Python receives arguments in the form of an array argv. You can use this to create the dictionary in the program itself.

import sys
my_dict = {}
for arg in sys.argv[1:]:
    key, val=arg.split(':')[0], arg.split(':')[1]
    my_dict[key]=val

print my_dict

For command line:

python program.py key1:val1 key2:val2 key3:val3

Output:

my_dict = {'key3': 'val3', 'key2': 'val2', 'key1': 'val1'}

Note: args will be in string, so you will have to convert them to store numeric values.

I hope it helps.
