Python adding dictionary values from separate script runs -

i have dictionary generated within script:

dict1 = {'a': 1, 'b': 2, 'c':3}

the script generate dictionary run many times on different files generate more dictionaries, each within own script:

dict2 = {'a': 5, 'b': 3, 'c':2} dict3 = {'a': 2, 'b': 1, 'c':0}

my plan add these file individually, add values same key (e.g. 1 entry 'a': 8) once file has been appended dictionaries.

is there way add values of dictionaries they're added file? or other way results in values being added each script completes?

edit: i'm new coding, please explain , if can. :)

i wanted add new generated dictionary values pre-existing file.

for example, dict 1 in file. did

with open(file.txt, "w") f:         in dict.keys():             f.write(i + " " + str(dict[i]) + "\n")

to add dict 2, dict 3, etc file: took file.txt had dict1 , re-wrote dictionary

for line in f:             values = line.split(sep)             dict[values[0]] = int(values[1])

then added 2 dictionaries within program , re-wrote new dictionary out file.

probably not elegant answer, works!
