Error in configparser

[fullstop]

I have a configuration file (abc.ini)as below

[DEFAULTS]
plus = plus.jpg

[PATHS]
folderPath = None

import configparser
config = configparser.ConfigParser()
config.read("abc.ini", encoding="utf-8")
print(config.sections())  # works ok
config["PATHS"].folder_path = path  # path is some path 

I don't understand whats happening in config["PATHS"].folder_path = path
when I do config["PATHS"]["folder_path"] I am getting an error.

Also, to access a value, we can use config["PATHS"]["folderPath"]
but can't we use config["PATHS"].folderPath

[Larz60+]

you should use the builtin: https://docs.python.org/3/library/configparser.html
The .ini file is used like a dictionary, thus the ["PATHS"]["folder_path"] access method

dear Larz60+

thanks for the reply
when i use config ["PATHS"]["folder_path"] i get error

[buran]

you have extra [ at the end of PATHS

thanks, but that was just a typo.

hi
my only problem is what is happening in config["PATHS"].folder_path = path

[buran]

obviously you don't want help.
Post the traceback.
Or try Larz solution, which WORKS
config["PATHS"].folder_path is invalid syntax as he explains

As mention can not use . access as the dictionary return has not folder_path mapped to it.
Guess get would work.
Quick test.

import configparser

config = configparser.ConfigParser()
config.read("abc.ini", encoding="utf-8")
config.sections()

>>> config["PATHS"]["folderPath"]
'None'

# Using get
>>> config["PATHS"].get('folderPath')
'None'

>>> path = 'eggs'
>>> config["PATHS"]["folderPath"] = path
>>> config["PATHS"].get('folderPath')
'eggs'

>>> # Using get can handle errors to
>>> config["PATHS"].get('foo', 'Not in config ini file')
'Not in config ini file'

I have a config file (abc.ini) as below. It just have one Section with an item name= None

[Section]
name = None

Now I am calling this in my main python code as below

import configparser
config = configparser.ConfigParser()
config.read("abc.ini",encoding="utf-8")
config["Section"].new_var = "surname"

Now my problem is with last line of code. This works ok. If I check the type config["Section"].new_var, it is of class str. Now if new_var is not a method or attribute of config["Section"], how it works OK.
Also, it it not adding any item to Section. I mean if I do
print(config["Section"]["new_var"]), I will give an error
