如何使用ConfigObj更新属性文件

Question

Is their any way for updating value of a key in properties file using ConfigObj in python.

Before updating properties file:

hostKey = "value"

After updating properties file:

hostKey = "updatedValue"

Answer 1

From ConfigObj Documentation

Creating a new config file is just as easy as reading one. You can specify a filename when you create the ConfigObj, or do it later [2].

If you don't set a filename, then the write method will return a list of lines instead of writing to file. See the write method for more details.

Here we show creating an empty ConfigObj, setting a filename and some values, and then writing to file :

from configobj import ConfigObj
config = ConfigObj("test.config")
config.filename ="test.config"
config['keyword1'] = "value6"
config['keyword2'] = "value2"
config.write()

I think similar way u can read and set to the same file name and then over-write the property you want.

This should help.

from configobj import ConfigObj
config = ConfigObj("FileName")

print(config['hostKey'])
config['hostKey'] = "updatedValue"        #Update Key
config.write()                            #Write Content
print(config['hostKey'])                  #Check Updated value.
