So, I have this settings.ini :
[SETTINGS]
value = 1
And this python script
from ConfigParser import SafeConfigParser
parser = SafeConfigParser()
parser.read('settings.ini')
print parser.get('SETTINGS', 'value')
As you can see, I want to read and then replace the value "1" by another one. All I was able to do so far is to read it. I searched on the net how to replace it but I didn't find.
As from the examples of the documentation:
https://docs.python.org/2/library/configparser.html
parser.set('SETTINGS', 'value', '15')
# Writing our configuration file to 'example.ini'
with open('example.ini', 'wb') as configfile:
parser.write(configfile)
parser and the filename would match given question, i.e. 'settings.ini' to actually change the file contents.Python's official docs on configparser illustrate how to read, modify and write a config-file.
import configparser
config = configparser.ConfigParser()
config.read('settings.ini')
config.set('SETTINGS', 'value','15')
with open('settings.ini', 'w') as configfile:
config.write(configfile)
I had an issue with:with open
Other way:
import configparser
def set_value_in_property_file(file_path, section, key, value):
config = configparser.RawConfigParser()
config.read(file_path)
config.set(section,key,value)
cfgfile = open(file_path,'w')
config.write(cfgfile, space_around_delimiters=False) # use flag in case case you need to avoid white space.
cfgfile.close()
It can be used for modifying java properties file: file.properties
with open ... Your solution works. Only the comment has a small typo ("case case") and Java-related properties file note is a bit confusing here, because question is about INI file 😏️Below example will help change the value in the ini file:
PROJECT_HOME="/test/"
parser = ConfigParser()
parser.read("{}/conf/cdc_config.ini".format(PROJECT_HOME))
parser.set("default","project_home",str(PROJECT_HOME))
with open('{}/conf/cdc_config.ini'.format(PROJECT_HOME), 'w') as configfile:
parser.write(configfile)
[default]
project_home = /Mypath/
str(PROJECT_HOME) is not necessary, because PROJECT_HOME is defined as a string. So, I think, this should work the same: parser.set("default","project_home",PROJECT_HOME)
