Question

I had a text file with some information like this:

A , 12
B , 34
A , 54
F , 60

I want to read the file, and store the information in a python dictionary, like this: {‘A’:[’12’,’54’,…], B:[’34’,….]…} and so on. But I am stuck with how to search every A in lines. This is my tried:

    repo = {}
    infile = open('test10.log','r')
    lines = infile.readlines()[2:-1]
    for i in lines:
            module = ''.join(i.split(',')[:-1])
            time = ''.join(i.split(',')[1:]).replace('\n','')
            if not module in repo: 
                    repo[module] = time

Thanks for your help!.

Answer 1

There is not such a data structure like {A:{12,54,...}, B:{34,....}. However:

repo = {}
infile = open('test10.log','r')
lines = infile.readlines()[2:-1]
for i in lines:
    module, time = [a.strip() for a in i.split(',')]
    repo.setdefault(module, []).append(int(time))

will give you a dict of lists:

{'A': [12, 54], 'B': [34], 'F': [60]}

Is this what you want?
