If we are talking about less code than necessary then probably we could use something from python's ecosystem... >>> import pandas as pd # really useful package >>> import io # I simlulate file in csv with header (like Deborah has) >>> data = """\ what,location foo,here foo,there bar,eberywhere""" >>> df = pd.read_csv(io.StringIO(data)) # reading csv into DataFrame is very >>> simple >>> print(df[df.what == 'foo']) # data where what == foo what location 0 foo here 1 foo there >>> list(df[df.what=='foo'].location.values) # list of values ['here', 'there'] >>> list(df.itertuples()) # if we want to use namedtuples [Pandas(Index=0, what='foo', location='here'), Pandas(Index=1, what='foo', location='there'), Pandas(Index=2, what='bar', location='eberywhere')] etc. -- https://mail.python.org/mailman/listinfo/python-list
