Modify INI file with Python

I have an INI file I need to modify using Python. I was looking into the ConfigParser module but am still having trouble. My code goes like this:

config= ConfigParser.RawConfigParser()
config.read('C:\itb\itb\Webcams\AMCap1\amcap.ini')
config.set('Video','Path','C:\itb\itb')

But when looking at the amcap.ini file after running this code, it remains unmodified. Can anyone tell me what I am doing wrong?

You could use python-benedict, it's a dict subclass that provides normalized I/O support for most common formats, including ini.

from benedict import benedict

# path can be a ini string, a filepath or a remote url
path = 'path/to/config.ini'

d = benedict.from_ini(path)

# do stuff with your dict
# ...

# write it back to disk
d.to_ini(filepath=path)

It's well tested and documented, check the README to see all the features:

Install using pip: pip install python-benedict

ConfigParser does not automatically write back to the file on disk. Use the .write() method for that; it takes an open file object as it's argument.

config= ConfigParser.RawConfigParser()
config.read(r'C:\itb\itb\Webcams\AMCap1\amcap.ini')
config.set('Video','Path',r'C:\itb\itb')
with open(r'C:\itb\itb\Webcams\AMCap1\amcap.ini', 'wb') as configfile:
    config.write(configfile)
