Splitting a string based on a list

I have a list like this: destinations = ['one', 'two', 'three']. I have an input string that I am splitting like this: one, two, three = re.split(r'\t', line). What I'd like to do is have the split operation fill a dictionary, with the destinations entries being the keys of the dictionary, and the fields from the line being the values. Is this possible with python?

Use the zip() function to pair up destinations and the output of re.split() into key-value pairs, then pass that to dict():

dictionary = dict(zip(destinations, re.split(r'\t', line)))

I suspect you are trying to read tab-separated CSV data; try not to reinvent the wheel and use the csv.DictReader() class instead. It'll even read the fieldnames from the first row of the file, if so required.
