Question

I need to store configurations (key/value) for a Python application and I am searching for the best way to store these configurations in a file.

I run into Python\'s

Dictionaries are pretty popular as well. Basically a hash table.

{"one": 1, "two": 2} is an example, kind of looks like json.

Then you can call it up like mydict["one"], which would return 1.

Then you can use shelve to save the dictionary to a file:

mydict = shelve.open(filename)
# then you can call it from there, like
mydict["one"]

So, it's somewhat easier then an ini file. You can add stuff just like a list or change options pretty easily and then once you close it, it will write it back out.

Heres a simple example of what i mean:

import shelve

def main():
    mydict = shelve.open("testfile")
    mydict["newKey"] = value("some comment", 5)
    print(mydict["newKey"].value)
    print(mydict["newKey"].comment)
    mydict.close()


class value():
    def __init__(self, comment, value):
        self.comment = comment
        self.value = value



if __name__ == '__main__':
    main()
