Key:Value Pairs from txt file into a dictionary

I have a txt file with key value pairs. It can format (get, retrieve) the pairs from the file in multiple ways, for example:

as line separated strings with colons:

stringa1:stringa2
stringb1:stringb2

or as line separated strings with commas:

stringa1,stringa2
stringb1,stringb2

or as individuals lists of strings:

[stringa1,stringa2]
['stringa1','stringa2']

AND, I can assign each string to a variable with:

    for string in list
        splitstring=list.split(',')    
        for item in splitstring:
            print (item)
    >>>stringa1
    >>>stringa2

But I can't figure out how to add those key:value pairs to a dictionary

d[splitstring[0]] = splitstring[1]

should work, where d is a dict. That's the easiest way of adding a key, value pair to a dictionary.

Another way is:

d.update({splitstring[0]: splitstring[1]})

Taking in mind that we are talking about pairs, then this should work:

mydict = {}
for i in range(0,len(splitstring),2):
    mydict[splitstring[i]] = splitstring[i+1]
