在读取“ .ini”文件时获取“ KeyError”

Question

I have a python project in PyCharm, i have a following directory structure:

MyProject
 |_d1
   |_d2
     |_d3
      |_Main.py
      |_config.ini

config.ini

; config.ini
[DEFAULT]
SECRET_KEY = secret-key-of-myapp

main.py:

    config = configparser.ConfigParser()
    config.read('config.ini')
    print('==>', config.sections())
    secret_key = config['DEFAULT']['SECRET_KEY']
    print(secret_key)

I am getting this error

  raise KeyError(key)
KeyError: 'SECRET_KEY'

Answer 1

when I run the program , it gives me the following. I use python 3.7 for testing. reference: https://docs.python.org/3/library/configparser.html

import configparser

config = configparser.ConfigParser()
config.read('config.ini')
print('==>', config.__dict__)
secret_key = config['DEFAULT']['SECRET_KEY']
print(secret_key)
