dear pythonistas in the code below
>>> import string, itertools >>> s = ['ab','ac','bc','ad','ae','de'] >>> count = 0 >>> for startlist in itertools.combinations(s, 3): >>> count = count + 1 >>> stl = list(startlist) >>> print count, stl >>> for pair in s: >>> x = stl.count(pair) >>> print x, pair the variable stl produces 20 lists. The variable x counts how many times the items of s occur in each of the 20 lists. How can I concatenate the 20 lists in oder to get one count for each of the items in s , for example 10 for 'ab'? My further task will be expand s to all 26 letters oft he alphabet (giving 325 items) and the to eliminate all list in which the items in s occur more than once. Thank you for help, Marcus. --- Diese E-Mail wurde von Avast Antivirus-Software auf Viren geprüft. https://www.avast.com/antivirus _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
