Hello, I am a beginner in python. following program prints the second element in list of lists 4 for the first elements in list 4 that are common with the elements in list 5
list4 = [['1', 'a'],['4', 'd'],['8', 'g']] list5 = ['1', '2', '3'] for j in list4: for k in list5: if j[0] == k: print j[1] Result: a I would like to do the same thing starting with following lists, where the numbers in list 5 are without ''. Is there a way to convert integers in a list to integers in '' ? This is based on a situation where I want to find common numbers between a list and a list of lists where the numbers in the list are without '' and the numbers in the list of lists are with '' list4 = [['1', 'a'],['4', 'd'],['8', 'g']] list5 = [1, 2, 3] This might be a stupid question, but anyway, thanks for your answer It is not my first post on this site. In some way it is not possible to react on the messages that I receive to thank the persons that react. Anyway, thanks a lot -- http://mail.python.org/mailman/listinfo/python-list
