "cfg.ini")
print(cfgpath)   # cfg.ini的路径

# 创建管理对象
conf = configparser.ConfigParser()

# 读ini文件
conf.read(cfgpath, encoding="utf-8")  # python3

# conf.read(cfgpath) # python2

# 获取所有的section
sections = conf.sections()
print(sections)  # 返回list

items = conf.items('email_163')
print(items)   # list里面对象是元组

宏定义：用于ini配置文件中拼接脚本

CMD_GET_META = "{} -v quiet -print_format json -show_format -show_streams {}"
file_cmd = CMD_GET_META.format('ffmpeg', '001.mp3')

print(file_cmd)

### 结果如下：
ffmpeg -v quiet -print_format json -show_format -show_streams 001.mp3
