This is probably a simple question that I am just missing but I have two lists containing strings and I want to “bounce” one, element by element, against the other returning the index of the matches. I expect there to be multiple matches and want all of the indices. I know that list.index() gets the first and you can easily get the last. For example:
list1 = ['AS144','401M','31TP01'] list2 = ['HDE342','114','M9553','AS144','AS144','401M']
Then I would iterate through list1 comparing to list2 and output:
[0,0,0,1,1,0] , [3,4]
or etc for the first iteration[0,0,0,0,0,1] , [6]
for second
and[0,0,0,0,0,0]
or[]
for thirdEDIT:
Sorry for any confusion. I would like to get the results in a way such that I can then use them like this- I have a third list lets call list3 and I would like to get the values from that list in the indices that are outputed. ielist3[previousindexoutput]=list of cooresponding values
Personally I’d start with:
matches = [item for item in list1 if item in list2]
